SEQUENTIAL CIRCUITS DRUMTRAKS

DRUMTRAKS lets you program volume and tuning individually for each of its 13 real drum and cymbal sounds. This allows you to "expand" your "drum set" to include the sounds of gongs, 32-tom rolls, gorilla claps and more! Extensive editing options include auto-correct, overdub, record, erase, and copy modes. Drumtraks features a programmable mixer with a monophonic output (which can drive stereo headphones).

For control by external mixers or processors, six audio channels (plus the metronome) are available at the back panel through standard 1/4-inch phone j acks. The Drumtraks overall memory capacity of over 3300 notes can be allocated to up to 100 different drum patterns, any of which can be up to 100 measures long in any time signature. Tempo range is 40 - 250 beats-per-minute. Each overdub of a pattern can be recorded with a different instrument volume or tuning, in real time, or auto corrected to one of eight levels of resolution. Any part of an instrumental track can be erased. Patterns can be copied and added together (appended). Once drum patterns (sequences) are recorded in the Drumtraks memory, up to 100 songs can be defined.

Basically, songs are made by chaining patterns together. Each song can consist of up to 100 steps. Steps specify how the song is built by selecting patterns and inserting volume or tempo changes. Songs, too, can be edited, copied and appended. The Drumtraks' memory is retained even when power is off thanks to a backup battery with a ten-year life. For permanent storage and reprogramming, the built-in interface can be used to store the contents of memory on a common cassette.

The Drumtraks features two built-in interface systems. There is a selectable 24, 48 or 96 pulse-per-quarter note clock input, and a 24-pulse clock output for older sequencers or rhythm units and sync-to-tape. For operation with computer-controlled sequencers, the new MIDI interface is also provided. This enables the Drumtraks to synchronize to SCI's new Model 610 Six-Trak multi-timbral synthesizer/sequencer, or any other MIDI equipped instrument. For example, the Drumtraks can be played with full velocity control from the keyboard of the Prophet-T8, allowing for easy, real-time recording of drum dynamics!
