"The Sequential Circuits Tom Digital Drum Machine includes 8 basic drum kit sounds: kick, snare, 2 toms, open / closed hat, clap and crash. The Sequential Circuits Tom had an interesting feature for an early drum machine; each sound could be dynamically allocated between the voices, so you could even use 4 copies of the same sound simultaneously.Other features include the ability to play the sounds backwards, MIDI controllable parameters and support for sound cartridges, which let you add 7 additional samples.
