The CGS59 is a Serge inpired multi-stage sequencer. Unlike most sequencers, this one makes no use of binary counters. Rather, it uses a set of individual stages, each one directly accessible. As such it could be considered to allow "random access".
We currently offer kits for 4-Step, 5-Step and 8-Step Programmer/Sequencer units. Other step configurations available on request.
See the CGS87 for a more generic PCB design
