1) Open Sonar
2) Create new 24/96 project
3) Open Browser, navigate to some REX samples (coming with Sonar)
4) Start "previewing" samples/loops (click on one, click on some other and so one). I guess on fast computer you need to preview 10-20 to notice the effect later
5) Close the project (with out without saving, does not matter)
My observation in the "Transport module" on Control bar: for each previewed sample, I see "Sample rate conversion..." and "Loading REX". If I have browsed many samples, that takes a while.
By itself that does not bother me. But starting with some update, I get regular Sonar crashes after I close Sonar. And now I think that can be related.
