The MSQ-700 is an 8-track sequencer that holds up to 6,500 notes that can be stored. Functions of the MSQ-700 include a chain function, multi-track function, overdubbing and a merge function. Control your TR-909, or Juno-60 or any other MIDI equipment. The MSQ-700 is compatible with both MIDI and Roland's proprietary DCB sync methods (although it can't do both at the same time). Made in Japan.
