Introduction
Non-destructive editing is one of the capabilities that distinguishes the HDR24/96
from your old tape recorder. It’s easy, it’s fun, and you won’t cut your fingers
learning how to do it. This guide will introduce you to the editing tools and
concepts.
All the editing operations are performed on screen through the Graphical User
Interface (GUI), so all the discussion in this section applies to GUI operations and
displays only. See page 13 of the Quick Start Guide for details on installing a
monitor, mouse and keyboard.
Once you are ready, sit down in front of your screen, take a deep cleansing breath,
reach for the mouse and let’s get started.
Regions
Regions are graphic representations of audio files — or portions of audio files —
stored on the hard drive. The HDR24/96 editor displays regions as boxes within a
track, each containing a waveform display of audio. It’s important to understand
the difference between regions — which just represent audio — and the actual
audio files: A region is information which tells the player at what time, relative to
the start of the audio file, to start playing a portion of the audio file, and when to
stop playing.
After a recording pass, a new region appears along a track, representing the new
audio file in its entirety. The region’s start and stop times are the same as the
beginning and end of the audio file. From this point, the region can be chopped up,
moved, copied & pasted, transferred to other tracks and more; completely
changing the song as it is heard, but without changing the original corresponding
audio file. Each piece becomes a new region, with new information as to where
along the audio file to start playing and where to stop.
If a region is deleted, it won’t play back (because there’s nothing telling the
HDR24/96 when to start playing the file) but its corresponding audio data is still
on disk. Even if all its regions are deleted, the audio file remains. That audio file
can be called back as a new region or erased from the disk.
If you’ve laid some tracks that you really don’t want disturbed, right-click on their
regions and select Lock from the pulldown menu.
An editing note regarding regions within Virtual Takes: Each track can contain up
to seven inactive virtual takes. These are safe from global editing operations only
when the tracks are collapsed so that only the active take is visible. If you are
performing global selections and chopping and plopping regions here’n’there,
make sure that only the virtual take that you want chopped is visible. Select it as
the active take, then collapse the track to keep the others safe from this Borg type
activity.

Track and Region Editing Tools
Your tool kit includes the I-Beam, Hand, Volume Envelope, and Magnifier tools.
The Scrub wheel isn’t really an editing tool, but it’s grouped on screen with them
because it interacts with the Hand and I-Beam tools, and it’s handy for locating
edit points.
An editing tool is selected by clicking on its button. Alternately, right-clicking in
the track area of the screen brings up a pop-up menu with a Tools option. Select
Tools, then select the tool you want. By using the pop-up menu to change tools,
you’ll keep your eyes and mouse hand right where you’re working.
There are keyboard shortcuts for the editing tools, which will help you to keep
your eye on the ball, and your nose to the grindstone:
T– Toggles between the I-Beam and Hand tools.
F1 – Selects the I-Beam tool
F2 – Selects the Hand tool
F3 – Selects the Volume Envelope tool
F4 – Selects the Magnifying tool

Editing Guide
Selection
Area Selection (I-Beam Tool)
The I-Beam tool is used to mark the start and end times of an area for editing
operations. It operates on a single track, a group of selected tracks, or all the
tracks.
Clicking and dragging the I-Beam across a track selects an area. The same
selection can be made on all tracks by clicking and dragging the I-Beam
across the time bar.
Once an area has been selected, the area boundaries and its position can be
adjusted in several ways:
• Placing the I-Beam cursor on either edge of a selection boundary turns
the cursor into a double-headed arrow. When this arrow appears, click
and drag the edge of the selection to move it. The selection boundaries
can also be dragged from the time bar at the top of the track area. The
selection is marked on the time bar by a gray band with its upper
corners darkened. Those dark corners are “handles” by which you can
drag the selection ends.
•CTRL-click on the Selection Range Start or End time field to capture
the current transport time into that field. This can be done either with
the transport stopped or while playing, to select an area on the fly.
• The entire selection (at its present length) can be repositioned by
dragging the gray area on the time bar.
Multiple Area Selection
To make the same selection on multiple tracks, after an area is selected on
one track, CTRL-click anywhere in another track’s area to duplicate the
selection on that track. Shift-clicking on another track will duplicate the
selection on all the tracks between the first one selected and the one on
which the mouse pointer is clicked.
Selection Range Display
The Selection Range Start and End time
fields in the Tools panel show start and
end times of the area currently selected
via the I-beam tool. This time display is
interactive with the selected area. The
area boundaries can be updated by
editing the numbers in the time fields.
Conversely, as the selection boundaries
are changed by dragging with the mouse,
the time fields are updated.

