Hey, that would be great :) you can directly email if you can't post,
or, whatever you prefer is fine. I contacted the guy who had the
original presets on his still, and he said he's going to try to get
them back into wav form soon, so I'll probably post a sysex or midi
file of them to the group as well (for space reasons).

As for the rest of the functionality of mine, it's really in tip top
shape. All of the voices are consistent, the tune is dead on, all the
buttons work, and very few show any wear...in fact the entire unit
has hardly any wear on it. I think besides the sliders, the only
other thing I've found wrong with it is part of the panel on the top
of the 'assignable control' section started to bubble up a tiny bit.
I'm not too concerned about the headphone jasck atm either, I just
split off of the high output, and there's no noise I've noticed yet
if the patches are at max volume. Thanks for the tip though, it may
come in handy at some point.

Cheers
Byron
