Drum practice that listens back.

drumpy is a practice app for electronic drum kits. Plug in over MIDI, play the pattern on screen, and it scores every bar against the click, then picks what you should work on next time.

Three cards in drum notation — a kick figure, a groove into a fill and a chet groove — each played back with a playhead. Most hits land in time, a few early or late, one note per card is missed, and each card scores a pass. — Every hit lights its note: green is in time, blue a little loose, amber well off, and the dark edge says early or late. A red ring is a note that never came.

What it does

Scores every bar: Each hit is matched to the note it was meant to be and graded on timing. A good bar raises the tempo, a shaky one holds it, and a bad one drops it.
Remembers what you struggle with: Every pattern is a spaced-repetition card with its own tempo. The ones you fumble come back sooner; the ones you own wait their turn.
Shows real notation: Kick figures, fills and 160 hi-hat and ride grooves, written as drum notation with a playhead that follows the click.
Plays along with songs: Loop a section of a track, slow it down, and keep notes at the spots that trip you up.
Replays what you actually played: Each attempt is saved as MIDI, hi-hat pedal included, so you can hear your take against what was written.

The beta

drumpy is in daily use by one drummer and opens to a small beta soon. For the beta you'll need a Mac, Chrome, and a Roland electronic kit connected over USB MIDI. Other kits come later.
