The SMT adaptation was a hobby project. The MFOS designs are the property of SynthCube.

This is my next MFOS Eurorack-conversion project, the Analog 10 Step Sequencer!

You can find all the original documentation on Ray’s website.

As with my previous adaptations of Ray’s Synth modules to the Eurorack format, I try to stick as much as I can to the original circuit, keep component references, etc. So you can cross reference the documentations.
