I think we missed the point :) I have used the iGrand from the iPhone on many occasions and it does indeed sound great. My only concern is that it is not in a rack form and so with all of the extra cables and the fact that it is on my phone, it makes for inconvenient usage when playing live.
That is why I posted my initial query about a good piano sound for the VFX. I wish that I had the version with the Mega-Piano waves because that would likely be good enough for live use when layering.
If course, that is all negated now because I don't use the VFX for much live use anymore. I picked up a vanilla VFX, but in attempting the hardwire, broke it :) I still have my VFX-Sd but that was for studio use only.
My best friend's brother is an engineer and is looking at the PCBs for the VFX to see what he can do to fix it. If it cannot be fixed then I think that we may attempt to make that VFX a rack mount unit. I am not losing much sleep over this one not being used because of the VFX-SD as well as all of my SQ racks and my SQ2/32, which all work perfectly.
In fact, my live rig right now consists of a Korg M50, Roland M-SE1, Roland JV-880, Yamahha TX1P and Ensoniq SQ-R. Tha piano on the M50 is sufficient to use live so I do not have to use the iGrand live.
