I wanted to up the anti re sample rates and projects from 24bit / 44.1 khz to 24bit / 96 khz.
Keen on the latency benefits also and processor hit (around 40 tracks audio, 10 tracks virtual instruments (not pussys) enough decent plug ins for Bob Clearmountain)
Tired of some of the bad info online. This is for people who know about this stuff (it goes in and out and takes a certain amount of time to get round) with a few observations thrown in for good measure, and a few questions.
Ended up doing a bit of testing re buffer and processor capacity size and what my MBP could take (not interested in monster track counts) and using a ball park mix of audio, non Logic Plugs and Virtual Instruments)
Went to 96khz, buffer 256 (8.8ms delay) buffer 128 (6.1ms delay) buffer 64 (4.8ms delay) buffer 32 (4.1ms delay)
At no point did the system (M3Max) get to 50%. That was on the main CPU gauge in the Control Bar and subsequently the Performance Meter when I figured out how to open it.
I reset Logic before the test so no clever moves re processor were going on (I did enable Complete Features)
To the untrained Coal Mine Eye the latency difference is nothing (roughly 4ms - 9ms) it's a no brainer tbf.
After all this I realized that the MBP was recording all the audio and running on its internal drive (two of the VI,s were running off an external fast drive)
Have I totally underestimated the power of my MBP or got this all wrong.
