Chapter 2: Descriptions
The Main Interface
Here we discuss getting around the GUI. More detail on parameters follows
later in the manual.
1. Host Area - This will be displayed differently for each host program. In this
case, the host area of Cubase SX is shown.
2. Visualization Area - Here you can see at a glance information about the current
preset. Each head represents an enabled voice. Click on a head, and you can drag
the mouse to change the harmony interval of each voice (although not in Notes and
Notes 4CH modes because harmony intervals in these modes are determined by
incoming MIDI note messages). Gender is represented by the apparent male, or
female characteristic of each voice. The soundwaves emanating from the heads
show both level, and pan position. The lower part shows text representing each
harmony interval, or MIDI note depending on the current harmony mode.
3. Tab Editing Area - This is composed of 4 tabs containing parameters that
are grouped by function. Generally, each voice has its own vertical column of
settings. The slider on the right side of this window can be used to reveal more
parameters if they exist.

The Main Interface (cont.)
4. Preset Area - This drop down menu displays the included factory presets.
This menu is provided in case the host application does not have a preset menu
of its own.
5. Wet/Dry Mix, and Pan - There is an optional dry path through the plug in for
times when you use Harmony4 as a channel insert. Note that when used as a
stereo insert plugin, only the left channel of the audio track will be as input to
Harmony4.
6. Harmony Mute - Pressing this button will quickly turn the harmony voices off.
7. Musical Info/Various - Each harmony mode has different requirements in
order to make the voices produce musical sounding harmonies. See the
“Control Tab” section later in this manual for each harmony mode’s
requirements. The parameters in this area will differ depending on which mode
is selected. You can tell at a glance the harmony mode of the loaded preset,
and which type of musical input you need to provide.
8. Meters, and In/Out Levels- The upper meter shows the current pitch
recognized from the input voice. The pitch meter shows note, octave information
as well as the meter that shows whether the input note is sharp, or flat. This
meter shows +/- 50 cents. The lower meters display in/out levels. You can make
adjustments by clicking, and dragging the arrows.

The Voices Tab
The Voices Tab allows editing of settings you need most for each harmony
voice. The number of parameters differs depending on the harmony mode.
Level
Here you can mix the relative levels of each of the four voices. There is also an
"Off" value which will disable any voice. Note that turning all four voices on at
0dB (full) may produce overload. If this occurs, you can either reduce the input
level with the IN slider, or reduce the level of each voice.
Voicing (editable in Shift, Scale, and Chord Modes)
The Voicing parameter allows you to arrange the intervals of your four singers
above, and below the lead singer. Voicing works slightly differently in each
harmony mode.
In Shift Mode, the Voicing values range from -24 semitones to +24
semitones in a fixed, non-diatonic interval relative to the input melody.
In Scale Mode, the Voicing parameter specifies a diatonic interval relative
to the input. The range is -2 octaves to +2 octaves. For example, a setting
of +3rd will result in a harmony voice a third above the input voice, which
could be major, or minor depending on the current Key, and Scale settings.
In Chord Mode, Voicing determines a more general relation of the harmony
note to the input note. The harmony intervals always relate to the chord of
the incoming MIDI notes. A setting of "Up1" generally places the harmony
voice a third above the input voice.
In Notes, and Notes 4CH modes, the Voicing parameter is not shown, or
editable because intervals are the same as the incoming MIDI notes.
Pan
Each harmony voice can have its own stereo pan position. Spreading the
harmony voices within the stereo field can help de-couple the harmony voices
from the input voice, resulting in more natural sounding harmonies. Left = “-”,
Right = “+”
Gender
This parameter shifts the formants (often called the gender) of the harmony
voices. Use it to alter the character of the voice ranging from -50 (a big person
with a deep, resonant voice) to 0 (no change) to +50 (mice/alien sound).
Note Source, and Input Note (Only available in Scale Mode)
These parameters help you to create custom scales for times when the lead
voice melody, the harmony voice(s), and the musical accompaniment don’t
sound correct on certain notes. You can edit the individual harmony notes of all
four voices (if they are all enabled) for each input note.
Harmony4 page 9

