EWI setup interfering with Mainstage

[liveintokyo]

I have been using mainstage for the last few months live onstage and havn't had any major problems. I recently bought an EWI to use as well and have been using one midi keyboard and the EWI on stage.

 

Ever since I setup the EWI it has come up with an Audio Unit Authorization Error which causes the auvatool to quit unexpectedly. However I have still been able to use the EWI and the Keyboard no problems, for a few gigs.

 

However for my last couple of gigs the sound has started dropping out. First the sound starts getting softer and softer, and then it finally disappears altogether. This can only be helped by rebooting the system - although the same problem occurs quicker. It has happened on my last two gigs and on two different computers (one my macbook pro and then on my macbook mini).

 

Any help would be greatly appreciated - I am at the stage where I am thinking of going back to regular keyboards just to help the problem - can't afford to have keys dropping out halfway through the set.

Or if anybody could direct me to a site where they may have some info about this it would be much appreciated.

Well I finally wiped my computer and reinstalled everything. I didn't put the Garriton software that came with the EWI back on. The EWI and keyboards are working much better now (and not causing everything to crash). Maybe there was an issue with the software? All is good anyway - got my rig back.

 

Only downside is that the EWI seems to be on very basic settings (no vibrato, no pitch bending etc) but luckily that will be fine for what I need it for (just playing horn lines here and there).
