Left hand: touch a chord button along the top to play it — it sustains until you touch another (touch it again to release).
Right hand: touch the pads on the right edge — KICK loops every beat, SNARE every other, BASS pumps house bass with the kick. Touch again to turn off.
Open your mouth to arpeggiate the held chord — wider is faster.
Raise two fists to speed the drums up (×2 → ×4 → ×8 as you lift); open your hands to reset.
Pinch thumb and index together (like an OK sign) to lower the volume — open your hand and it comes right back.
Cover your mouth to stop everything.
Objects mode: pick a sound, hold your finger on any object in view to pin it there, then switch to "Objects — play" and tap the real thing.