6
HDR 24/96
HDR 24/96
The time fields in the Selection Range Display can be edited as follows:
Click on the desired field in the Selection Range display to highlight the pair
of digits you wish to modify. Change the numbers by dragging the mouse up
or down over the highlighted digits or with direct numeric entry from the
keyboard. Navigate between hours, minutes, and seconds fields with the Tab
or Shift-Tab key or mouse. Complete the data entry with the Enter key
or by clicking in the Tools panel background area.
NOTE: If you manually enter a Start time which is later than the current End time,
the later time becomes the selection End time, and what was the former End time
becomes the new Start time.
Region Selection (Hand Tool)
The Hand tool is used for selecting (grabbing), moving, and resizing regions,
plus changing fade-in and fade-out curves. The Hand tool works on single or
multiple regions, so it’s possible to move or resize a group of selected regions
at one time. This is particularly handy for stereo tracks, or all of the drum
kit’s tracks.
A region is selected for editing by clicking anywhere in the region with the
Hand tool. The Hand tool’s function changes, depending on where it’s placed
in the active region area, with its cursor shape changing to indicate its
current function. Placing the Hand Tool cursor on either end boundary and
above a region’s centerline activates the fade adjustment tool. Below the
region’s centerline the cursor becomes a resizing tool. Within the region
boundaries, the Hand Tool’s hand cursor is used for dragging the region.
A region or regions (selected as group) may be dragged around with the Hand
tool and dropped on top of blank track area, on top of other regions or a little
bit of both. The Splice and Crossfade functions affect the way a region will
intersect or overlay another region.

Editing Guide
Editing Guide
Multiple Region Selection
Multiple regions can be selected and operated upon as a group (moving,
deleting, resizing, or changing crossfades) by CTRL-clicking on each region
of the desired group with the hand tool.
Double-clicking on a track number selects all the regions in the active take of
that track. If the track is expanded to show virtual takes, double-clicking on
any take number selects all the regions in that take, but does not change the
active take.
CTRL+A selects all regions in the project.
Magnifier
The Magnifier tool expands and contracts the region and track displays, allowing
you to take a closer look at the waveform on a track and zero in on your selection.
Single clicks with the Magnifier tool selected expand the track display
horizontally. Dragging the Magnifier across tracks and regions draws a box and
zooms the selected area both vertically and horizontally, like a magnifying glass.
CTRL-clicking with the magnifier tool active zooms out.
The “Dive” Key (Z)
The ‘Z’ key operates as a momentary zoom-in key for a high resolution view
around the current cursor position. Releasing the Zkey returns to the
previous screen view.
Node Tool
The Node tool allows adjustment of the volume level within a region (which could
be the entire track). For details on using it, please see page 16.
Cursor Location Display
This time display tracks the current time location of the cursor pointer, regardless
of the selected tool. It is a display function only.

HDR 24/96
Nudge Tools
This tweak tool set allows you to nudge selected regions, areas, or area selection
boundaries. Actions include moving regions, resizing regions, moving or resizing
region attributes (such as start, end or length) in specified time increments.
Multiple regions and region attributes may be selected and modified in the same
manner as single regions. Nudge tools are located on the Tools panel, just to the
right of the Selection Range time displays.
Nudge Resolution
The pulldown menu above the nudge tools selects the increment of one
“nudge” (a small amount of movement) in units of samples, SMPTE frames,
or fractions of a second.
Nudge arrows
The arrows surrounding the three Nudge Selection boxes nudge to the right
or left by the increment selected. What gets moved is determined by which
Nudge Selection box is selected.
Selection Start (left), Selection End (right), Selection (center) boxes
These three boxes select whether the left boundary, right boundary, or the
entire selection or region will be nudged. These are “radio buttons” - only one
may be active at a time. When the Hand tool is selected, the boxes contain a
waveform icon, indicating that a region will be nudged. When the I-Beam tool
is selected, the boxes show a divided block, indicating that a selection will be
nudged.
Selecting the left box causes the left boundary of the selection or region to be
nudged when the left or right arrow is clicked. Similarly, selecting the right
box and clicking on an arrow will nudge the right boundary in the direction of
the arrow. Selecting the center box causes the complete region or selection
area to be nudged when a direction arrow is clicked, without changing its
length.

