Per
Yusynth:
This Moon Modular 563 module is apparently the commercial version of a module that was custom-made for Gert Jalass. For Xmas 2006, Gert Jalass sent me a Xmas card showing his sequencer unit including two prototypes of the module that were labelled 963. This is a four voices 8 steps trigger sequencers.

Each switch has three states: Trigger on, OFF, reset.
The pulse width of the triggers can be adjusted independantly for each row.
The module has a clock of its own, but each row can be independantly driven by an external clock."
