Error initializing MIDI output device

[francheton]

Hello,

I just upgraded my PowerTabEditor from 1.7.0 to 2.0.0 alpha 10 under windows 10.

When I load all the .ptb files I previously build with the older version, I obtain this message :

"error initializing MIDI output device"

=> Who can help me ?

Best regards.

Can you link/attach an example of a ptb file that causes the crash?

I am experiencing the same problem. when I got to set the midi output device /File/Preferences/Midi there are no items in the drop down for 'Midi Output Device'. Any help would be much appreciated.

thanks,

Hi @alfredowl , have you fixed somehow? I have the exact same issue, I tried installing a MIDI mapper and a MIDI synth, but nothing changed...

Ok, looks like there's something wrong in beta 11. I uninstalled and re-installed beta 10, now it plays! In File > Preferences > Midi Output Device I can see a device, where in bete 11 there was nothing.

Interesting, I'll see if I can reproduce the same in my windows VM. I think the main thing that would have changed in alpha 11 was upgrading to a newer version of the RtMidi library

@cameronwhite Thanks for looking into it. Also, beta 10 plays fine, but can't open my old PTB files (PowerTab 1.7), I can send you privately an example via email if you like. The same file opens fine with beta 11, so I tried to save a PT2 from there and open it in beta 10, but it fails (but I guess it's normal since it's an older version of the saved file...?).

[cameronwhite]

Yeah, I think the file format version number was bumped in alpha 11 due to adding left hand fingerings. I wasn't aware of any issues that were fixed with opening old ptb files, though, so I'd be interested to see a file that had an issue

[joeSeggiola]

@cameronwhite Ok, I'm sending it to you now, to the email I see on your GitHub profile.

I think the file format version number was bumped in alpha 11

Yes, I saw that "version": 4, I tried to manually change to "version": 3 (a man can hope!) but it didn't work... 😄

[cameronwhite]

Thanks, got the email!

Same problem with Alpha 11 on Windows 10. I uninstalled and installed Alpha 10 and playback works fine.

[cameronwhite]

I can repro on my VM and am looking into it

@joeSeggiola - Based on the file you sent, I think the issue opening that file in alpha 10 is the non-ASCII characters in the file name, which #244 fixed

[cameronwhite]

Ah, I think the issue is that the vcpkg build of RtMidi isn't configured correctly - microsoft/vcpkg#6993

[cameronwhite]

OK, the midi issues on Windows should be fixed now!
I've updated the alpha 11 release with a new Windows build that incorporates those changes.