When Note Source is set to "Manual", you can select the Input Note with your
mouse. When Note Source is set to "Sung", the Input Note is determined by the
pitch of the singer.
Output Note
Each of the 4 harmony voices can produce a different harmony note for every
given input (sung note). Use these parameters to set the desired output note for
each enabled voice.
The Humanize Tab
TC-Helicon’s Humanize settings make the harmony voices sound more natural,
or even wildly effected if you prefer. You can select a pre-programmed
Humanize style, or start with the Off style, and experiment with each parameter.
Style
This parameter contains preset values for all the parameters in the Humanize
block. It provides quick access to different qualities of performance.
Portamento
Portamento sets the time in milliseconds to reach a target note when a harmony
voice changes pitch.
Smoothing
This is most effective in Scale mode. At Smoothing settings near zero, the
harmony voices will sound in tune even if your lead voice is a little out of tune.
In this case, the pitches of the harmony voices are pitch-corrected to a
chromatic semitone scale. Settings near 100 allow the lead singer to float
between pitches with the harmony voices following closely.
Detune
With the Detune Parameter, a tiny, fixed amount of pitch shift is applied uniquely
to each of the harmony voices. This creates a thicker, chorus-like effect when
applied to harmony voices set to similar pitches.
Pitch Randomize
Small amounts of this parameter apply a unique, moving pitch shift to each
voice that is derived from the study of human singing. It is used to remove the
sometimes mechanical sound of perfectly in-tune harmonies.
Time Randomize
No group of singers is able to start their harmony notes at the exact same time.
Lower values of this parameter create slight timing differences to the onset, and
sustained portions of each harmony note. This feature greatly increases realism
when the harmony voices are panned in stereo. Also note that sometimes
breathy consonants in the lead voice can create a slight flange effect when
mixed with the harmony voices. Adding Time Randomize can help reduce this.
Harmony4 page 10

Vibrato Style & Amount
A unique modeled vibrato based on the analysis of human singers can be
added to each harmony voice using a combination of these two parameters.
When Style, and Amount are chosen, vibrato occurs when the pitch of the lead
voice has settled momentarily. This more closely simulates human singing.
Vibrato may not occur if the lead voice melody is changing quickly.
The styles are randomized so that they sound slightly different on each voice
even when the same style is chosen for all. Mixing different styles can create a
very realistic sounding vocal group.
Scoop Style & Amount
The Scoop parameter adds a brief pitch envelope to the onsets of the harmony
notes, further disconnecting the harmonies from the lead. Select a style, then
use the Amount control to determine the shift range of the scoop
The Control Tab
The Control Tab is used to configure parameters that relate to the different
harmony modes. Depending on the mode, different parameters are available. A
brief description of each harmony mode follows here with more detailed
discussion following in Chapter 3.
Mode: Shift
Shift Mode is best used for doubling, and special FX. Shift is the most basic
mode of operation for the Harmony Block. The harmony voices can be shifted
away from the input note in semi-tones.
Mode: Scale
In Scale Mode, harmonies use key, and scale information to create musically
correct, diatonic harmonies. Scale Mode harmonies are more parallel than
Chord Mode harmonies. To overcome situations where the harmony interval is
incorrect for one, or two sung notes, the custom scale editing parameters may
be used. Refer to Appendix: Scale Types, and Voicings Table
Mode: Chord
In Chord Mode, musically correct harmonies are produced by chords
recognized from the incoming MIDI notes.
Mode: Notes & Notes 4CH
In this Mode, incoming MIDI notes determine the pitches of up to four harmony
voices. When "Notes" is selected, a single MIDI channel controls the 4 harmony
voices. When Notes 4CH, or “Notes Four Channel” is selected, each harmony
voice is assigned a unique MIDI channel in the Setup tab which has many
benefits including:
1. the ability to use unique pitch bends on each channel
2. full stability of panning, and gender assignments for each voice.
Harmony4 page 11

