I am using MainStage 2 as my in-ear monitor mixer and for vocal and guitar fx and for keyboard patches. I use this mixer for live shows.

I plug all vocal mics, guitar mics, bass into my PreSonus FP10, I use the FP10 as my digital interface to the mac.

I run my keyboard controller and home made USB foot swith through the USB 2.0 ports.

The problem I have is at anytime during a live set digital distortion will creep in while we are playing or even between songs and we have to kill MainStage and re-start it. Sometimes we can go an entire show and not have the problem other times it can happen two or three times within a single set.


I have done the obvious, opening the buffer size in MainStage but that does not help.

I have moved the MainStage concert that we use to an external USB 2.0 (7200 rpm) drive but that does not help either.


I am running out of ideas on how to correct it and wanted to see if anyone else was having this or a similar issue.


I am running a macbook pro 2.2Ghz Intel i7 with 8G of memory running Lion 10.7.5
