Push 2: optional

Got a Push? Play it with your hands.

Tuple works fully with your mouse, a MIDI keyboard or any controller , no Push required. But if you own a Push 2, the grid becomes a hands-on surface: grab the pads, and the colors mirror the screen.

One chord per pad. Columns are degrees I–VII + Borrowed, rows are chord families, Push extends the grid, it doesn’t replace it.
Color-coded by degree, synced with the on-screen Layout. The pad you hit lights up brighter while held.
The progression on the pads, PROG mode puts your cards on the bottom row, and substitutes, next chords or voicings above.
