I'm also going to be including a few VCF (Voltage Controlled Filter) modules too, the whole audio signal-path is going to be 100% analog, but there will be some digital circuitry included, like for example a DSP FX module, and a Midi to CV (Control Voltage) converter, I'm also going to be including a small oscilloscope display module, for looking at signals.
Your setup sounds a lot more sophisticated than mine. My only diagnostic tool is a DMM from Jaycar. I have built 4 pedals so far this year, but I am really only just getting into this hobby, trying to relearn some of what I knew when studying electrical engineering (before dropping out) 30+ years ago.

An oscilloscope and an adjustable oscillator for driving the input would be invaluable for testing, tweaking and debugging audio circuits though. I am quite green with envy!
