The Quad Midi interface module is a very flexible yet affordable MIDI/CV interface which can be up to four voice polyphonic. You can use it as four independent interfaces or in a mixed mode with simultaneous monophonic and polyphonic modes.
Each of the "output channels" has a CV output with 1V/octave, a gate output and two further control voltage outputs for MIDI controllers like modulation wheel and pitch bend wheel. The output channels can be combined arbitrarily with each other or used totally independent with different MIDI channels. Combined output channels can be unisono, monophonic with rotating voice assignation or polyphonic.
There are four clock divider outputs that convert incoming MIDI clock signals as analog gate voltages. A reset output allows e.g for keeping step sequencers (with an according reset input) by MIDI start/stop commands in sync.
An important part of the concept is the simple use of all parameters without a display and complicated menu structures.
- pitch-CV: 1V/octave
- Gate voltages: 10V
- CV1, CV2: 0-5V (or -2,5V..+2,5V with pitch bend)
- legato function switchable per output channel
- clock outputs (10V): 1/4, 1/8, 1/16 and 1/8T (can be doubled)
- RESET output: 10V at MIDI STOP, 0V at MIDI START or CONTINUE
- WIDTH: 24 HP
