If you need more MIDI functionality, pull the retrofit out and buy
and Encore Electronics JP8 MIDI kit.  It does everything under the
sun, and then some.  Tony is on this list and can give you more details.
Their web address is:

They also make the best OBX, OB8, and moog Source kits on the planet.
Oh, and did I mention their eight channel MIDI to CV?  It kicks butt.

And to answer your first question, yes, it is probably only
note-on/note-off.
A good designer can implement features with little extra hardware (like
Tony)
but it sounds like your MIDI retrofit uses the Z80 only to scan the
existing keyboard, receive/transmit MIDI note-ons/note-offs, and then
control the JP8 through the keyboard buss.