Scrub Wheel
The Scrub Wheel tool is the round wheel at the right-hand end of the group of
editing tool buttons. Its function is similar to “rocking the reels” of a reel-to-reel
tape deck. Scrubbing allows playback at slow speed, even in reverse, to locate an
edit or punch-in point the old fashioned way - by ear. The Scrub function is
engaged by clicking on the Scrub Wheel button to highlight it. The Skey
momentarily activates the Scrub tool, turning it off when you release the key.
When Scrub is engaged, clicking and dragging the mouse pointer horizontally
along the Marker Bar at the top of the track screen starts the transport playing on
all 24 tracks. Dragging it to the right plays forward, dragging it to the left plays
backward. The mouse acts as a throttle - the further you drag it, the faster the
transport plays, up to full speed. By using a side-to-side motion with the mouse
and listening to the playback, you can zero in on a point in the track that you’re
trying to locate.
If you want to scrub just a single track, with the I-Beam and Scrub tools both
active, place the cursor on the track you want to hear, then click, and scrub.
Caution: Selecting the Scrub tool does not automatically deactivate the Hand
tool. If you scrub on a region with the hand tool active, you won’t scrub, you’ll
move the region.
Edit Clipboard
Cut, copy and paste editing operations are performed through the Clipboard. The
HDR24/96 clipboard follows the conventions common to word processors and
other computer-based editing tools. The editing clipboard buffer holds the result of
a single cut or copy operation (which could be performed on multiple items if
selected). The cut or copied section remains on the clipboard until replaced by the
next cut/copy operation.
For example, if two region Copy operations are performed successively, only the
second selection copied remains on the clipboard, with the first copied selection
going into the bit bucket to make room for the second. As long as a copy remains
on the clipboard, it may be pasted any number of times and to any location.
Each cut and paste operation is recorded on the History list. This possibly very
long edit list is retained only as long as the Project file is open.
History List Entries
With the history list, editing isn’t like heart surgery –
the History list offers a safety net to undo any series
of editing operations. The History List is discussed in
detail in the List Panel section of the Technical
Reference Guide. It’s important to mention here
because the history that’s listed, in addition to
recording passes, is that of all of your editing
operations. It’s the key to nondestructive editing. By
deleting entries from the History list, you can undo
any editing operation.
The following activities are recorded in the History
List and may be undone as long as the list remains
active for the project: Record pass, split, crop, cut,
copy, paste, move region(s), resize a fade-in, resize a

