Hi,

I receive quite often these kind of crashes in DryWetMidi from my clients' computers:

Unfortunately I can't reproduce the bugs, since I receive them as crashlogs from clients' computers. Any idea if I'm doing something wrong at initialization?

Hi,

Any idea if I'm doing something wrong at initialization?

But.. What are you doing? :-) You didn't provide any code. Especially how you open and close devices.

But these errors are not bugs within the DryWetMIDI. They come from Windows MIDI system. DryWetMIDI just redirects them to you.
