I've been fixing my comp quite a bit recently to try and get the pro-tools errors down to a minimum. And i was noticing I was getting error-9073 very often at the end of songs. I figured maybe this had something to do with regions nearing their end and the comp freaking out for no reason. Turns out the error is only coming up when recording feedback. If we let a guitar go for a bit as soon as it gets to a certain pitch while feeding back, the error comes up and stops recording. We did it a whole bunch of times and confirmed it. If i chance the buffer size it will go away eventually. But I thought that was pretty damn messed up. As soon as the gits are done im off to nuendo! Anyways, The battle continues.... cheers.
