Is there a CC# for pitch? I want to use my new MP-201 to control pitch via MIDI, rather than CV.
Hmm well could you set up your patch on the LP for maximal pitch wheel play (I think it is +/- 12 semitones). That would give you 3 octaves to play with if you were sending and manipulating the CC# for the LP’s pitch wheel.
There’s a CC for Osc2 Freq, but that’s it.
There’s no CC for Osc1 pitch (or frequency I should say) because it’s the main osc, not adjustable. Osc2 frequency is always an offset from Osc1, with a CC to control this offset
There is, however, a CC (74) to control Osc1’s octave range. Osc2 has one too (75).
As I understand it, things like pitch, velocity, and the gate signal are separate from CCs in MIDI signals. I think they are referred to as ‘events’ and are handled a bit differently.
That’s a fun one to modulate.
You betcha! 
That’s pretty much it (with the exception of gate stuff i have not looked into yet). They are actually part of the foundation of the midi specification and belong to simpler groups (4 or 5 of them) below the CC’s and NRPN’s. Many are simpler because they require less parameters to be passed along, which in turn favors execution speed at the firmware processing level.
The Note (or pitch) event is the most important of course. I would have to fish out technical docs to make sure of the “event” semantic, but it’s a meaningful word to use.
