Polyend - Poly


Poly is a clever MIDI to CV interface with eight channels and a note range of twelve octaves. The module can receive MIDI data from DIN equipment, a computer / smartphone and an USB controller. On the output side, there are three CV connectors and a gate socket per channel. Thanks to intelligent voice management, polyphonic setups can be patched to any desired extent without having to change settings on the module. On top of that, there are several modes of operation for setting up polyphonic or multiple monophonic patches. – How about using the Poly to control six drum voices, a bass line and a lead?



The Poly module comes equipped with three MIDI inputs, in detail:

  • A DIN connector
  • An USB-A port with 5 V power supply for connecting a MIDI controller
  • An USB-B port for connecting a computer, tablet or smartphone

The module's eight output channels feature four outputs each. The connectors emit voltages in the range of 0 V to +12 V. – Therefore, the Poly can play oscillators in a range of twelve octaves. In detail, the following connectors are available:

  • Pitch (1 v / octave)
  • Velocity
  • Modulation (A MIDI CC number in between 0 and 127 can be chosen via a DIP switch on the circuit board.)
  • Gate

A switch at the front panel allows users to choose between three modes of operation:

  • First (Polyphonic mode, the voices are always played from the first voice onwards.)
  • Next (Polyphonic mode, the voices are played alternately.)
  • Channel (Multi mono mode, MIDI channel one to eight or nine to 16 are used. The configuration is done via a DIP switch on the circuit board.)

An important feature of the Poly module is its intelligent voice management. – Only voices with the gate outputs patched are used. Therefore, it is not necessary to change any settings when, for instance, switching from a four-voice to an eight-voice patch. – A very comfortable solution.

Poly is compatible to the MPE standard (Multidimensional Polyphonic Expression).
