Midi Poly Grid app for iPhone and iPad

# Midi Poly Grid

This App is Open Source. Access the code here: https://github.com/anzbert/beat_pads


This App is **ONLY** usable as a Midi Controller. It does **NOT** produce any sound on its own and requires a host application or a second device with a DAW or other sound production app.


Midi Poly Grid is a lightweight Midi Controller app for mobile phones and tablets for melodies and finger drumming at home and on the go. Connections can be made virtually to other apps via platform midi channels or via USB to other devices.

This app aims to be an easy-to-use pad input device featuring a variety of layouts, intuitive playability and modern modulation options, such as MPE and Polyphonic Aftertouch. It was designed for people that prefer pads to pianos! The focus of this app is not to be a jack-of-all-trades Midi swiss army knife, but instead to be a great at one thing: Intuitive and versatile pad controls.


Can be used with any Mac via USB or WiFi. Usage with PC is limited to WiFi with free third-party software (rtpMidi), and USB with third-party USB midi connectors, due to Apples limited implementation of USB Midi on iOS.

AUv3 is unfortunately not supported at this time, as it is currently impossible with Flutter. More info about that here: https://github.com/flutter/flutter/issues/16092
