Hi Pierre

Do you have any news on this topic?

Today I had some time to reproduce the problem again.

To get a clue whats going on during the crash or hang I used the Sysinternals Process Monitor from Microsoft.

Reproduction steps:

1. Download and unpack Sysinternals Process Monitor.
2. Start Process Monitor.
3. Press Ctrl-E to stop event capturing.
4. Press Ctrl-X to clear the display.
5. Start TS2.
6. Load Gong_Test_Preset_18-22_Mix.wav I send to you.
7. To capture events generated by TS.exe. In Process Monitor, use the crosshairs (red circles) and drag it or select the TS2 window with it.
8. Press Ctrl-E to start capture events.
9 Press Ctrl-A to set auto scrolling to on.

At this point you should see that TS.exe is producing six events every second (CreateFile, QueryBasicInformationFile, CloseFile..., CreateFile, QueryBasicInformationFile, CloseFile...). Even if the sound is not played or TS2 is not used at all. That looks a bit strange. Like an infinite loop or a thread that runs continuously and never finishes. When you double click on a specific event, you can view the event properties like process tree, loaded modules, and the stack.

10. Switch to the TS2 window and split Gong_Test_Preset_18-22_Mix.wav into 5 regions.
11. Set the crossfade length for each region to one third of the region.
12. Move the regions and start cross fading.

At this point, TS2 begins to lag or hang. CPU usage stays at around 50%. When it hangs, TS.exe generates millions of ReadFile events every few milliseconds in the process monitor.

If you have any question or an advice please let me know.

Hope this helps.
