Drum Machine
A drum machine — drop it and a beat loops through the General MIDI drum KIT; a Clock drives playback. THE CONDUCTOR MODEL: the kit is fed into the Step Sequencer's Material, so each drum piece (Kick / Snare / Hat / toms / cymbals) becomes a lane. Open the sequencer to paint the grid — click / drag-paint cells, set Rate / Gate / step-count. Load your own multisample (or swap the kit) and the lanes follow whatever you feed it. A FUNCTIONAL preset (explicit nodes + connections); the Instrument auto-loads the GM drum kit on drop.
