I wanted accurate practice diagrams for Ableton Note, but static charts became crowded and often obscured the actual grid geometry. I built a free interactive reference that generates the iPad, iPhone and Push layouts algorithmically.
It supports multiple simultaneous scales, modes, chords, arpeggios and exact voicings. You can also tap pads to identify chords, alternative interpretations and inversions.
The app runs entirely in the browser, requires no account, performs no tracking and is open source.

Corrections to device geometry, theory data and chord naming are welcome.
