Really stuck on a slow midi problem. I can no longer play midi into LPX via my PreSonus Quantum 2 and expect it to keep up. Notes are dropped, play at random intervals after I press a key. Just unusable.
This is on a 12-Core 64Gb MacPro, I've been through all the possible steps to optimise the computer; I have deleted and re-installed the PreSonus drivers, and I have epxerimented with every buffer size from 32 samples to 512 samples, with and without low latency mode. No difference is made by any of this. Used to work just fine, and my my Alesis QX49 - connected via USB - works just fine.
I can only conclude that there's something between Monterey 12.2 and Logic and Presonus that is no longer playing nice.
I would be extremely grateful for any other things to try - I'm on a deadline for a project and I need my 88 key keyboard for it!
