Roland TR-707 Rhythm Composer, Japan 1985

Roland TR-707 Rhythm Composer to automat perkusyjny wydany przez Roland Corporation w 1985 roku. Roland TR-707 posiada piętnaście cyfrowo próbkowanych dźwięków. Instrument posiada 10-głosową polifonię.

The TR-707 has fifteen digitally sampled sounds. The instrument is capable of 10-voice polyphony. The alternate bass drum, snare and hi-hat sounds cannot be triggered simultaneously. The instruments are labeled as Bass Drum, Snare Drum, Low Tom, Mid Tom, Hi Tom, Rimshot, Cowbell, Hand Clap, Tambourine, Hi-Hat (Closed or Open), Cymbal (Crash or Ride), as well as an additional function labeled accent, which serves to rhythmically modify the volume of the other instruments.

The TR-707 provides four levels of shuffle that operate globally on the rhythm, as well as flam that can be applied to any step. The device offers 64 programmable patterns, which are editable via step-write or tap-write, that can be sequenced together into any of four different tracks. Patterns and tracks can be stored on the device (providing that two AA batteries are inserted) or onto an optional memory cartridge with twice the capacity.

The TR-707 is particularly sought after by users of Roland gear from the same era because it can synchronize with other hardware via both MIDI and DIN sync, although it cannot do so when controlled by other hardware. There is also an output that allows the Rimshot to trigger hardware that accepts a voltage pulse. There are individual volume sliders and output jacks for each instrument group.
