I never thought you had closed the GUI 😀
The GUI is your Roland MT-32 device, if you close it, it's as if you turned it off... Well, not really since you still get it on your default output 😀

(Btw. Munt stuff belongs into MT-32 Development "MT32 Development" in the MDI Emulation category - Hopefully some moderator moves the topic - I don't have moderation power in Marvin)

Moved.

Oops, that's a miss.

Note, when you shutdown the GUI, a different synthesizer engine starts that is built in the Windows MIDI driver. Although, it is far from being fully compatible with the GUI, I see no reason for not using the DefaultAudioDevice property you set with the GUI. I'll fix that shortly.

However, there is only one Audio API available for the internal synthesizer engine of the Windows MIDI driver, so it'll use that audio device only if its name matches one available for "WinMMAudio" API (a.k.a. "waveout"). Best would be to select in the GUI the device you want that has "WinMMAudio: " prefix.

Sergey, I wonder how do we configure the settings of Windows Munt driver? Are the settings of Qt Munt shared with the driver, or do we need to use the old inf/ini file method?

Right, the Windows MIDI driver reads the settings which mt32emu-qt maintains. Obviously, being a light-weight version of the full-featured synth, not all of them have effect but most do. So, when a supported option is toggled in mt32emu-qt, it'll be applied in the driver further on (usually, a restart is the best way to ensure that but many options are re-read and applied upon re-opening the MIDI port).

I didn't understand. Was there any conclusion to this? Do I need the GUI open to use a different soundcard than default for Munt or not?

Currently, yes. Either you set the device you want as the default one in the system or use the GUI app to do the synthesis and output to a non-default audio device.

In a week, I plan to rollout a new release that will incorporate that feature. If you want to participate in testing, this page provides for a development snapshot of a MIDI driver that is able to use another audio device you select with the help of the GUI.

I downloaded stuff from the page you linked, but as for my computer, there's no change. Output while Munt GUI is not running, Munt outputs to default.

Just be sure to reinstall the updated driver 😉
