Patches and discussion for Ensoniq VFX family

Hi, I'm a recent member to your group (as in, today...).  I acquired a 
VFX synth (not an SD, unfortunately) from a relative, and I'm really 
enjoying it.  I ordered a manual online, and am still waiting for it 
to arrive.  However, I am desperately seeking help on a particular 
issue, namely, that I plugged in my YAMAHA sustain pedal (basic 1/4" 
single ring plug, works on my other keyboards) to the pedal input on 
the back of the module, and the polarity appears to be reversed.  So, 
when I depress the pedal, it causes the sustain to turn OFF.  I've 
searched through every option on the MASTER screen, and I can't for 
the life of me find a way to reverse the polarity.  My only discovery 
seems to be that it's meant to use a dual-pedal unit.  Can anyone help 
me out with this terrible problem?  I'm aching to start using it and 
this single problem is standing in the way of my total and complete 
enjoyment.  Thanks!
