"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."
