For each voice a pitch control voltage (1 volt per octave standard to control VCOs), a gate output (to control envelope generators) and two additional control voltages (CV2, CV3) are available. The two additional CV outputs can be controlled by Midi velocity, volume, modulation, pitch bend, after touch or free assignable Midi controllers.

This module can work in different modes. In the four voice monophonic mode you can control four monophonic voices by four succeeding Midi channels. The four voice polyphonic mode is comparable but you can play it from only one Midi channel. In the two voice polyphonic you can control two monophonic voices by one Midi channel. There is also a mode called unisono where all the voices receive the same control voltages. With this mode, you don’t need multiples to control your four oscillators and VCA’s.

The mode is selected by means of momentary switches and is shown in the LC display. Certain parameters of each mode can be edited (e.g. the midi channel(s), the midi reference note for 0V CV, assigned controllers for CV2 and CV3). The parameter values (e.g. midi channels) are shown in the display and can be modified by means of the momentary switches. In Play mode the LEDs of the first four switches display the gate states.
