I recently found out that, contrary to what I have always believed, the LAPC-1
is not a repackaged MT-32, but actually closer to a CM-32L. From what
I hear, the CM-32L was released after the MT-32, and was improved
somewhat (more RAM or ROM, extra sounds). Most of the information I've
found on the LAPC-1 says that its specifications are 100% identical to the
CM-32L, but there is one source (A 10 year old Roland FAQ posted to
USENET) which says that the LAPC-1 is a CM-32L with even more patch RAM
and enhanced sound effects:

Does anyone here have manuals for the CM-32L and the LAPC-1 so I can
finally know the truth? Are there differences between the LAPC-1 and the
CM-32L, aside from the former being an internal ISA card and the latter
an external box?

The LAPC has a bit more percussion sounds IIRC, and that's about it. Exact same ROM and RAM size specification (512kb and 64kb respectively) I am almost sure.

Okay, I did some more searching on the web and apparently, the LAPC-1 has
128 sound patches, 34 drums and percussion sounds, and 33 sound effects.
Does anyone have the numbers for the CM-32L?

Sorry, that was not exactly correct. The number of preset timbres in the
LAPC-1's rythym section is 30, not 34 (four of them appeared twice),
which is exactly the same as the MT-32. The LAPC-1 and the CM-32L both
have the extra 33 sound effects that the MT-32 does not have, though.

Having found no evidence of differences between the CM-32L and the LAPC-1,
I'll conclude that they are identical -- for now. :-)
