I have been wondering what to do with my five beloved Shruthis. I haven’t wanted to sell them, but also haven’t used them much since getting into eurorack. But now there is this: https://github.com/mxmxmx/CV2Midi (which re-uses the Braids quantiser code via the Ornament & Crime code base). Quantised CV, trigger/gate and velocity CV in, on five independent channels, and MIDI out. DIY only at this stage, I imagine, contact Max (mxmxmx) for details.
I don’t think the firmware for it does SysEx messages yet, but I can’t see why that wouldn’t be possible, so CV control over patch banks etc should also be possible.
Of course, CV2MIDI is not a new thing, but this one is affordable, has pretty good precision, and is open-source and thus extensible.
