I'm new to using VEP on a two-computer set up. My new PC has an Intel i7 (12th gen), 64 GB of RAM, and two Samsung SSD drives (one for the system, and one for samples.) My Mac running Logic is from a MacBook Pro 2016 (touchbar), with a 4 core (8 thread) processor and 16 GB RAM. I have them connected through a new D-Link Gigabit switch, and set up a static IP on both machines.
So far, I'm having trouble getting good performance from the new system when I try to have more than 2 audio returns from the PC (i.e., 1 stereo return). If I have 4 or more audio tracks coming back from the PC, the system can't seem to handle a full orchestra set up. I'm mocking up the Superman march for practice. After the tempo picks up in bar 8, as the other sections enter around bar 16-23, the notes start hiccuping and coughing until it totally falls apart.
So far, I've tried: connecting the machines directly, experimenting with different settings for the number of cores in VEP and Kontakt, unplugging the switch and router (to reset it, I guess), disconnecting from the router, increasing the audio buffer to 1024 in the Logic audio prefs, using AU3 instances, using only AU2 instances, using fewer instances, using more instances!
But the only thing that seems to let it work is only using one stereo audio return from VEP. This is a pity, as I'd like to be able to separate out shorts from longs for mixing purposes, and things like that.
(On another forum someone suggested switching to Jumbo frames on my network, but for some reason my Mac and PC both reject setting the MTU higher than 1500.)
(Fyi, right now, with the full orchestra loaded it uses about 32 GB of RAM). I'm using VEP7, Kontakt 5, and the latest version of Logic. If you've read this far, thanks!!
