Polyend / Poly 2

The ultimate MIDI to CV/Gate converter.
The world is filled with many excellent MIDI tools and devices (DAWs, controllers, sequencers, keyboards, drum pads, etc.) and a wide variety of amazing Eurorack modular synths. Poly 2 seamlessly bridges these worlds with its numerous inputs and outputs and configurable parameters.

The Interface
Connect your computer or smartphone to the USB port. Connect any MIDI class-compliant MIDI controller via USB host, or any other MIDI device via MIDI jacks. Numerous analog outputs provide the versatility to connect various types of modules. Adjust all necessary settings via the OLED display and easy-to-use menu system. Simply click the encoder to set, save, and load parameters.

Excellent Compatibility
To ensure compatibility with all MIDI devices, Poly 2 offers a wide range of customizable parameters. It also supports MPE, allowing for delicate performance expression, so it functions perfectly with connected MPE devices.

There are many standards for pitch CV and gates, and Poly 2 supports most of them. You can use them with Eurorack modules, Buchla synthesizers, and any other CV-controlled device, past or present.

MPE (MIDI Polyphonic Expression) is a new MIDI specification officially adopted by the MIDI Association in February 2018. It supports polyphonic performances such as pressing and shaking keys while playing, which are common in recent MIDI controllers and synth apps. This allows for even more nuanced performance than previous MIDI implementations.

Four Modes and Completely Different Possibilities
First mode and Next mode are ideal for building your own polyphonic synthesizer.

Channel mode converts data received from MIDI channels 1-16 and sends it to the corresponding voices. This mode is what most users use to connect to a DAW or external sequencer.

Note mode translates incoming MIDI notes C through G and outputs gates from their corresponding voices (regardless of octave). Ideal for triggering drum sounds from drum pads or drum triggers. CV/Gate pairs for up to 8 voices and 12 configurable outputs
Customizable inputs and outputs (pitch standard, pitch bend, middle C, voltage standard, etc.)
Save and load parameter sets (including auto-save of current settings)
Versatile play modes (First, Next, Channel, Note)
Scale filter (select one of 39 scale filters to create musical phrases without music theory knowledge)
