Accessory for 568 trigger sequencer
The QSTS ASSISTANT MODULE expands the basic M 568 by more inputs and outputs. The four left jacks are reset inputs to have the four sequencer rows of the 568 be reset independently from external sources. The central eight jacks provide trigger outputs, which can be assigned to selectable positions - two on each row of the 568. The rotary switches on the right side of the module allow to change the running direction of the four rows independently: forward, backwards, ping-pong and random order.
These merchants probably sell this module. Huh?
