Not a bad start at all, but a few things to consider:
- Do you plan on growing the rack / what case is this you're using?
- How do you use this rack with external gear? I see you have a pedal interface, is this rack more of an effects unit, or is it more of a standalone instrument?
- Any particular musical goals with this instrument?
- I love that you've discovered the compare 2 and sequential switch. Those specific utility modules, along with vpme.de's T-43, doepfer's matrix mixer, and the Ornaments & Crime, made a world of difference to my own workflow and understanding of how to build an instrument and manipulate voltages (and therefore, sound).