To take full advantage of this mode, you will need to have 4 tracks of MIDI data
on separate channels driving Harmony4.
Key & Scale (available only in Scale Mode)
Use these parameters to set the key, and scale type. The scale defines the map
for how the harmony voices will react to the input pitch. Available scales are
Major/Minor 1,2, and 3. Custom scales can be created for situations where the
predefined scales don’t produce the desire results. Refer to Appendix: Scale
Types, and Voicings Table
Attack and Release
Available only in Chord, and Notes Modes, these parameteres set the envelope
attack, and release times for harmony voices. Using these parameters can
make entrances, and exits of the harmony notes softer, or harder. This function
works when Latch is "Off", and MIDI notes are being received.
Latch (available only in Chord, and Notes Modes)
When enabled, the last chord remains active after the notes have been
released. When disabled, harmony output stops when MIDI notes are released.
In notes mode, the number of notes played must equal the number of harmony
voices enabled for any voices to be triggered.
Bend Range
You can define how far the harmony pitches are shifted when you move the
pitch wheel on your MIDI keyboard. The values go from 0 to +\- 24 semitones.
Tuning
There are three micro tuning options for all modes except Notes, and Notes
4CH.
Equal Tuning uses approximations for the tuning of each note, allowing you
to easily alter the key of your music without re-tuning your instruments. This
is the same way synthesizers are tuned. Most non-digital instruments are
tuned this way.
Just Tuning maintains the exact relative ratios between pitches,creating
perfect harmonies. Just Tuning will sound natural the majority of the time.
Barbershop Tuning differs from Just Tuning only in Chord Mode, and is
best used for a cappella applications.
Hold
This control engages the Harmony Hold feature. When set to "On", Harmony
Hold freezes the harmony voices while allowing the lead voice to ad lib over
top. When a preset is stored, the parameter will always be saved as "Off". The
Signal will not be held until a stable pitch is recognized.
Hold Release
Sets a fade-out time for the hold feature when returned to the "Off" value.
Harmony4 page 12

Root, and Chord (available only in Chord Mode)
Use these parameters to set the chord root (e.g. C), and chord type (e.g. major
7). The chord defines the allowable notes for the harmony voices.
The Setup Tab
When using the two modes that require MIDI input, Notes, and Chords, it is
essential to match the MIDI settings of Harmony4 to those of your DAW’s MIDI
track for controlling harmony.
Harmony V1(All) Channel
The MIDI channel for notes, and sustain pedal information must match the
channel of the transmitting keyboard controller, or sequencer MIDI track. Chord,
and Notes modes (but not Notes 4CH) require only the Harmony V1(All)
Channel be set to match your controller.
The other three channel assignments only apply when using Notes 4CH mode
where each voice has its own channel assignment. The “Vn” nomenclature
denotes each edit field as the channel setting for Voice 1 through 4.
Harmony V2/ V2 / V3 / V4 Channel
In Notes 4CH mode only, these settings determine which channel controls each
single voice.
Notes Transpose
In Notes mode only, this setting works in tandem with the Split Zone, and Split
Note settings to allow you to play high harmony notes on the lower section of
your keyboard, and vice versa.
Split Zone & Split Note
You can use these settings to isolate which section of your MIDI keyboard will
control Harmony4. This is mostly used when playing live with keyboard sounds
triggered from one side of the keyboard, and harmonies triggered from the
other.
Tuning Reference
If the vocal track that drives Harmony4 was recorded with a non-440Hz
instrument reference, you can use this setting to bring the harmonies into tune.
Bend Range
See the Control Tab description previous.
Harmony4 page 13

Chapter 3 - Producing Harmony
Harmony Modes Background
A quick description of why the harmony modes are required is that they help
Harmony4 “sing the right notes”. Each harmony mode requires different input
from you and is capable of producing different harmony sounds. We will use a
little allegory to explain.
When you and a fellow musician get together to play and sing, typically some
musical information is passed from one to the other before commencing the
song. You do this in order to make sure the music sounds pleasant and not
discordant. The information can be as simple as the name of a song you both
know, a musical key, or even pointing out the chords on your instrument. In this
respect, Harmony4 is similar. You will need to share some musical information
in order for it to do its job properly. The ways in which you communicate this
information to Harmony4 are through the “harmony modes”.
Like your friend in our analogy, Harmony4 has intelligence that can contribute to
making good music. You can choose to use this intelligence, or not depending
on the chord structure of your song and the harmony lines you have in mind.
You make this choice when choosing presets to produce harmony in your song.
The factory presets are organized on the basis of the four harmony modes:
 Scale
 Chords
 Notes
 Shift.
The “intelligent” harmony modes, Scale and Chords, calculate a harmony map
with the following inputs from you:
1. The note the lead vocal is singing at any given moment;
2. Either the key and scale you’ve set at the beginning of your song (Scale
mode);
3. or the chord root and type interpreted by Harmony4 from incoming MIDI
track (Chords mode).
The map has an output note associated with every input note. This creates a
harmony melody that moves with your lead melody while generally sounding
harmonically correct with your accompaniment.
The non-intelligent modes, Notes and Shift, each have unique requirements so
we will deal with them individually:
The Notes harmony mode requires a MIDI keyboard, or other MIDI source to
Harmony4 page 14

