The Roland MT-32 Lossless Archive has had the MT-32 version for over a year now. Why didn't they just use that? 

What I was speaking of is the melody played on channel 4.

That's actually not the lead guitar I'm speaking of, but I did notice the bass didn't sound right either.

Correct - TFX was composed on an LAPC-I, so it'll only play on those and CM-32Ls.

The FLAC is shorter since that was recorded at a later date from the editor than the MIDI file - I simply kept the MIDI file going a bit longer (it just plays more of the loop point).

Eh, it still sounds really odd playing TFX on it compared to a real CM-32L.

The lead guitar certainly sounds wrong in 'Defence Suppression' - I have a MIDI file and real CM-32L for comparison:

FLAC recording

Then again, the bass drum doesn't sound right either.

I actually notice the SC-55 sounds a little crisper.

At the moment I'm playing with the CM-32L in overflow mode to a CM-64, since several of Barry's tracks eat a lot of poly.

Barry originally composed it on an LAPC-I then converted it to the SCC-1 and Sound Blaster (which he hated). The SCC-1 version ended up becoming the CD version, although 'Close Air Support' somehow got broken on the CD version.

I'm still working on recording that version from my SC-55.

(Here's the version recorded on my Audigy 2 ZS if you want to hear it - this is recorded from a CM-300: http://la32.co.uk/dreams/pc/TFX_Original_SCC-1.7z )

Some more from the CM-32L:

TFX / Tactical Fighter eXperiment - Part One | Part Two (I consider this the best MIDI soundtrack of all time.)
European Champions

And not related to the MT-32, Inferno recorded from the new SC-55 I scored on eBay. Unfortunately, it stinks of cigarettes.

I'm unsure. I haven't tested the optical/coaxial digital-in yet - I need to get a new cable to try the AWE32's S/PDIF out.

I guess I should chip in. Recently got given a TerraTec DMX 6Fire USB sound card, so I've been slowly updating all my recordings.

Ones done so far, recorded from the Ocean MIDI editor (MEDIT) & CM-32L:

Inferno
Jurassic Park
One Step Beyond
Utopia

I finished recording the original version of 'The Humans' last night, and I've started to wonder why very few composers used the echo/tap-delay setting on the reverb chip. Barry Leitch, Ian Howe and Dean Evans are the only composers I know of who used that setting, and they were all from the same company. They used it pretty heavily, too. I have never come across any other composer that used it on the MT-32 or LAPC-I.

Does anyone else know of composers who used it? Was it not used much because composers didn't like the sound of it?

No, they use the same adapter that the MT-32 and other CM modules use. I've never had a problem using the original adapter on my CM-64 that came with my MT-32 and CM-32L - they're both identical and rated for 1200mA.

I'm pretty certain the soundtrack was composed on a SC-55. I've listened to all of the MIDI files on my CM-300 and they all sound 'balanced', while any other device I play them on (Ensoniq Soundscape Elite and Yamaha MU10 for example), something generally sounds 'wrong'.

A very late reply, but this is a superb conversion! I would certainly love to hear more of Descent's tracks on the MT-32.

Wow, blast from the past. I never did figure this out and I haven't actually touched one of these cards in over three years (using XP x64 which doesn't support the card at all).

Unfortunately, IE6 never had support for transparency on PNG files and 7 was mostly broken. Even more unfortunate is that 20-30% of IE users still use IE6. 

Chrome, Firefox and Opera should be fine.

I *think* the MU50 is just a DB50XG/MU10 but with the front panel and LCD screen.

Very tempted to get the PSP version.

Recordings re-uploaded and added a lot more in that I've had laying around for a long while.

Will take me a few hours to re-upload them. Had a large clean out on my web host.
