MORPH 4
DIMENSIONAL MODULATION ARRAY

4 SIGNAL INPUTS
Connect your input signals to these sockets.
Input A has a +5 V normal, making it easy to use
Morph 4 to generate rather than process signals.
All other inputs are normalised from the
preceding one (A into B, B into C and C into D),
as indicated on the front panel, so the same
signal can be sent through multiple modulators.
Any kind of signal can be used: audio, CV or
gate/trigger.
5 LEVEL INPUTS
The level CV inputs provide linear voltage control
over the modulators. With the attenuator at
maximum, the response is 0 (−∞ dB) at 0 V, and
unity gain (0 dB) at +5 V. They can be made to
amplify when more than +5 V of CV is applied.
By default, these sockets are driven from the
triangular morph responses generated for each
modulator from its position and span
parameters. Plugging a socket into one of them
allows the corresponding modulator to be
controlled directly instead, overriding the morph
functionality.
6 POSITION AND SPAN INPUTS
Any voltage applied to one of these sockets is
added to the position/span set using the
corresponding modulator’s knob.
7 SIGNAL OUTPUTS AND LEDS
The modulated signals are available directly from
these output sockets.
The LEDs show the real-time output voltages,
lighting up red for positive and blue for negative.
8 LEVEL LEDS
These LEDs visualise the incoming level CV for
each channel, determined either by the morph,
position and span parameters or the signal
applied directly to the level socket, before any
attenuation by the corresponding level knob.
9 MORPH KNOB
The morph parameter is a kind of ‘macro control’,
affecting all channels simultaneously (except
channels where the level CV input is in use). How
the channels respond to different morph levels
depends entirely on their position and span
settings.
10 MORPH MODULATION INPUT AND KNOB
External modulation of the morph parameter is
possible using this input socket and polariser
knob. While the manual knob range is 0 to +5 V,
corresponding to the range of the channel
position knobs, external modulation can move
the morph value outside this range if desired.
11 SUMMING OUTPUTS
Two sub-mix outputs are available: one
combining channels A and B, and another
combining C and D. These are typically used for
(stereo) crossfading applications.
12 ADDER/AVERAGER OUTPUTS
These additional mixing outputs combine all
channels, useful for voltage controlled mixing
and scanning. They only differ in gain.
The adder output simply adds up all channel
output voltages at unity gain, most useful when
processing low-level signals.
The averager on the other hand lowers gain by
12 dB, avoiding clipping when processing
stronger signals.
13 MINIMUM/MAXIMUM OUTPUTS
The minimum and maximum output voltage
levels of the four channels are continuously
computed by analogue circuitry and made
available from these output sockets. They can
create surprising results for a wide variety of
input signals.
