Patches and discussion for Ensoniq VFX family

I see. Some comments on the aftertouch problem?

And, If the Sd1 has 21 voices, then, is the synth going to transmit /
receive only that amount of voices via MIDI? (i. e. if i made a song
and run out of polyfony, can i send the tracks to other midi
instruments, even though the tracks already surpased the maz amount of
notes at the same time of my synth?)

Thanks, these are basic questions but i don't know much about synths.
Goodbay, i appreciate your help.
