Here's how to reproduce the issue:
1) Create a new DP project. Set DP’s hardware buffer to anything *other* than 2048. In my case I used 256. Sample rate doesn’t seem to matter. I *usually* use 48k these days.
2) Create a mono audio track (TRACK 1) and add a UAD-2 plug in to the first insert. I added a mono-to-stereo instance of the Lexicon 480L. Close the Plug-in window.
3) Create a second mono audio track (TRACK 2) and add a mono instance Console 1 plug in to the first insert… it should instantiate with their default SSL 4000 E channel strip. Close the Plug-in window. Using the Console 1 hardware, active the Console 1 On Screen Display, select TRACK 2, then Press Shift + 4 and load a UAD-2 compressor into the Console 1… I used a LA-2A Legacy.
4) You should get this error message that says requested buffer did not match other plug ins:

This seems to also be affected by whether DP’s plug-in windows are open or closed, because DP may switch a plug-in between “real time” and “pre gen” mode depending on the opened/closed status of the window. Pregen and realtime can use different sized buffers in the same project, so under certain conditions this creates a buffer size mismatch between UAD-2 plug-ins. The buffer size needs to be the same for all UAD-plug ins in a project.
Also, this problem ONLY manifests when there’s a one or more UAD-2 plug ins DIRECTLY in an DP insert… AND one or more UAD-2 plug ins inside Console 1. If the UAD-2 plugs are all directly in DP inserts… or all directly inside a Console 1 instance, no problem. It’s the mix and match situation that causes a problem.
