MT-32 Emu Not Playing Back With the Expected Sounds

Help!

I am trying to relive my childhood youth where game were games and not some mindless FPS. Anyway I though I would revisit all my sierra game, but this time I wanted to hear them the way they were meant to be heard. So downloaded and installed Munt 0.1.3, and I “obtained” the Roland MT-32 ROMs with the exception of the CM-32L, but I have the concatenated versions of the both of them (the hash marks are the same as listed on this site.)

When I go to play the games, right now I am playing Quest for Glory 2: Trial by Fire the music does not sound like what other people with Roland MT-32 sound like. People have posed numerous music comparisons of games, (believe me I tired all the ones that I have, that were also available to sample here and at Quest Studios) but the music always sounds like it is using the general midi sounds.

I have read the documentation, and I have the games working, i.e. it doesn’t bitch that it’s unable to detect the audio hardware. I must have missed something. I don’t think its with DosBox because I am unable to play the midi version correctly even though I am using the MIDI:win32 selected MT-32 Synth Emulator

This file is a generated raw wave file from Munt 0.1.3 I think this may be the problem, can someone verify it against what they have.

if you want to hear it, like it was ment to sound, you should better get a REAL
mt-32.

in my opinion those mt-32 emus dont realy sound like the real thing.

i also first tried those mt-32 emus, and i was dissapointed. after that i get a mt-32 from ebay.. now im happy.

lfo2k is right. Occasionally I'll work on the emulator and the current build of Munt is quite a few iterations behind my current work. However, very few people seem interested so I see little point in posting what changes I've made (because it's like a Rubix Cube... fix one game or instrument and another one sounds funny!). That said, the latest version doesn't use the generated files at all but generates the analog sounds on-the-fly.

At some point I might get around to posting my changes, but at this point I'm frustrated too because no one seems interested in getting the MT-32 emulation right, but rather wasting their time getting it compatible with the CM-32 or CM-64, way before the MT-32 emulation is dead on.

If I knew what to say to give you a boost then I would!

I agree that MT32 emulation should be the priority as that's what you started so that's where effort should be spent. When that's taken as far as it can go then other lesser used hardware can be considered.

I'm sure there are many like me who really appreciate the effort you've put in. I'd hate to see this all wasted with a 75% complete solution. If there's anything specifically that anyone can help you out with then ask away - perhaps people need stimulating into action 😀

Even though I have a real MT32, I still want to see the completion of this emulator. I would like others to be able to share the experience of playing some of the old classics with the music the way it was meant to be. Besides, my MT32 won't last forever. I say ignore the rest until the MT32 emulation is complete and thanks for your efforts.

Yeah, I would also love to see Munt updated. I've never owned a MT32 (nor knew anybody who did), I enjoy playing old games with all the new music

I compiled CVS a month ago and it was an improvement, with significantly better tuning (finally!). Some notes were off, but I think difference was in discrete number of halftones.

I hope sound quality will eventually become closely comparable to real MT-32 - and that you will find motivation for it, Canadacow 😈

Even if it's not 100% close to a real MT32 (can't compare it) it sounds
really cool. Having an interface to ScummVM and DOSBox, it reaches
a large audience.
I really hope this thread contributes a bit to keeping up the interest on
working on Munt! So far it is already a remarkable achievement.

Besides myself being interested in your project from the get go, having ScummVM supporting your engine should be an indication of interest.
On the forums of ScummVM there are posts about asking for correction of sounds in Loom, etc.

Count me as another one who has never seen nor heard a MT-32 in the real life. I've only seen a few photos and listened to some mp3 files downloaded from Quest Studios.

When Microsoft included their (well, to be fair, Roland's) Sound Canvas emulator in DirectX for free, I was completely blown away. I was used to the crappy music of my soundblaster 2.0 card and I was stunned by the difference.

A 100% accurate MT-32 emulator would be an important achievement. And I'm sure that many people will also be blown away like I will be when I can finally listen to it 😉

Thanks a lot for your efforts canadacow!
Regards.
