M-185 Sequencer

Multi-stage dual-channel MIDI & CV sequencer, with stage selectable gate modes

M-185 is the original multi-step-per-stage sequential CV controller/sequencer. Now available in Eurorack.

Retaining all the original core functionality, it has now been upgraded with a whole load of exciting new features:
8 gate modes with individual clock subdivisions per stage, A/B split mode for two separate sequences, 2 channels of CV/GATE, MIDI IN/OUT, quantise scales OR microtonal.

The M185 sequencer is an original RYK Modular design, first sold in 2009 as a limited edition module, in the Roland 100m modular format. It has since gone on to inspire several other designs including the popular Intellijel Metropolis.
The module comes complete with all the cables needed to get started: 2 x TRS MIDI adapters, 1 x TRS CH2 CV/GATE cable, 1 x Euro Power Cable.
