Re: Can't open selected output device required by VirtualMidiSynth

Well, you saw default because, just before the initial error message VMS switched to it.
But this new value (default) is not saved until you changed something and click Apply or Ok.

This is done on purpose, to allow users to select a removable device (i.e. an USB headphone) and be able to run VMS with or without it.
If VMS is started without the headphone, it runs with the new (and temporary) default setting; then, when started again with the headphone, this device is selected as output.

There's something to be improved: the error message could contain the name of the now-missing selected device, to let it clear what's wrong.
Sadly at error-time the device is missing, so it's name can't be retrieved from the system; it should be stored elsewhere... I'll have a look at it 😉

Re: Can't open selected output device required by VirtualMidiSynth

Thank you... that setting was default.

I selected the audio device and stopped getting the error.

I checked Window's default device and it seems to be set properly:

I don't have a clue on why this changed or what is happening... but thanks again!

Re: Can't open selected output device required by VirtualMidiSynth

That error refers to the analog output device (your audio soundcard), not the MIDI one.

It seems you've configured an output device that now is missing; it could be an USB audio card or an external HDMI monitor (with audio)..

Check the attached screenshot to see where this setting is placed.
I suggest you to select the device, unless you have a specifis needing to use a different one, so that VMS will always use the default Windows one.
