Doepfer - A-144 morphing controller

  • $90.00


Module a-144 is a control voltage modifier that is used in combination with the voltage controlled mixer a-135-1 and a-135-2 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-135-1 /a-135-2 one obtains a fading over of the four 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 , e.g. morphing between the 4 waveform outputs of an vca (sawtooth/ rectangle/ triangle/ sine) or the 4 filter outputs of the multimode filter (lowpass/ bandpass/ highpass/ notch) or the 4 filter outputs of the (6/12/18/24db) to obtain a filter with voltage controlled slope.

inputs: cv in
outputs: cv out 1, 2, 3, 4
controls: manual morphing, cv attenuator.

this module has a maximum current draw of 30ma. it requires 8 te/hp worth of space to fit in a eurorack frame.
