Mix-Sequencer
An authentic reproduction of the original “System 2500” circuitry from the ‘70s that can fit in a standard Eurorack case. The MIX-SEQUENCER MODULE 1050 allows you to rapidly select waveforms and signals via a conventional mixer format. Controlling and altering a sequence on the fly has never been so easy!
These merchants probably sell this module. Huh?
