Roland Backs Down On MT-32 Emulator

canadacow writes "This is a follow up to the cease and desist letter the MT-32 project received (Original Story). Roland, unable to find documentationg establishing a copyright on the MT-32's ROM, has yielded to the project and allowed distribution of the emulator to continue. On my page www.artworxinn.com/alex I've again posted the emulator along with the legal developments as they happened after the receipt of the initial C&D letter. This development was largely due in part to the legal support of the Electronic Frontier Foundation."

Not a win for OSS

Before you all get excited about this, note that this is not a win for OSS -- not really. Notice that no legality was established. Roland simply gave up because they have not been able to find their documentation establishing copyright.

Re:great, now we can all freely emulate MT32s..

A professional synthesizer module produced by Roland during the mid to late 1980s. It had 128 built-in samples, but could also store custom samples using LA synthesis based on the existing samples. It's most desired by fans of older computer games; many games, especially adventure games, prior to about 1992 were written specifically for the MT-32. Since no other devices (other than a few devices based on the MT-32, also by roland) can play MT-32 MIDIs properly, they're quite desirable especially to fans of Sierra and Lucasarts adventure games, as well as fans of the Ultima RPGs.

Since they couldn't find the copyright of the ROM, it seems it can be freely distributed.

It's not a keyboard, it's a sound-module. i.e. it's the part which generates the sounds but doesn't have any keys on it to play and is controlled by another MIDI device.

It was an important product in it's day since it was the first multi-timbral (hence MT) synth meaning it could play more than one instrument at a time (e.g. piano and trumpet). The 32 refers to the maximum simultanous voices of the device. Each instrument uses between 1 and 4 voices, so the actual polyphony was between 8 and 32 depending on the instruments you were using. If you had two MT32s you could daisy chain so overflow notes go to the second device.

As others have mentioned they were supported in various games, like the Sierra adventures. My personal fave was X-wing with the MT32 (music) + Soundblaster (effects) setting.

MT32s are pre-GM (General MIDI) so the instrument mappings are non-standard (luckily the drums are the same). Various MIDI devices will have a MT32 mapping mode, so MIDI files will sound about right but for the real effect you'd need the real device.

The tone generators were a hybrid of FM generation (i.e. sawtooth waveform etc.) plus a limited amount of sampled data.

Actually, an early-days PC sound card. Check this out:

" Serious game music for the mainstream user on the PC started with Sierra back in 1988. Before this, PC's were only equipped with a tiny beeping speaker. Sierra prepared to change all this by creating games that contained serious, high quality musical compositions drawing on add-on hardware. Sierra struck a deal with two companies, Roland and Adlib. Sierra adopted the Roland MT-32 and the Adlib Music Synthesizer. They would compose music for these units starting with King's Quest 4. Sierra would also become a reseller for these units.

The Roland MT-32 was the higher end of these music devices. In today's terminology, it would be labeled a "Wavetable Synthesizer". A wavetable synthesizer usually implies that real instrument sounds are recorded into the hardware of the device. This device can then manipulate them to play them back at the various notes you need. This may not be the most accurate description as the MT-32 had the ability to manipulate parts of its built in sounds using something called "Linear Arithmetic (LA)" synthesis. Technobabble aside, it was a very good device that can rival even today's sound cards (though Tom and other MT-32 users will be quick to point out the lack of a built-in piano patch). It was also a very expensive sound card, costing $550 through Sierra. " (quoting an article by Eric Wing)

I saw one of these things, in the beginning of the 90s, at a friend's house. It was really high end... and he used "Leisure Suit Larry" to demo it (!). Anyway, this MT-32 emulation effort will probably be interesting for running the golden DOS-era games (many abandoware, check Home of The Underdogs).
