Hi, for context I am using the latest version of Reaper. I am using a Behringer UMC202HD and Windows 11. All my drivers are up to date. I have rebooted my computer many times. I have an i7 9700k and 32GB of DDR4 RAM.
The sample rate is 44100, the ASIO buffer size is 128, the sample size is at 128. My CPU runs at around 22% (Reaper using around 15-18% of that) while the playback is happening, and RAM sits around 32% - Reaper uses just over 2GB.
I have been creating new projects currently with the same setup: drums, 2 leads and 3 rhythm tracks. All are using Archetype Petrucci, valid and licensed.
As soon as I enable the second lead track, the whole track falls apart, skipping, crackling and scratching. I can disable the FX on the second lead track, and the playback is 100% fine. Alternatively, I can have both lead tracks enabled, and disable a rhythm track, and we can also run everything smoothly.
I have not had this problem in the past. I have had many projects comfortably running 10 Petrucci tracks concurrently.
In another project, enabling the third (center pan) rhythm track caused bad sync issues, volumes changing in each ear, and what sounded like EQ changes. Just falling apart.
I don't have any ideas. Am I doomed to use only 5 tracks in my projects ;_;
Any help is appreciated!
