MIDI connected to modular world

There are many great, functional MIDI tools and devices (DAWs, controllers, sequencers, keyboards etc.) and as many fantastic Eurorack modules. Polyend Poly seamlessly connects these worlds thanks to its multiple inputs and outputs.

The interface

Poly equips you with all kinds of MIDI inputs. Connect your computer, smartphone or tablet to its USB port, your class compliant MIDI controllers via USB Host, and all the other devices via the classic MIDI DIN port. A whole array of analog outputs give you the versatility to hook up loads of different types of modules. Eight rows of Gate, Pitch, Velocity, and Modulation let you freely control synth and drum voices.

MPE compatible

Polend created Poly to be compatible with MPE standard (Multidimensional Polyphonic Expression). MPE is a perfect match for the modulars.

Three modes, totally different possibilities

Depending on what you want to achieve, there are three modes you can choose from: First, Next and Channel. Both First and Next modes are perfect for building your unique polyphonic synthesizer. In Channel mode a DIP switch on the back panel lets you choose between MIDI channels 1-8 or Notes C-G that are directed to corresponding CV voices.
