Hi John, I have to admit that I haven't read all the replies on this matter, but yes the mod wheel acts as a volume level, and if you're planning on using GPO on live gigs this could pose a challenge, however I have found out that if you only want to use the GPO sounds to record a song if you set your volume levels of whatever instrument (strings or wind instruments)to 100%, even though the mod wheel in the GPO edit window does not show as to be affected at all by this, the recorded results are fine. The problem is you cannot "monitor" the recording because you cannot hear it. I have try it before without any problems as far as that is concern.
I hope this help.
