heya Michael,

As far a I know MIDI protocol hasn't actually changed since the 80's. Your old insstrument will work as well as it can work, IE: if it doen't have aftertouch & you are using it as your controler any sound module you plug it into will not have aftertouch available to it.

The same goes for polyphony, what the module recives will be limited by your controler, if it has 8-voice polyphony the module will only be able to play 8 notes at once.

I've never had any speed, or 'resolution' problems, realtime is realtime I've never had any lag with any of my systems.

MIDI is pretty simple if you use it simply (which seems to be what you want to do).

I use an esoniq VFXsd for my piano controller (put out in 1989 or 90 I believe) and use an EMU Proformance 1 module for my piano sounds. The proformance module is wonderful it has 16 bit stereo samples & I think you can find them used for under 100 bucks nowadays. This'll give you a rundown of the module http://www.sonicstate.com/synth/emu_proformance1.cfm

Good Luck & Take Care,
Rick
