Scott,
Please excuse my belated response, concerning my Tyros settings with the PAS. These days I do not practice at all and I do not usually have my Tyros with me (only bring it to gigs on weekends), and additionally I have been travelling and really busy.

Ok, to the business :-)
Here are the promised settings I use with my Tyros and PAS:
Very important: try the PAS preset #57!
Then, in the Tyros:
Equalizer:
Q:2,5
Freq: 225 Hz
4/3/2/6/8
Compressor: Punch preset
You can also try Gary's settings, they should work as well. Then set the PAS equalizer according to your tastes. The real important thing is that you choose an adequate PAS preset. I doubt you will be deceived with the results... You may not be very happy with the price, but that's another story :-) Good luck, and tell us about your experiences!