10
HDR 24/96
HDR 24/96
fadeout, and resize a region. The only thing that isn’t recorded on the History list
is region Envelope modifications – node additions, movements or erasure.
Note: Backing up to or prior to a Record pass in the edit list is destructive. If you
undo a Record pass, you can’t recover that recorded audio, nor can you redo any
editing operations that followed the Record pass on the list.
Cut
Cut removes the current selection (on one or multiple tracks) from the track area
and places it on the clipboard. You can Cut either an area selection made with the
I-Beam tool (on one or multiple tracks) or a region selected with the Hand tool.
Cut works contiguously across empty track space in the selected area – i.e.
unrecorded sections within the selected area are placed on the clipboard along
with recorded audio in the selected area. If pasted elsewhere, the pasted section
will include the blank spaces.
The Cut command is accessible from the pulldown Edit menu at the top of the GUI
screen, or by clicking on the CUT button on the Tools panel. The keyboard
shortcut is CTRL+X.
Delete
The keyboard Delete key is slightly different than Cut. It indeed cuts, but it does
not place the cut segment on to the clipboard. After a Delete operation, the
clipboard retains its previous contents. Delete is entered on the History List, so it
can be undone.
Copy
The Copy command copies the selection(s) or selected region(s) from the track
area to the clipboard. A region or selection is unaffected by a Copy operation. It
remains where it was. Like Cut, Copy works contiguously across empty track
space in the selected area – i.e. empty track space which is included in the area
marked for copying is placed on the clipboard along with areas of recorded audio.
If pasted elsewhere, the pasted section will include the blank space.
The Copy command is accessible from the pulldown Edit menu at the top of the
GUI screen, or by clicking on the COPY button on the Tools panel. The keyboard
shortcut is CTRL+C.
Paste
Paste places the current contents of the clipboard into the selected track,
beginning at the Current Time line. When multiple regions are pasted in, the
relative time between the regions remains intact, with the start of the leftmost
(earliest) region to be pasted falling on the Current Time line.
The Paste command is accessible from the pulldown Edit menu at the top of the
GUI screen, or by clicking on the PASTE button on the Tools panel. The keyboard
shortcutisCTRL+V.

Editing Guide
Editing Guide
Paste Repeat
The Paste Repeat operation is used in a similar fashion to Region looping (see
page 20). It works the same as Paste except that the Paste operation is repeated
automatically for a specified number of times, and at a specified interval. The
Paste Repeat function can include multiple regions and silent space in between
regions, whereas the Loop Region operates on one region only. The default Paste
Repeat interval is the length of the selection so that the pasted regions are placed
end-to-end, but this can be edited from the Paste Repeat dialog box.
Splice Mode
The SPLICE button, located near the center of the Tools panel, affects how cut
and paste operations are performed. It’s analogous to tape splicing, hence its
name. If Splice is turned off, cutting a selection out of a region leaves a hole,
perhaps to be filled by an equivalent part from an alternate take. If Splice is
turned on, the two sections on either side of the cut are automatically joined
together by the Cut operation. The earlier section of the region stays put and the
later section (everything to the right, even if there are several regions) slides
forward in time to join it.
When pasting, if Splice is off, the pasted-in section is simply plopped down on top
of the existing region, replacing what was there. If Splice is on, the old track is
divided at the point where the section is pasted, and slides over to make room for
the pasted-in piece.
With Splice off, when multiple regions with a gap (no audio) between them are
pasted to another track, only sections where there is recorded audio will overwrite
what’s existing on the track. In other words, audio existing on the pasted-to track
will be audible in the gaps between the newly pasted regions. If Splice is enabled,
gaps in the pasted-in regions will remain. This is consistent, since the original
track moves out of the way to make room for the spliced-in section, leaving a
space with no audio to poke through the holes.
NOTE: SPLICE only works with clipboard (cut and paste) operations. It doesn’t ap-
ply when dragging a region to a new location with the hand tool.
Snap and Snap-to Functions
When Snap is enabled, dragged objects such as regions or selection lines no
longer move smoothly, with seemingly infinite resolution. Instead they snap to
fixed time increments with magnetic allegiance - i.e. they move smoothly, but
when a virtual (and invisible) grid line is crossed, they stick briefly so you’ll know
you’re in line time-wise with the snap grid. Regions, region boundaries, and
selection boundaries are all affected by the Snap function.
Whenever Snap is enabled, the Current Time bar is also the “snap-to” point, even
if it’s between snap grid lines.
Snap Enable
The Snap controls are found under the Options pulldown menu or from a
menu which pops up when right-clicking on the time bar. Snapping is turned
on or off by clicking on the SNAP button in the Drag/Edit section of the GUI
Tools panel or by selecting Enable Snapping in the Options or pop-up menu.
From either menu, you can select Snap to Grid, Snap to Cues, or both. You
can also select the grid resolution from another pulldown under this menu.

