Patches and discussion for Ensoniq VFX family

Arranging sounds in a VFX so that they match GM wouldn't be very hard, except for the drums. Does 
anyone know a convenient way to do that? Is it even possible to create a drum patch, where at least the 
most common drums would be in their GM equivalent numbers? I've also thought of some kind of 
converting software, which would change back and forth from GM midi file to VFX midi file on a 
computer.

I use mainly my VFX-SD with my Micrologic Fun sequencer program and need occasionally to mix with 
GM midi.
