Sequencer
Choose a platform to open the sequencer editor. Each drives that machine's native sound channels in a tracker-style grid: a strip of block slots on top, a grid of beats by channels in the middle, and a piano keyboard below. The channel layout comes from the platform's Sequencer descriptor. See the Sprites.Media.Sequencer reference for the parts, and the storage format for the saved shape.
