Diy velocity output circuits?

So I don’t know if this is exactly possible or if some circuit is available, but I was wondering if there is some kind of circuit or module that can output independent velocity, after touch and/or modulation. Basically like the synthrotek midi to cv expander as an example. I know that those outputs would be controlled by midi, but is there any arduino projects or circuits that are able to maybe receive a midi signal and just output independent velocity, modulation, and after touch outputs?

I’m a little confused by your question. The LMNC Midimuso module outputs velocity, aftertouch, and modulation. Is that not what you’re looking for? Also my MCVI project outputs velocity and modulation. If I’m misunderstanding what you’re asking I apologize, in that case maybe you can clarify.
