A rather technical question but I was wondering if someone has an answer to this:
I'm using a Mid 2010 Mac Mini (2,66Ghz Core 2 Duo, extended 8BG of RAM) running the latest Logic Pro X on OSX 10.11 for recording which usually is working very nicely, meaning
16-track simultaneuous audio recording or up to 10 tracks of software instruments usually works pretty smoothly.
But I have recently started using more tools using NI's Kontakt and Reaktor Plugins which seem to be a little heavy on the system.
As soon as I hit 3 or 4 tracks with the mentioned plugins it will not play back even a second of the mix before overloading and telling me it could not calculate everything in time.
I have even tried out setting the I/O Buffer from 128 up to a staggering 1024 but it had no effect on the result.
Now my question is: Does someone know what the bottleneck is here? CPU or RAM?
If it's RAM I could bump it up to 16GB if the system supports it, if it's the processor I'll have to think about upgrading.
