Drums
The DRUMS block (moderate-mode Rack) — a self-clocked synth drum machine as ONE card: a Step Sequencer paints a synthesised kit (kick / snare / hat) over its own Clock, out to the Speaker. The step GRID is the block's face; the macros (Tune / Decay / Snap) shape the whole kit. Drop it and it plays; paint the grid, turn the macros. Open it to reach the sequencer + drum synth.