dictate to Harmony4 what harmony notes you’d like to hear. Once a harmony
note, or notes are held down on your MIDI keyboard, or MIDI track, this is
where they will stay regardless of your changing vocal melody.
Shift mode shifts the pitch of the lead melody by a fixed interval. This is most
useful for doubling, special effects, or Gothic-sounding 5ths.
A Comparison of the Harmony Modes
The following table gives an overview of the plusses and minuses of each
harmony mode.
Getting Set Up
1. Prepare your DAW and PowerCore hardware for a new session. Turn on your
computer, run the host program and ensure that any external PowerCore unit(s)
are powered on.
2. Connect a MIDI keyboard to your computer and set your host program to
route the MIDI to Harmony4, or create a MIDI track in your host application.
3. Import an audio file containing a dry vocal performance into your session.
Notes concerning input files:
 The vocal track driving Harmony4 can be mono, or stereo. In the case
of it being stereo, only the left channel send is sent to Harmony4. See the
Insert, or Auxiliary Send? note below for more information on mono/stereo.
 There should be as little as possible pitched instrument, or other vocal
leakage onto the main vocal track. Increasing leakage compromises the
harmony quality.
Harmony4 page 15

 Any equalization of the send to Harmony4 should be removed. You
can add EQ after the plug-in, if required.
 While Harmony4 has excellent pitch detection, it may have trouble
finding a pitch in growled, or extremely raspy voices.
4. Create a send bus from the audio track to Harmony4. This will be handled
differently in the various DAW programs so consult the manual that came with
your DAW if you haven’t done this before. You can confirm that audio is
reaching H4 and is being processed by checking the Input and Output meters.
Insert, or Auxillary Send?
 While you can run Harmony4 as either an insert, or auxiliary send
plug-in, typically, it’s best to run it as an auxilliary send effect. This allows
you to process the lead and the harmony voices separately. Also, you will
be able to use the track faders in your DAW to control return levels of lead
and harmony independently. When using this method, ensure that no other
tracks are inadvertently sending to Harmony4 on its assigned aux send
bus.
 You can use H4 as an insert if you do not have enough aux sends
available in your DAW to drive Harmony4, or if you don’t need to return the
dry portion of the vocal track to the mix. It is not advisable to insert
Harmony4 in a stereo track because the dry return to the mixer will be
heard on the left channel. Note that using Harmony4 as an insert requires
that you control wet/dry mix within the plug-in as opposed to the track fader
controls in your DAWs mixer.
5. You can confirm that Harmony4 is receiving MIDI note information by loading
a Notes mode preset e.g. Notes In Stereo and observing note names in the
visualization area as you play your keyboard, or playback a MIDI track.
Checking Out The Harmony Presets
Now that you’re setup, you can start producing harmony! If you are familiar with
TC-Helicon harmony products you can proceed directly to the presets dedicated
to the harmony mode of your choice and experience the results.
1. If this is your first time creating virtual harmonies, start by loading the first
preset in the factory preset list. The first group of presets are based on the
Chords harmony mode so get ready to play chords on your MIDI keyboard, or
playback a MIDI track in time with the song’s chord changes.
2. Press Play and confirm all of your audio paths are correctly set. You should
hear a mix of the lead voice and the harmony voices and see metering
indications in your track meters. Until you play the keyboard, or MIDI track, the
harmonies won’t follow the song but this is OK while you’re making sure the
audio paths are correct.
Harmony4 page 16

