I have been noticing the reverse stereo of supposed effects in quite a number of games : King's Quest V town music when standing south of the big tree screen, GODS sound effects (especially the trap devices sounds which come from the opposite direction), Hero's Quest I (QFG) intro dragon grabbing the mountain, etc.

In my real MT-32, I just swap the RCA L & R wires at the back.

Is there any option in future to add reverse stereo sound option in MUNT?

Thanks for any information.

Edit : Using Debian, and compiled MUNT (mt32emu & mt32emu_qt) from source from Github.

In the Windows build, there's a checkbox in the properties menu to reverse the stereo channels. Is that option not present under Linux?

How do I get to the properties menu? I'm using the compiled mt32emu-qt executable in Debian. The menu in the main window shows Tools, Options and Help. Under Options, there is no checklist to reverse the stereo.

LCD display, meaning in the floating display?

Loading mt32emu-qt startup in Debian XFCE, and it's starting iconized. I have hidden the floating display. Enabling the floating display and checking out, there is no properties in the floating display either by right clicking or left click.

The only other executable that is compiled is the xmt32. Also there is no option for properties.

Any screenshot available? Thanks.

It's not that it's so hard. Just that this is what I see when I right click the icon on the panel and choose Show Main Window.

I just get the same window all the time. No LCD display.

Maybe it's got something to do with XFCE. Not sure.

Anyway, thanks for the screenshot.

Edit : Found it. Actually it's hidden under Tools ---> Test MIDI Driver in my system. *Shrugs*
