I'm looking for old ms-dos demos with Roland MT-32/CM-32L support.

Does anyone know if such demos existed?

Thanks in advance.

Never heard of one. An MT-32 + MPU-401 was a rediculously expensive setup at the time, and when it got cheaper and there was the SCC-1 and other alternatives, Gravis Ultrasound was already there. And Amiga style tracker music was way cooler and more undergroundish than MT-32 "multimedia" music anyway. Nice music, but the mom&pop variety. It's hard to imagine a demoscene demo with MT-32 sounds. I don't say it's impossible, but somehow it's from a different culture. Play your best MT-32 song next to Jester's Cyberride or Travolta's Condom Corruption, and you know what I mean. No street credibility, no rock&roll.

At least some demos by The Phoney Coders featured music for Roland cards, not sure about MT-32 though

I've never heard of one, and the DOS demoscene was my wheelhouse, so if there is one I would be pretty surprised.

The closest I can come to a demo that uses "MIDI" was a DOS demo that supported the GUS via it's MIDI API (meaning, it loaded patches out of ULTRASND\MIDI). Name escapes me at the moment, but I think either the demo or the demogroup started with the letter S...

I thought there were plenty of 4k intros that had at least General MIDI sound, like this one: http://www.pouet.net/prod.php?which=482. Probably not the same thing though.

Some demos with Roland music here, here and here

All Roland sound devices should work the same. An MT-32 is basically just a midi synthesizer, which you would connect to an MPU-401 compatible MIDI interface.
The LAPC-1 is an MT-32+MPU-401 on a card.
Instead of an MT-32, any other general MIDI compatible synthesizer could be used, the software does not know the difference (unless they use some SysEx commands... they would get ignored by other devices).
And virtually all sound cards have an MPU-401 compatible MIDI interface, so that should work.

The GUS did not have a MIDI API as such, just MPU-401 emulation, redirecting it to the internal synth, which effectively turned the GUS into an LAPC-1'ish device.

Not DOS/MT-32 'native' but was my understanding Parsec used the Windows GM MIDI mapper - which means you could probably get it to use the MT as an external GM device? Record it for us if you get it to work!

MT-32 != GM, at least per default.

Thanks for the answers, guys. I've been playing a lot of old games recently, especially Sierra adventures on Dosbox with integrated MT-32/CM-32L support (SVN Daum build).

Here's some examples:

Police Quest II

Zeliard

Spacewrecked

Inferno: The Odyssey Continues

Lotus: The Ultimate Challenge

Hummm, knowing the Amiga music of Lotus Espirit Turbo Challenge make the one above sound really disappointing!

Monkeee! I did like the Adlib version, too.

sweet :)

I'd be very surprised if there was a demo with the custom sysex commands for the mt32.
Someone could have done a nice Gameblaster one as well.
