Oddly, the manual from M-Audio does NOT include a midi implementation chart. I recently bought one of these used to have an on-the-road all in one recording interface. Also to use for lead soloing.

I am just trying to find out if I can count on it sending aftertouch.

I've been playing along with a bunch of those bandlab loops with my Casio XW-P1, which has a killer set of built in leads, but the keyboard itself does NOT send aftertouch.

Back in the day, I always used my venerable ESQ-1 or VFX-SD; the latter of which had polyphonic (per note) after touch.

I got used to the channel aftertouch for adding flavor to leads for vibrato, filter cutoff changes, etc, all without twiddling knobs.

As I don't play leads very often, I didn't even know this was a missing feature of the XW-P1. I didn't think to even look for it when I bought it, I was so jazzed it had a tonewheel organ synth engine as one of the synth engines built-in.

So, anyone that MIGHT have an Ozone from back in the day, and maybe original documentation, that could tell whether it transmits aftertouch or not. There is a hint that it might as there is a chapter in the user manual which tells the default controller outs settings and aftertouch is listed as default OFF (I am hoping that doesn't mean that OFF is the only choice!).

M-Audio won't even let you contact them about legacy discontinued products from their on-line form.

The other thing I HAVE done with this little setup is I bought a WIDI bluetooth transmitter from CME, and I have successfully controlled the keyboards in garageband on my iPad using a midi bridge. no noticeable latency. Way cool.
