If VDMSound turn out to be a suitable option, I might help with coupling all that stuff. First of all, I trust you have MIDI fully working in Windows, that is it's available for Windows applications and not only in DOS sessions. That's a requirement for this sort of setup, and VDMSound essentially …

Anyway, I suppose it is emulated properly now. See Issue #82 on Github.

Well, yes, there is definitely a problem with the device registry on this system, otherwise the installer would work. I suppose, dosbox is not the only MIDI app of interest, right? If yes, a build with the integrated mt32emu would be a better solution.

Still, adding a bit of autotests is a good idea, and I hope I'll be able to find time for that next year 😀

So much for the "proper" way of installing drivers. Perhaps, we could study the installer log and probably fix the system registry (I blame it due to lack of knowledge about the real cause), but suppose this is not fun.

Well, my research is stuck. The error seems to be this one: ERROR_NO_MORE_ITEMS 259 (0x103) No more data is available. But I'm not sure what data is meant. Yet I cannot reproduce it on a clean system after upgrade to 21H2.

Hmm, no idea what's wrong. Also, the error code looks strange, unlike all the other codes I've got from PnP manager before, so will have to research a bit. In the meantime, clarification: this issue is about infinstall tool; it relies on the system PnP manager, hence God knows how it works; the …

It's quite possible some of those "computer music" sound effects are used there too. Well, I did it right when avoided quoting that "Internet" who said that this game required old-gen device 😒

Presumably, this is old MT-32 vs. new MT-32 issue (as some say on the Internet, I don't want to quote as googling is easy). What I don't completely understand is why the game worked fine in early days of munt when it was unable to emulate old-gen MT-32 properly. @JozMk.II Could you try it with …

these are hardcoded calls in the game that im reversing - im trying to figure out what the controller-nrs are and what the values or value-ranges are allowed If you are interested in details of the MT-32 MIDI implementation, then the standard MIDI specs aren't particularly useful.

I don't know for sure, as I didn't bother looking at the full disasm code. But again, the magic number "10" here would suggest that the code attempts to deal with the rhythm channel specially. As we both noted, part 9 does not exist, but there is a rhythm part that is specially addressed. And in …

but address byte1 is always 0 so its 0x03 - base address 0x00 - address byte1 0x?4 - address byte2, only the high nibble of this address byte is changed, low nibble is always 4 I still see no problems with that, assuming the parts are mapped to MIDI channels 2-9, and the game does not send bogus …
