Marble mode. Tap or click = ink drop · drag = comb · two-finger twist = vortex · two-finger pinch = fold · long press = pressure (hold or push up to feed ink, pull back to stir) · pen = stylus wake (pressure sets the tip) · mouse: right-drag = vortex, Shift-drag = fold, Shift + right-drag = pressure, middle-drag = wake. In the Anod medium the same gestures play its operators: tap = strike, pinch = burst, twist = torsion, long press = torsion feed (pull back to stir the cells). A MIDI instrument plays straight in on Chrome/Edge. Settings live in the panel at the top left (the desktop app's settings window, in the browser). Got it
