Pro Tools crashes (Mac OS type 2 or 3 error) while a session is playing back and attempting to process a region with an AudioSuite plug-in (Gain, Normalize).
There are a few things that could cause this including: RAM allocations, hard disk drivers, and drive problems.We’ve seen a similar problem recently where AudioSuite functions applied to file(s) that are shorter than 39 ms or so will cause a crash. You should take note to see if the audio you are trying to process contains any files or fades that short. If so, please call into Tech support, please make note of the drive you’re recording to and what drivers it has on it.There are some other things that can cause this to happen, most commonly, hard disk drivers. This especially could be the case if you’re using FireWire drives and the drivers that came with it. If FireWire drives are being used make sure you use the Apple disk drivers as opposed to anything else. Not only could they cause crashes on AudioSuite functions but also on playback/record and disk mounting. Do a search for FireWire drivers for more info on how to initialize your FireWire drive with Apple drivers.RAM allocations may affect this… Be sure to allocate more RAM to the preferred memory settings of DAE and Pro Tools and NOT the “minimum”. Leave the minimum at it’s default setting! In most cases 80 to 90 MB allocated to each is enough but if you are running large sessions you may need to bump it even higher. I rarely have seen a situation that needs to go higher than 150MB each. If you’re going to increase the RAM be sure you have enough RAM in the system left over for the Mac OS (if you don’t this could cause crashes too).General drive problems may cause these symptoms as well, such as: missing or bad SCSI termination, cabling problems, drives that need to be initialized, etc.Also make sure you’re “disk cache” setting in the memory control panel is set to 512k. If it is set to another value set it to 512k and reboot the computer.Also make sure the latest version of the normalize, gain, duplicate, etc. plug-ins are installed in your system. Check the Pro Tools installer for the latest versions of each for the version of Pro Tools you are using.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
