Hello good folks, I am slowly making progress with GP4 and my Antelope Audio Discrete 4 Synergy Core. I’ve been successfully working with routing and different plugins in GP4 (mostly Plugin Alliance amps and Eventide H9 effects), working on gain staging with my interface, and then dialing in UAD OX as my output (cabs, mics, space, and final FX).
One of the things I was excited about was Antelope’s AFX2DAW plugin which allows their hardware powered FX (think UAD Apollo) to run in a DAW – I have been doing this in Logic successfully for about a year.
Today I tried using AFX2DAW in GP4 but experienced the first perceivable latency issues with any plugin with GP4. I’ve been running all of my GP4 experiments comfortably at 64samples with zero issues and no sense of latency, but with the Antelope AFX2DAW instance I was getting definite latency; essentially unplayable live at 64samples. I dropped down to 16samples and things sounded ok, but that is clearly not the issues – Antelope, I think, is the issue. I tried the AU, VST and VST3 versions of the AFX2DAW plugin.
I’m reaching out to anyone here who either has an Antelope AFX interface (any of the Synergy Core line) or knows about potential issues with AFX2DAW and GP4.
From what I read, the afxdaw plugin is only meant to introduce a very small latency of a few ms.
It’s surprising if you get a different behaviour in Logic. Have you ever tried any other DAWs to compare? I know Reaper will tell you the latency introduced by a single plugin, so could act as another point of comparison.
For a simple workflow like what you’ve got in your screenshots, would there be any difference not using afxdaw at all and routing straight to specific output ports/channel that has your synergy fx?
