I would suspect that if it's a PDC issue, then it's being caused by certain plugins which are not reporting their delay correctly.billcarroll wrote: ↑Mon Mar 06, 2023 9:36 pm A quick Google search for “studio one PDC issues” turns up quite a few hits for v5 and v6.
I did a search for “studio one PDC issues” and the top hit was from the same guy from this thread, posting the same thing on Gearspace. There seems to be a smattering of these reports going back to V3 and V4, too. So it's pretty inconclusive that it is a new or real problem that was introduced in Studio One 5. Again, I think this sounds like a problem with the plugins in question, possibly not reporting their delay correctly.
You can see what latency your plugins report to Studio One by opening the Performance meter, and clicking ☑ Show Devices.
