The big take away from the setup is the mixer, and that I'm finally using it for all it can be. I know it's a simple thing, but having my gear routed properly... and actually understanding what's going on is so useful.
I was using the Micro Modular again, but the ability on the Nord Modular to quickly assign a knob to a parameter, as well as multiple slots (with one dedicated to FX processing) brought it back to the table. As a programming tool, the keyboard version wins.
The PO-32 is battery powered funkiness and sample fodder when I want it. The Volca FM has its limits (no program change) but what it can do, it does well. I like the thought that went into it. The SP-303 is for stereo sampling, and arranging the final mix.
I haven't cracked open the Digitakt manual since I've got it. I'm trying to see how far I can go by just following my instincts. So far, so good. The basic-ness of the device is a strength in this regard and has been a source of some amusement. I remember the silver age. Those were powerful machines, but the Digitakt comes easier to me. It just does what it does, and lets me concentrate on the music.
