P401 Poly-4 MIDI Interface Classic Edition

4-Voice Polyphonic MIDI Interface

The P401 Poly-4 MIDI Interface adds four-voice polyphony to your modular system.

It has a wide range of functionality in a compact form, including note outputs (with normalled pitchbend) featuring precision 12-bit DACs with a typical deviation of only ±1 cent (±0.001V) over ten octaves. The range of each note output can also be offset using trimmers on the PCB as desired.

Other outputs per voice include 5V gate and 10V velocity outputs. There is also a 4 PPQN Clock (5V) output and 10V modulation wheel output included.

Various modes include polyphonic, monophonic and unison. Polyphonic and unison modes can be mapped to MIDI channels 1, 3, 5 and 7 using jumpers on the PCB. Monophonic mode outputs four separate voices to outputs 1, 2, 3 and 4 on MIDI channels 1, 2, 3 and 4 respectively, allowing for multitimbral capability.

Polyphonic mode has two voice allocation algorithms that can be assigned with a jumper on the PCB, including lowest note (featured on the original Prophet 5) and round robin, allowing for different tonalities to be achieved.

Finally, the note priority for monophonic and unison modes can be switched on the front panel between last, highest or lowest.
