A collection of hackable web-based MIDI instruments, implemented as a web-based MIDI controller.

I wanted to create a MIDI instrument that allows me to jam with other musicians. Play MIDI with your PC keyboard, or with a touch screen on an iPad.


WebMIDICon works on desktop, tablet, and mobile devices. It lets you use one tool for many use cases.

Connection options

On tablets and mobile devices, you can play MIDI notes and drum notes with your finger. You can put your device on the floor and use its touch screen as a sustain pedal.
