TOM is one of the legendary instruments made by SCI, the capabilities of which seemed ahead of time, and surely raised the bar for other manufacturers. The "humanization" function was incorporated into this device much earlier than the term "humanization" appeared in the world of MIDI.

A wide range of sound conversion capabilities make it possible to get out of eight basic samples much more diverse sounds. For each sound, you can individually adjust the pitch, the position in the stereo panning. Sample can be played backwards, and basic sounds can be supplemented by new ones when using a special cartridge.

The flexible sequencer system allows you to work in two modes: real-time programming or step mode. There are 99 cells for rhythm patterns, each of which can have a length of one to 99 measures. The total number of available programming notes is 2300 with the possibility of expanding up to 5000 or even 10000. Programmed patterns can be combined into pattern sequences (songs) which can be edited.

The "Improv Factor" function allows you to add nuances to the basic rhythm, for example, shifts, which are added to the pattern automatically. "Human Factor" changes the volume and pitch of some beats, which adds life to the sound.

The instrument also provides full MIDI support in real time (note, volume, velocity).
SCI DrumTraks has a model number 400, TOM - 420, and Studio 440, which is essentially a combination of two TOM units (the number of voices is doubled, expansion card slots and TP) - 440.

The sound of Sequential Circuits TOM can be heard in the works of Juan Atkins, Janet Jakson and Prince.
