The SQ-80 keyboard is wretched. I have tried to use the aftertouch on it after getting 
hooked on the effect on the 80, only to find it miserable and painful to play.

My understanding is that many manufacturers don't bother to implement poly aftertouch 
because frankly MIDI doesn't have the bandwidth to support the amount of data that it 
generates. The fact that all the aftertouch effects in the 80 are under voltage control is the 
critical difference. Squeezing all that data into 1 midi cable makes the timing sloppy and 
the aftertouch controllers less than smooth. Mostly you hear parameters jumping around, 
rather than gliding around.
