So I drew out my idea for the CV sequencer I want to build in MSpaint, bottom left would be on/off, middle would be a/b and right would be b/c.
I'm sure there are a few flaws in my crude drawing, but I think you get the point of what I want to do.
I think I want each sequencer to be 6 steps with toggle switches under each one to bypass it. As well as the ability to switch between auto and step Zvex style (as seen in the drawing, although this is not mandatory, as long as I can do step I'm happy)
What I really want is http://http://www.doepfer.de/maq_hr.htm
but I think that is a bit of overkill for something so simple as a ring mod.
