I'm using PT2022 B3 and found that when I render MIDI tracks to a WAV file, the CPU overloads and I get instrument drop-outs. I've tried files that previously rendered OK and they also cause an overload. I tried the same files in RealBand 2023 and, again an overload.

I then tried the original offending MIDI file on a laptop with PT2020 and, while the CPU didn't overload, there were instrument drop-outs, even though the MIDI file played correctly on PT.

I haven't exceeded the polyphony limits and I've checked CC64 for errors. My audio drivers are up-to-date and I'm using a Focusrite Scarlett 4i4 3rd gen interface.

Any ideas what is causing the problem? I need to resolve this as I have a number of backing tracks that are waiting to be finalised.

Any advice would be appreciated.
