MORPH 4

DIMENSIONAL MODULATION ARRAY

INTRODUCTION

Modulation is the core concept of modular
synthesis: parameters changing over time,
adding movement and musical interest to what
would otherwise be merely static sounds. Being
able to control the amplitude of signals
throughout a patch is therefore essential, and
one can never have too many voltage controlled
amplifiers (VCAs).

Designed as a fully-featured modulation hub for
Eurorack synthesisers, Morph 4 takes the basic
concept of the multi-VCA module to the next
level.

Four linear amplitude modulators are controlled
by a master ‘morph’ parameter. The response of
each modulator to this parameter is completely
variable, both manually and under voltage
control, and can be overridden if desired. Each
response is triangular, with the ‘position’
parameter setting the maximum point along the
morph axis, while ‘span’ determines the width of
the triangle’s base.

CONTENTS

In the Morph 4 box, you’ll find:

 Product card, stating serial number and

production batch.

 16-to-10-pin Eurorack power cable.
 Mounting hardware: two black M3 x 6 mm

hex screws, two black nylon washers and a
hex key.

 The Morph 4 module itself, in a protective

cotton bag.

If any of these items are missing, please contact
your dealer or [e-mail].

In addition to separate signal inputs and outputs,
a variety of combined outputs is available as well:
A+B, C+D, add (unity gain) and averaging mixes,
and instantaneous minimum and maximum.
Input normalisation makes it easy to send the
same signal to multiple modulators, while
output and modulator response LEDs provide
essential visual feedback.

The combination of master control, fully flexible
modulators and multiple combined outputs
creates a module truly embodying the spirit of
‘patch programmable’ modular synthesis. Use
Morph 4 as a voltage controlled mixer, dual
crossfader, dual panner, interpolating scanner,
interpolating distributor, quad VCA,
quadraphonic controller, slope modifier, rectifier,
complex waveshaper or something in between
any of those—the choice is yours.

CONTROLS & CONNECTIONS

1 LEVEL KNOBS

The level knobs are control voltage (CV)
attenuators for the modulator level inputs,
determining the gain for each modulator.

2 POSITION KNOBS

Each modulator by default responds to the
morph parameter in a triangular fashion. The
position parameter sets the location of the
triangle’s peak in relation to the morph axis. For
example, if a position knob is set to the centre
position, that modulator will reach its peak
response when the morph knob is centred as
well (assuming no level CV is applied).

3 SPAN KNOBS

The width of the base for each modulator’s
morph response triangle is set by the span
parameter. For example, a small span means the
modulator will be fully closed for most morph
values, except for a small range around the peak
position.