You may want to record a scratch MIDI chord track in your host sequencer in
the song sections where harmony is required so you can try the different
Chords presets without having to play at the same time.
3. You can now listen to how the different Chord presets sound as the song
plays. At this point you can also start learning about editing. A good place to
start is with parameters in the Voices Tab. Here you can move the Voicing up
and down and hear the effect of different Gender settings on each voice.
4. Once you’ve experimented with the Chords mode presets, you can check out
the presets built on Notes mode. You’ll need your MIDI keyboard, or MIDI track
again but this time, instead of simply playing chords, you also have the option of
playing melody lines, or holding static notes.
Again, it will help if you create a scratch MIDI track with some harmony lines
so you can sample the different Notes presets.
One of the Notes mode presets is called MIDI 4 Channel. To hear this preset
correctly, you will need to record up to four MIDI tracks on different MIDI
channels each with a mono melody line. The four MIDI channel assignments of
the tracks must match the assignments set in the Setup tab of Harmony4. It
sounds like a lot of work but this is arguably the most flexible and powerful
harmony mode so it is worth the extra effort to hear it. Be sure to try different
pitch bends on each channel.
5. Auditioning the Scale mode presets with your lead vocal track is much easier.
All you have to do is determine which Key and Scale matches your song, or
song section, and enter it when you load each preset. If the song chord
structure is fairly simple, one setting of Key, and Scale will sound wonderful.
What may happen though is that the harmony part will sound great for most of
the song, or section but when the accompaniment goes to a particular chord,
and the singer sings a particular note, the harmony at that moment doesn’t
sound musically correct.
When Scale harmony needs help, the beauty of DAW automation comes to the
rescue! Take note of where the harmony needs to be adjusted. Then loop this
section, and find a Key, or Scale combination that works for that moment. Now
automate a Key, or Scale edit just before that note, or phrase. Return to the
original Key, and Scale settings for the rest. You may have to do this at a couple
of places in your song but the often breathtaking reality of Scale mode
harmonies will make it worth the effort.
A table outlining the differences between the three Major, and three Minor
scales is in the Appendix. These scale modifications have been developed by
performing musicians to make Scale harmonies work for more songs.
6. Shift is the last harmony mode group in the factory presets. These are least
likely to produce what we call harmony but they can be useful for doubling, and
special FX. No input on these presets is required beyond loading the preset.
Editing the voicing parameters though will give you a good idea of what is
possible with this harmony mode.
Harmony4 page 17

If you’ve stayed with this text up to this point, you’ve received a good overview
of what Harmony4 has to offer. From this point onwards you can work with
presets in the harmony modes that suit your workflow best.

Chapter 4: Appendix
Troubleshooting
For the more extensive and up to date troubleshooting information please visit
www.tcsupport.tc
I don’t hear any harmony voices, but the input meter to Harmony4 shows
input level - nothing on the output?
There are several common reasons harmonies are not being produced when
the plug-in shows input level:
1. Harmony Mute is enabled: disable it to hear harmonies
2. A Notes or Chord preset is selected: make sure there is MIDI being sent
through the correct path in the DAW program
3. If MIDI is being sent, but there are still no harmonies: confirm that:
a) the MIDI channel for Harmony4 is matched to your track with MIDI
information. or;
b) the split point settings are allowing MIDI notes through
Why do my meters only show activity on the left channel?
If Harmony4 is inserted on a mono channel only the left side of Harmony4 is
used. For both meters to function, use Harmony4 on a stereo channel.
Sometimes I hear excessive sibilance when using Harmony4?
The harmony voices are pitch shifted and humanized versions of the input
voice. If there is sibilance on the original recording, that effect becomes more
noticeable with each harmony voice added. Try using Time Randomize = 10.
Additionally, consider using a de-esser plug-in.

The table at left illustrates the how the six scale types
differ. It shows the third and fifth intervals for input
notes in the key of C.
The bold line of notes at the top represent the sung,
or input note.
The symbol “nc” means no change, in that the harmo-
ny voice will simply stay on the previous note until the
lead voice changes to a non “nc” note.
