Doepfer A-144 Morphing Controller

Doepfer A-144 Morphing Controller was designed to aid some of the voltage controlled quad modules in your eurorack modular system. This module adds 1+3 triangle waves after one another. Once a modulation waveform reached its peak, the next starts fading in. Ideal for animating any patch or fade between modulation or audio signals when plugged to a VCA.

Doepfer A-144 Morphing Controller was designed to aid some of the voltage controlled quad modules in your eurorack modular system. This module adds 1+3 triangle waves after one another. Once a modulation waveform reached its peak, the next starts fading in. Ideal for animating any patch or fade between modulation or audio signals when plugged to a VCA.


Module A-144 is a control voltage modifier that is used in combination with the voltage controlled mixer A-135 in the first place. From a linear increasing voltage at the input the module derives four displaced triangle output voltages. When these 4 outputs are connected to the four control voltage inputs of the A-135 one obtains a fading over of the four A-135 audio inputs ("morphing").

The Morphing can be controlled manual and modulated with an external control voltage (e.g. from LFO, ADSR, Random, MIDI-to-CV, Theremin, Light-to-CV, analog sequencer) with attenuator. Applications: voltage controlled morphing of 4 audio signals in combination with A-135, e.g. morphing between the 4 waveform outputs of an VCA (sawtooth/ rectangle/ triangle/ sine) or the 4 filter outputs of the multimode filter A-121 (lowpass/ bandpass/ highpass/ notch) or the 4 filter outputs of the A-105 (6/12/18/24dB) to obtain a filter with voltage controlled slope. When an audio source (e.g. sawtooth, triangle or sine of a VCO) is used as CV input signal the module can be used also as Waveshaper.

The four A-144 outputs can be mixed e.g. by means of a Polarizing Mixer A-138c with adjustable level and polarity. Inputs: CV In Outputs: CV Out 1, 2, 3, 4 Controls: Manual Morphing, CV attenuator For more detailed information please look at the English user's guide.

Technical Note: In principle the module is nothing but four sawtooth-to-triangle waveform converters (the same as used in the A-110-1). Each converter has a different DC offset to obtain the described behaviour of the four CV outputs required for the morphing function.
