Ray Wilson of Music From Outer Space has introduced a new synth DIY project, the 16 Step Sequencer Vari-Clock Quantizer, designed to be integrated with the MFOS sequencer.


  • Each step’s duration can be set independently.
  • Each step’s duration is settable from 1 to 16 clock cycles.
  • Main clock adjustment affects all steps equally.
  • Clock selection: Quantized or Normal
  • Two gate/trigger modes: Single per step and Multi per step.
  • External clock supported.
  • Clock out supported.

Here’s an in-depth intro video for the 16 Step Sequencer Vari-Clock Quantizer:
