I tried Cantabile 32-bit for a week or so then recently switched to 64-bit (3.0.3279).
If I just use my internal sound card then things seem fine. When I plug into my Steinberg UR44, Cantabile seems to crash reliably when I close the app.
Is there anything I can do to help you diagnose this?
Thanks - I just checked and in C:\Program Files (x86)\Yamaha\Yamaha Steinberg USB Driver looking at the details for ysusb_asio32.dll/64.dll they’re both version 1.10.0 from Dec 2017, so I think I’m up to date
