Play Your Studio As One
A Polyphonic Voice Distributor App for Mac.
Polymer lets you play your monophonic synths together, like they're all part of some giant mutant polysynth. And it operates via plain old MIDI, so it's compatible with almost anything — modulars, samplers, even virtual instruments.
That's just the tip of the iceberg: alternate notes between different synths in monophonic sequences, layer pads and leads to create songs without leaving the keyboard, or experiment with the outer limits of modular paraphony.
You’ll never look at your synth rack the same way again.
macOS 10.14 or later

Let's Break It Down
Intuitively work across multiple color-coded MIDI interfaces
Animated voice display makes it clear which synths are playing now
Versatile options — inspiration is always at arm's reach
Everything the 5-pin DIN touches is your kingdom.
Polymer works via the MIDI protocol, which has been around for over 30 years. Your favorite synth, sampler, or sequencer is probably MIDI-compatible!
Intuitively work with multiple interfaces.
Merge notes from multiple inputs. Play chords across synths connected to your computer via different MIDI interfaces.
Soft synths too!
Polymer is designed for controlling hardware synthesizers, but there’s no stopping you from controlling any soft synth that can be addressed via the macOS IAC Bus.
