Module A-144 is an extension module for the Voltage
Controlled Mixer A-135
Controller that derives from a linear increasing control voltage at the input (0...+5V) four displaced
triangle voltages (0 bis +5 V). These voltages are
used as control voltages for the Voltage Controlled
Mixer to obtain a fading over (“morphing”) the four
A-135 audio inputs with only one control voltage fed
into the A-144 CV input.
Morphing
nual morphing control 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
signals in combination with A-135, e.g. morphing between the 4 waveform outputs of an VCO (sawtooth/
rectangle/ triangle/ sine) or 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
led slope.
