Information

Midi Poly Grid (formerly known as 'Beat Pads') 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 great at one thing: Intuitive and versatile pad controls.

AUv3 is unfortunately not supported at this time, as it is currently impossible with Flutter.

Wifi works on iOS, but Wifi and Bluetooth support is otherwise limited due to platform restrictions.

Feature Bullet Points

• A size-adjustable grid of pads for finger drumming and melody input

• Highligh a large number of musical scales
• Receives Midi Notes, making the pads usable like a Launchpad
• Custom grid creation based on the note intervals on the X and Y Axis to create Grids inspired by the Harmonic Table, Wicki Hayden, MidiMech and others

• And more...

Feedback and Contributions

• Anyone is most welcome to contribute, report an issue or start a discussion in the Github repository. Thanks!

ToDo List

• Potential issue: iOS devices disconnect from Midi sometimes when screen times out and wakelock is off -> Implement auto-reconnect to last connected devices
• Low Priority: Project still using outdated ChangeNotifier in Riverpod state management -> Refactor
• Kind of a problem: Too much spaghetti code 😝, in a beautiful pasta bowl 🍝 of a repository!
