uToll2 crashes

Hi,

Thank you for your feedback.
Please download the demo material from here: https://cymaticaudio.com/demo/
Copy the related content to your USB drive, use the import function in uTool to import the content to your computer.
Once done, please export the content to your USB drive.
Maybe some content on your computer causes this crash, maybe the track or song name or the midi file etc.
If you have no crash with the demo content we can step further.