12
HDR 24/96
HDR 24/96
NOTE: Enable Snapping is the on/off switch. If you want to use snapping, you
must select this. It is not sufficient to select Snap to Cues or Snap to Grid by it-
self. If Snapping is enabled with Cues and Grid turned off, a dragged region will
snap to the current time bar or the edge of an adjacent region.
Snap to Grid
The resolution of the grid is set from the Snap Grid submenu. There are both
time (minutes, seconds, frames) as well as musical (bar, quarter note, eight
note, etc.) increments which can be selected as grid increments. In addition,
you can snap to Ruler Marks, which are the divisions along the time bar at
whatever the current time scale is. This option is helpful for working within
the context of the current view - for fine snap increments while zoomed in and
for larger increments when zoomed out.
Time Snap resolutions are as follows:
Minutes
Seconds
Frame
For musical applications (when working in bars beats and ticks) a tempo map
can be imported from a Standard MIDI file, so that snapping to musical
intervals follows tempo changes in the song. If the project is at a fixed tempo
throughout (disco lives!), the tempo from which BBT is calculated can be set
from the MIDI Setup menu. The default tempo is 120 BPM, with a fixed
resolution of 480 ticks per quarter note. The BBT snap resolutions are as
follows:
Bar
Half note - snap to this resolution
Half Note triplet
Quarter note
Quarter note triplet
Eighth note
Eighth note triplet
Sixteenth note
Sixteenth note triplet
Snap to Cues
When Snap to Cues is enabled, the snap function will allow dragged objects
and selections to ‘cling’ to any nearby Cue time.

Region Manipulation Tools and Functions
The I-Beam and Hand tools are used to redefine and adjust the Start or End of
regions. As a reminder, the start and end points of the region that you see on the
screen may not necessarily be those of the original audio file.
Split
The audio editing process involves cutting large chunks of audio into small pieces
and rearranging those pieces in creative ways. The Split function is used to chop
a region (typically starting with a recording pass) into pieces for editing.
The SPLIT button is located along the bottom of the GUI tools panel. Split can
also be accessed from the Edit pulldown menu, however the choice will be grayed
out unless there’s a marked area or the Current Time bar is bisecting a region – in
other words, the option is only available when there’s something to split.
To divide a region, place the Current Time bar at the desired split point and click
on the SPLIT button. You now have two regions. If you select an area within a
region using the I-Beam tool, SPLIT creates three regions, one consisting of the
selected area, one before the selected area, and one after. Each region carries the
name of the track and take. Renaming the pieces using the Region Editor will help
you to keep track of those little bits of virtual tape for later use.
Splitting follows all the rules of selection. If multiple selections are made, they’ll
all be split with a single command.
Crop
Crop operates in conjunction with a selected area within a region, deleting
everything in the region that is outside of the selection. It follows the selection
rules so a single Crop command will crop multiple tracks with defined selections.
Since there must be something useful left after cropping, Crop only functions on a
selection width of 1 frame or greater.
CAUTION: Be careful when cropping. Crop operates on both sides of the selected
area. If your intent is to chop off the beginning of a region but not the end, be
sure your selection area extends safely outside the region boundary on the end
you want to keep.
The CROP button is located along the bottom of the GUI tools panel. It can also
be accessed from the Edit pulldown menu when an area is selected.
Moving Regions - Click’n’Drag
With the Hand tool active, you can click on a region and drag it anywhere in the
track area. This is, in essence, a combination of the copy and paste commands in a
single operation. There are a couple of variations:
CTRL-click when dragging combines Copy and Paste operations, leaving the
region in its original place and putting a copy elsewhere in the track area.
Shift-click when dragging allows you to move a region, but constrains it in
time. It can move vertically (to another track or take) but can’t move horizontally.
This is particularly useful when building a composite track from multiple takes. It
keeps things locked in time (of course you can do fine adjustments later).

