Morphing Controller

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 VCO (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.

These merchants probably sell this module. Huh?
