How to use the machine. Each row is a track. Use the amber instrument dropdown in a track's label to swap its sound — there are 23 voices grouped into Drum Kit, Hand & Tuned, a tuned Timpani Set, Bells & Gongs and Vocal Hits. Tap the coloured pad beside the dropdown to play that sound by hand — handy for ringing a triangle or gong over a running loop. Play loops the pattern; Once plays it through a single time then stops. M mutes a track, S solos it, and the gear opens its mixer.