14
HDR 24/96
HDR 24/96
CTRL-shift-click when dragging combines the two above operations. A time-
constrained copy of the selected region is place on another track without
disturbing the original regions.
NOTE: Copying in this manner does not place the copied segment on the Clip-
board. Like the Delete key, the Clipboard retains its original contents.
Insert Time
Insert Time inserts a specific amount of blank space into the selected Track(s). It
is a combination of Split and Paste with Splice enabled, except that blank space is
pasted instead of the contents of the copy buffer. The default position for the
insertion is the location of the Current Time bar. If the Current Time bar intersects
a Region on a selected Track, then the Region is Split and blank space is inserted
at that point.
When an I-beam area selection is made, the amount of time inserted defaults to
the length of the selected area, starting at the beginning of the selection area.
When the insert point is selected with the Hand tool, the length of the insert time
defaults to 0 and must be manually entered in the Insert Time dialog box.
To Insert blank Time into one or more Tracks:
Select the insert point and track(s) you want to Insert Time into, then select
Insert Time from the Edit menu, or use keyboard shortcut CTRL+I. In the
Insert Time dialog box, modify the Amount of time to be inserted and the
Insert Position as necessary, and click OK.
Fades
A 10 millisecond fade is automatically generated at the beginning (fade-in) and
end (fade-out) of every region. These fades occur at the start and stop of any
recording, and also at the ends of any Cut or Split within a region. The duration of
the fade and its shape can be adjusted from the Region Editor dialog box (see page
17) or by dragging the inside edge of the fade area with the hand tool.
Right clicking in the fade area will pop up a menu to change the shape of the Fade-
in or Fade-out curve.

Editing Guide
Auto X-Fade (Crossfade)
When assembling chunks of audio, crossfading between two adjacent sections is
often employed to make the transition between them sound seamless. In razor
blade editing, we crossfade by making a diagonal cut across the tape, creating a
small portion of time where both sections are playing together. When crossfading
is active on the HDR24/96, a crossfade is automatically generated over the entire
overlapping area when one region is placed on top of another. The outgoing audio
fades down, while the incoming audio fades up.
Crossfade time on the HDR24/96 is adjustable from zero to nearly the entire
region length, with three different volume curve shapes. The crossfade occurs in
the area where the regions overlap, but, since regions and crossfade times can be
resized at any time, it’s easy to move the point at which the crossfade begins and
adjust the crossfade length for a smooth-sounding transition. Zooming in to the
crossfade area will help you to visualize what you’re hearing, but you should
always evaluate your edits by ear.
When performing musical
edits, it is important not
only to place the edit so
that musical timing is
correct, but to choose a
splice point so that the
splice is inaudible.
Experiment with
crossfade time and splice
position to obtain the
smoothest edits.
The AUTO X-FADE
button is located in the
Drag/Edit section of the
GUI tools panel. It toggles
between a crossfade
extending over the entire
overlapping area (AUTO
X-FADE On) and a fixed, 10 millisecond fade at the boundary of the two
overlapping regions (AUTO X-FADE Off). On or off, however, there will always be
a finite crossfade time when regions overlap unless you manually shrink it to zero.
The crossfade curves (rate of change of volume) come in three flavors - slow, fast
and linear. These can be selected from the Region Editor or from a pop-up menu
when right-clicking in the crossfade area. The crossfade is represented in the on-
screen waveform view by a red line which is easily visible when zooming in on a
splice.
See the note on the next page....

