I may be preaching to the choir, but I just found out that RME made a class compliant mode for the UFX giving 22 channel IO for Ipad. Yea!!! Also, there's an RME template to run TotalMix with metering and way more than Mackie Control with TouchOSC wirelessly. Just downloaded and haven't run, but very psyched. With RME, I could use Ipad as effects processor and looper for Axe. Boggles the mind.
