Hi,

Does anybody know if the MT-32's PCM list is documented or not? If so, is there any info on where the document is?

Regards,

David

Here is some information that I'd compiled several years ago. The 128 waveforms in "Bank 1" pertain to the MT-32; the list for which was provided by Roland Japan.

Hi Cloudschatze!

Thanks for the spreadsheet. It really helps a lot!

Anyway, just for the sake of curiosity, do you have any information on where the list is compiled from which document?

Regards,

David

The information from Roland Japan was provided as a typed list in response to an e-mail inquiry I'd made back in 2005. I imagine it came from some internal documentation of theirs.

I didn't discover this until several years later, but Roland did provide an "official" source listing of the MT-32 waveforms in a supplemental manual that they published back in 1988:

Interesting. Until now I assumed that since the CM-32L was basically an MT-32 with additional built-in sound effects, the original MT-32 wouldn't have a lot of those.

Hope I'm not misunderstanding the comment, but just to clarify, the "Bank 2" waveforms in the spreadsheet do not apply to the MT-32.

Ah, yes. I missed it at first, but now I see it. Timbres R31 through R64 are indeed labelled as being available only on the CM-32L, LAPC-1, etc.

Amazing. That manual is really useful, it contains many information for using the MT-32. Thanks, Cloudschatze!

Hope the PDF will help someone on programming the MT-32.
