Firmware v2.0.0-dev-12.9 (from GitHub)

I downloaded and installed it from GitHub and it locks up when playing patches that use over 80% of CPU. I removed it and reinstalled 12.8 and all is well again.

Hmm, can you share the patch file? Also on github there is dev-12.10-rc1 (which adds some knob catchup changes) and dev-12.10-rc2 (which does change the audio engine a little bit with some small optimizations). Try those if you want.

Files are attached.
Test File 031525.vcv (3.0 KB)
Test File 031525.yml (14.8 KB)

Running the test file (above) on dev-12.10-rc2 and no hangs so far.
