The last note/low note/high note priority settings don't seem to do 
anything on my evolver (#238).

When playing notes from a MIDI keyboard, if I hold a note down and 
try to play another note while holding the original note down, it 
won't play the new note, if that makes sense.  It seems that the 
once a note is played, the only time I can play a new note is if i 
first take my finger completely off the original.  I have the 
setting on Last note priority re-triggering the envelopes but it 
doesnt seem to be doing anything.  Are there any 
suggestions/settings on how to fix this, or is this simply the way 
the evolver is?

Thanks
