Thanks for your kind words Garfield. Yeah, I guess I'm describing it as controller because it doesn't actually generate sounds, well not in this current incarnation. I figured CC was a better route to go down as it would be more a more versatile device connecting to modular systems and other synths. For example, I'm currently feeding the CC from the wheels into a Polyend Tracker to make generative sequences, but also using the the same CC to shape and morph the sounds of the synths the Tracker is sequencing. It just seemed like a more powerful way of doing it, given how well designed almost all music gear is this modern golden age. It also meant the entire device could run pretty comfortable on a single Arduino. I've been using the Polyend Poly 2 to convert CC to CV for the modular system. The 'record' and 'play' wheel work really well at reading and then blending all the CCs. I always wished the crossfader on the Octatrack could be assigned to control multiple CCs but for some reason it can't, so that's why I added that functionality.
I made it from scratch and I'll be posting a 'making of' video in the next couple of weeks. I've also started uploading videos of the musical results here:

I'd be open to commissions down the line but would like to concentrate on making an album with it for now.
Thanks again for your interest...and for remembering the turntable sequencer!
