Drums

The DRUMS button in the top bar opens two drum machines stacked in one drawer: a practice kit that plays in your browser, and a remote for the GP-200's own drums.

Practice drum machine (browser audio)

A step-sequenced kit that runs entirely in the browser , no GP-200 needed, so it works offline and while you're editing on the train. Pick a kit and a groove, set BPM, swing and volume, and click individual steps on the grid to make it yours. Each click steps a pad through hit, accent and ghost before clearing it again, so the softer notes the preset grooves use are yours to place too; mute a lane to drop the hats or the kick.

Time signatures: 4/4, 3/4, 2/4 and 6/8 , the grid, the bar length and the backbeat move with the signature.
Swing: MPC-style, from straight to heavily shuffled.
RANDOM: rolls a new pattern in the chosen style that still fits the signature , a fast way out of writer's block.
It keeps playing when you close the drawer, so you can dial in a tone over the beat; the DRUMS button glows while it runs.

GP-200 hardware drums (MIDI remote)

Below it, the same drawer remote-controls the pedal's built-in drum machine over MIDI: start/stop, rhythm selection and drum volume, plus the TUNER and a tap-tempo. These need a connected GP-200, and the MIDI channel must match the unit's global channel (default 1) , there's a selector right there if you've changed it.
