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. 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

We are huge fans of MIDI and its vast possibilities. That's why we created Poly to be compatible with MPE standard (Multidimensional Polyphonic Expression). We believe that 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.

Poly Tutorial by Once upon a synth

The Poly allows you to use your digital gear like a DAW, drum machine, keyboard, iPhone, etc to control your eurorack modules. The "polyphonic" part means that you can play chords and assign each note of the chord to a different oscillator for example. There are 8 different channels, each with gate, pitch, velocity and modulation jacks.

“The Polyend Poly Module has reconfigured the way I use my modular system. All three modes work exactly how you would imagine. Impressive!”
Jimmy Edgar
"When I saw Poly from Polyend I was happily shocked because it was exactly what I was looking for."
Robert Lippok
"This module has the potential to refresh the way you look at the classic music tools, various MIDI devices or applications. It breathes a new life into my modular synth environment."
Michał Wolski
"I am loving both the Seq and Poly, this couple is absolutely gorgeous and insanely fun to use."
Richard Devine
"Perfect product, just love it! The Poly is ridiculously simple to set up (remember to set the switches the way you want before putting in the case!) and you get 8x4 channels (I feel confident saying that’s enough for my setup)! The ability to use a step sequencer like Numerology or just record (and edit) midi clips in Bitwig (or another daw), including harmonies, rhythmic counterpoints, polyrhythms, morphing, pattern change and unlimited memory, is a game changer for me personally. It’s not flexible in its routings, so perhaps there are better options for others and doesn’t send audio rate signals obviously ... but for me simple was exactly what I needed to trust computer/modular interaction again. Great module!! Makes everything around it better if that’s the way you like to work. And it also arrived from Poland three days after ordering in New York!."

“The Eurorack market offers plenty of MIDI to CV modules, but last year, when Polyend announced Poly we were immediately hooked. It’s not easy to find an 8-channel polyphonic (hence the name) MIDI to CV converter, that’s super easy to use (no menu diving!), with MIDI Din, USB and USB Host capability (+ MPE support)! As you would expect, Poly works great with Polyend’s own Seq sequencer, but thanks to its nifty features, we think this module should also be on the radar of any Eurorack user looking for multichannel MIDI-CV converters. Polyphony is (slowly) getting more popular in the Eurorack world, and Poly is probably the easiest entry point for these new sonic explorations. Also, Poly supports MPE controllers (such as the ROLI Seaboard Rise, Linnstrument, etc.), which is a big plus in our book. Adding an expressive controller like the ROLI Seaboard Rise to a Eurorack setup can make quite a difference. That said, the cool thing with POLY is that it’s a pretty versatile tool and can also breathe new life into your pieces of gear that were collecting dust. Last but not least, Poly can be an ideal bridge between your modular system and your DAW of choice. You can, for instance, go crazy sending modulation and automation messages to various modules. Needless to say, such a straightforward module comes with an inevitable trade-off between ease of use and features."