16
HDR 24/96
HDR 24/96
NOTE: When splicing together two continuous waveforms (shortening a
Didgeridoo solo, for example) that are close to full scale amplitude, it’s possible
that they’ll attempt to sum to greater than full scale in the crossfade region. This
will both sound ugly and look ugly if you zoom in on it. Attack this problem by
changing the shape of the crossfade curve so that both sections aren’t near full
gain simultaneously.
Toggling the AUTO X-FADE function on or off will not affect any currently existing
crossfades. Crossfades become part of the region, so if a region spliced with a
crossfade is moved elsewhere, the crossfade will be carried along with it.
Volume Envelope (Node) Tool
The Node tool allows adjustment of the volume level within a region (which could
be the entire track). The pencil cursor is used to add nodes, or inflection points at
which the volume can be changed. Clicking on the volume envelope line with the
Node tool drops a node on the line. Nodes can be dragged along the volume
envelope line horizontally or vertically. By inserting nodes at the appropriate
places, you can create a mute, duck a note or word, or do a custom fade-in or fade-
out.
Holding the CTRL key with the Node tool active, changes the pencil to an eraser
for deleting nodes. When a node is deleted, the line straightens out to connect the
remaining nodes. When all nodes are deleted, you’re back to a straight line.
The first node you place in a region will be placed at unity gain (0 dB). You can
increase the audio level within the region by up to 6 dB, or lower it all the way
down to zero. While not a replacement for mix automation, it’s handy for muting
portions of a track, or adjusting the level of a punch-in so that it matches the rest
of the track.
There are nodes at the beginning and end of the region which cannot be deleted
(without them, there wouldn’t be anything to define the line), though they can be
dragged vertically to adjust the overall volume of the region.
Pressing the Shift key when the Node tool is active turns the pencil cursor into
a double-headed vertical arrow. This tool allows you to drag the envelope line
vertically and parallel to itself. In reality, it’s dragging the pair of nodes that define
the line segment. If the envelope line is horizontal, Shift-clicking and dragging
the line adjusts the overall playback level of the track.
Note: Volume Envelope functions are interactive with the Envelope Active switch
in the Region Editor, and the View Envelopes setting in the Options menu. See
Page 19 for additional details.

Region Editor
The Region Editor displays and defines (for the selected region) many of a region’s
attributes:
• Region name
• Start time
• End time
• Region length
• Whether the Volume Envelope is Active
• Whether Region Loop is enabled
• The region’s Fade-in and fadeout length
• The region’s Fade-in and fadeout curve shape
• Region Lock function
The Hand tool must be active in order to select regions to be edited with the
Region Editor. The Region Editor dialog box may be opened by:
• Double clicking (either right or left) on the region.
• Right-clicking on the region with the Hand tool and selecting Region Edit
from the pull-down menu which appears.
• Selecting the region with the Hand tool and using the keyboard shortcut
CTRL-E.
• Selecting Region Edit from the GUI top level menu Edit menu.
Once the Region Editor is open, you can select any region and the Region Editor
dialog box will update with data from the selected region.
Here’s what you’ll find in the Region Editor dialog box:
The following pages describe some of the details.

Region Name
The name of a region is inherited from the track name at the time of the recording.
Regions created as a result of Capture, Import or Rendering operations also carry
the track name. If a track is renamed, subsequently created regions from that
track will inherit the new track name, but previously created regions are not
automatically renamed when the track name changes.
The name that appears in the upper left corner of the region block is updated when
the Name field in the Region Editor is updated, either by exiting the Name field or
clicking on another region or portion of the track area.
To edit the region name in the dialog box, double click on the Name field to
highlight it, then enter the new name.
NOTE: It is possible, and even pretty darn easy, to have more than one region with
the same name within a project, originating from the same or different audio
files. It is also possible to have a region with no name - i.e. left blank or erased on
purpose. There’s nothing functionally wrong with that as long as you have some
way of identifying the region when you need to do so. (listening to it works fine)
Naming is up to the recording engineer’s discretion. It’s good housekeeping prac-
tice to name regions uniquely for ease of editing, manipulation and reference
purposes, but unless your project involves a lot of editing, don’t go overboard.
Start time
This field shows the current time (SMPTE or BBT) of the left border of the region.
It’s dynamic. As you drag the region around or move its left boundary, the
displayed Start Time changes.
The time may be modified by editing the numbers in the field by any of the
standard methods - click and drag on the digits, or click to highlight and type in a
new number. When the entry is completed (press Enter or click outside the time
field), the time field and the region start point are updated.
Any region’s starting edge may be modified (or trimmed) by dragging the edge in
or out with the Hand tool. This changes the starting time of the playback without
changing the audio file on disk. If the entire region is dragged to another time, the
start time follows along.
End Time
This time field works exactly like Start Time, but on the right-hand end of the
region. It is edited in exactly the same manner as Start Time.
Region Length
This time field displays the difference between the Start and End Times, saving
you the trouble of doing the arithmetic (we know you don’t have six fingers). It’s a
handy reference for checking length before performing region looping operations,
pasting into tight crevices, or for finding out if that 30 second spot is short
enough. Since this is an absolute time display, it remains in SMPTE format
regardless of the time format selected for other time displays. It can be edited in
exactly the same manner as Start Time. Editing the Region Length is functionally
equivalent to editing the End Time.

