ok so i am using live 5.2 on a 700mhz ibook with about 360 mb or so of ram. i am also using two m-audio usb midi controllers. sometimes while playing live with both controllers live, the software, will freeze up. i'm pretty sure this has something to do with the fact that i am using both usb ports simultaneously. anyway, my question is: has anyone experienced this same problem before? and if so, what, if anything, can i do about it? thanks.

I am using a similar set up....

I have 2 m-audio controllers linked to my Mac G4 and I used to get a freezing all the time.

The problem turned out to be a rogue VST I was using and nothing to do with the actual usb or Live.

Once I had removed this VST from my system and deleted everything to do with it my problem was fixed.
