Rossum Electro-Music MORPHEUS User manual

MORPHEUS
Stereo Morphing Z-Plane Filter
Thanks for purchasing (or otherwise acquiring) Morpheus. This guide will get you up and
running with a minimum of fuss. However, given Morpheus’s unique features, you should
really check out the full owners manual at:
www.rossum-electro.com/support/documentation
Installation
While all Rossum Electro-Music modules
are protected against damage to the
module or your system from reverse
polarity, care should still be taken to
connect the power cable correctly.
Plug the 16-pin connector into the header
on the rear of the module such that the
red stripe on the cable (the -12V side) is on
the same end of the header as the “Red
Stripe (-12V)” text on the PCB.
Morpheus requires, at most, 135mA of
+12V and 25mA of -12V.
We have included both M3 and M2.5 (for
vector rails) mounting screws. Use what
fits your system.
If rack rash is of concern to you, use the
included nylon washers when mounting
Morpheus in your case.
Be Sure You Have the Latest
Firmware
If we’ve released an updated version of
firmware after your module was shipped
to your dealer, you should update to that
latest version before proceeding.
To check:
> Press and hold the Edit Filter button
until the Utilities screen appears. At
the bottom of the screen you’ll see the
current installed firmware version.
> On the web, go to the Downloads
tab at www.rossum-electro.com/
products/morpheus/ and note the
latest firmware version.
> If it’s the same as the version in your
module, you’re good to go. If not,
follow the instructions there to update
your module.
Getting Familiar
The best way to get a quick idea of what
Morpheus can do is try out some of the
included factory filters. There’s a filter for
each of the 288 Z-plane cubes. You’ll find
a current list with descriptions of them in
the manual.
To most eectively audition the filters, set
your Morpheus up as follows:
> Patch an audio source (VCO, noise
source, sample player, or whatever)
into one or both (if it’s stereo) of the
Input jacks.
IMPORTANT: The audio source
should be as rich in harmonics
as possible to give Morpheus lots of
raw material to deal with. In fact, entire
mixes make great program material.
> Patch individual modulation sources
into each of the attenuverted
Frequency, Morph, and Transform
inputs. Examples are envelopes, LFOs,
random voltage sources, or (shameless
plug) Rossum Electro-Music Control
Forges and/or Satellites.
Check out the other side of this card
for details on selecting and
loading filters.

Functional Overview
www.rossum-electro.com
Controls
FREQUENCY, MORPH,
TRANSFORM
Control the point in 3D filter space
that defines the interpolation
between the 8 14-pole filters.
FREQ CV, MORPH CV, TRANS CV
CV inputs into attenuverters.
(Transform controls Distortion on
some filters.)
FULL LEVEL
Unattenuated Frequency CV input.
FILTER EDIT/SAVE
Create and save up to 1000 custom
filters.
FILTER SEQUENCER
Allows stepping through up to 200
user-defined series of filters under
trigger control or manually via the
encoder. Also useful for creating
thematic filter sets for easy access
during performance.
L/R INPUTS
The signal(s) to be filtered go in here.
Morpheus is DC coupled, so you
can also filter CVs with most cubes.
L/R OUTPUTS
Sound comes out here.
Selecting Filters
To select from among all of your saved
filters, first make sure that the Filter
Sequencer is O. Press and hold the
Select Sequence button to toggle it on
and o.
With the sequencer o, turning the
encoder will scroll through all existing
filters. When you see the one you want,
click the encoder’s switch to load it.
If you change your mind before clicking,
scroll back to the currently loaded filter.
You’ll see the Load Filter box disappear.
For even more fun, press and hold
the encoder — filters will now load
immediately as you turn it.
When the Filter Sequencer is On, turning
the encoder will only display and select
filters in the currently loaded sequence.
This is useful for manually controlling
a Filter Sequence as well as using the
sequencer to create sub-sets of filters for
easy access in specific situations.
As shipped from the factory, Morpheus
contains a series of sequences that
subdivide the filters by basic function.
Loading one of those sequences allows
you to select among only that filter type.
