If you’re getting Logic Pro’s dreaded -10011 system overload error, it simply means your computer doesn’t have enough resources to perform realtime audio processing. Before you go out and buy a new computer, here are a few tips that might just fix the -10011 error.
Increase Your Buffer Size
To increase Logic Pro’s buffer size, go into the application’s preferences menu and find “I/O Buffer Size” under the audio tab. Logic gives you options from 32 samples all the way to 1024 samples. Setting this number to maximum means Logic will hold 1024 samples of audio data in buffer before sending it the CPU for processing. This means the CPU is accessed LESS FREQUENTLY, and there will be less chance of a -10011 system overload error.
The downside is that latency will be increased, so a setting of 128 samples is the recommended maximum for live recording. If you’re mixing with a lot of plugins, increasing the buffer size to 1024 is perfectly fine (and recommended) because all of the audio has already been recorded.
Use Stock Plugins While Recording
If you record with a high buffer size, the resulting audio will likely be off with the rest of the mix. To avoid getting a system overload error during recording, you should use stock plugins. It’s perfectly fine to use the built in EQs and compressors when recording, especially if you don’t have a super powerful computer. These stock plugins are usually built for efficiency, and use very little resources.
Use Effects Sends
Certain effects like reverbs and delays can be applied on a global level via auxiliary sends. The better way of doing it is to route whatever you need to ONE aux track with ONE reverb plugin.
Bounce to Audio
If you’re done recording your parts with resource-hungry virtual instruments, there’s no reason to keep them enabled. Bounce them to audio, and disable the VST plugin. This will ensure you’re not wasting any CPU or RAM on something you don’t need.
RAM and Hard Drive
RAM is a much faster kind of memory, and having enough of it is crucial for music production software. When RAM is running low, OS X will automatically start caching data to your hard drive or SSD. Depending on how quick your drive is, your computer might slow down to a crawl.
The recommended minimum amount of RAM for modern sample libraries and software is 8 GB. Anything less than that is risky, especially considering it’s common for OS X to use 2 GB or more for system processes. Maximizing RAM will help cut down on -10011 errors in Logic Pro.
