Hello All!
After struggling alone for a month or so I have finally (Like a male driver hopelessly lost in an unfamiliar part of the countryside) realised that i need to ask for help! I consider myself fairly clued up with Logic and mac audio in general (heavy user since 4.8) but this issue has really confounded me.
I run Logic pro (9.1.8 but the problem was with me from 9.1.7) on a mid 2011 27" iMac (Processor 3.4 GHz Intel Core i7, Memory 8 GB 1333 MHz DDR3, Graphics AMD Radeon HD 6970M 1024 MB, Software OS X 10.8.2 (12C60), but i also had this problem with 10.7.latest) with all software updates installed. My interfaces are 2xMH 2882's (both 2D one with dsp) and an M-audio profire 2626 running the latest drivers. I have a Lacie D2 (with a 120Gb SSD cludged in there wired through a sonnet TB->express card->FW800) and a drobo 5D via TB.
In almost every project i run i get disk overloads and core audio type overloads (typically when entering a chorus or when more audio tracks start) even with 3/4 audio tracks (48/24) this problem persists, I've tried changing buffer settings, I've tried shifting projects to different drives (including the internal 7200 iMac drive) clean reinstalling and slowly working my way through previously known working versions of OSX and Logic but to no avail. After failing to get the hardware diagnostics running on the iMac i took it into my local apple store (thankfully just around the corner, not as easy to carry about as my MBP!) where they ran a loop diagnostic overnight, with no faults found. I should say this system *used* to work just fine, unfortunately I was extremely busy in the studio when this started occurring and my only recourse was to move back to my 17" MBP (2009) and I honestly can't recall if i did/installed anything when this started occurring. I've exhausted my troubleshooting routines and the patience of my local apple store. The time has come where i need to man up and defer to the esteemed LUG!
I hope i've given you guys all the facts you need, I'd almost be happier to get a crash out and hence a diagnostic report to see where its failing. I've opened up the console to monitor for error messages but don't see any. The cpu and HD meters seem to bumble about at the bottom of the range and then spontaneously peak.
Any help or advice will be much appreciated!
All the best, Mike
