Patches and discussion for Ensoniq VFX family

Hi, im new to this group. I have an SD-1 and i think it's great but
i'm having a few difficulties: the aftertouch seems not to respond
except when pressed very (very) hard at the middle of the keys (the
extreme for the blak ones), and i want to know uif there's something
to risen up the poliphony of the synth (mine is the "classical"
non-32-voices version).

I hope someone can help me out (at least i want to know if the matter
of aftertouch is normal or not, i'm new to synthesizers).

Also: is there a way to convert the song data of the sd-1 floppies to
standard midi files?. That's it, goodbye. Thanks.