Fade In and Fade Out
Fades, both Fade In and Fade Out, are tools that ramp the region volume from
zero amplitude up to unity gain amplitude (Fade In) or from unity gain down to
zero (Fade Out). Any time the fade length is greater than zero, the associated end
portion of the region (start, end, or both) will be displayed in the track area with a
different background color. This is the area over which the fade takes place. A red
line through that fade region represents the relative change in amplitude within
the fade region. The amplitude of the waveform follows the fade curve.
When the Hand tool is
placed on the inside
boundary of a fade region
and above the centerline of
the waveform display, the
“hand” changes to a “fade”
tool. This fade tool, which
looks like a quarter-circle,
is used to drag the edge of
the fade region to extend or
reduce the fade length.
Fade length can also be
adjusted “by the numbers”
by opening the Region
Editor window and editing the Fade time fields.
Obviously a fade time cannot be longer than the total region length, however a
fade can extend over the full length of the region. Fade In and Fade Out interact,
however, and one will push the other over to make room if they begin to overlap.
There are three selectable fade curves, which determine the rate of change of
volume over the fade time - slow, linear and fast. Your ears will tell you which one
works best for the application. Adjusting fades is best done interactively – listen,
adjust, listen again. You may find it convenient to set up a loop around the fade
region so that you can fine tune while listening.
Envelope Active
The Envelope ACTIVE button enables the volume changes you have made with
the Node tool. When Envelope View (Options\View Envelopes) and Envelope
ACTIVE are both turned on, the volume envelope is indicated by a yellow line in
the region, and the audio volume follows that envelope. If the ACTIVE button is
off, volume changes will not be heard.
The default envelope level is unity gain, at approximately 75% of the full region
height. Although there’s no calibration scale for the volume envelope, clicking on
the volume envelope line with the Envelope Node tool opens up a readout window,
showing the gain at that point. Full scale represents a gain of 6 dB, while the
bottom of the region is full off.
IMPORTANT: Even though View Envelopes is turned on, the volume envelope line
will only be displayed if the envelope has been made ACTIVE in the Region Editor
window or the Options pulldown menu. Conversely, if the volume envelope is AC-
TIVE in the Region Editor and View Envelopes is not turned on, the envelope will
not be visible in the region, however the volume will follow the (invisible) enve-
lope. Hence, it’s possible to have volume changes occurring within a region that
you don’t see on screen. If you work with volume envelopes, it’s best to leave
View Envelopes on.

Region Looping
The Loop Region feature allows you to loop a specific portion of a region for
repetitive playback. This Loop function is usually used to create rhythmic
patterns, but may be used to create effects such delay repeats.
Region Loop mode is toggled either by clicking on the LOOP button in the Region
Editor window or by right-clicking in the region and selecting Loop from the pop-
up menu.
The length of the loop is equal to the region length displayed on the screen and in
the Region Edit window. Trim the length if necessary before looping the region.
When Loop mode is enabled, the region selected for looping may be stretched out
to repeat for any desired length of time. Regions can be looped in either direction
by pulling the region start or end points. The number of repeats need not be an
exact multiple of the loop length. It’s possible, for example, to have three and a
half loops.
Small tick marks on the region base and top delineate the start and end of each
repeated section within the extended loop. Multiple regions may be selected and
looped at one time, for up to 24 tracks of playback. If Loop is enabled by right-
clicking on one of a group of selected regions, they will all loop.
Region Lock
This Region Lock function disables editing or moving a region, but a locked region
can be copied. A selected region can be locked by right-clicking in the region and
selecting Lock from the pop-up menu, or by clicking on the LOCK button in the
Region Editor window The background of a locked region turns dark gray to
indicate its locked state.
Region Lock status is a toggle. Unlock a locked region by clicking on the LOCK
button in the Region Edit or uncheck Lock from the right-click pop-up menu.
NOTE: Locking does not prohibit recording over a region. If you want to protect a
region from recording, move or copy it into another track or virtual take.
