I've been working with Mainstage 2 for the last 2 months, preparing my patches and concert with no major crashes. But before we hit the real stage--do you have any additional advice about using Mainstage in live performance? So far my crashes have happened while working on patches, but not necessarily while actually playing. I have some audio playback programmed in (small samples), but the bulk are the patches (about 50 right now) that I've put into the concert. I EQ'd here and there and added a few effects. I already know that I should have all other programs closed, and to turn off any wireless connection.
In addition, I notice that my CPU increases as I work --(per Activity monitor, not MS meter or iStat--why do these all register different percentages anyway?) it goes between 70% and sometimes surges over 100%, with MS memory usage at 32%. I have a Macbook Pro 5.5, version 10.6.8, Intel Core Duo, 4 GB memory.
Any feedback is well appreciated.
