Please please please can you find this article and scan it in, or at least
pass on the issue number and pages so someone else can. If there really is
speech synthesis in the CX5M, this is the only use of Yamaha's CSM mode in
the YM-series chips I know of.
CSM is composite sinusoidal modelling, and disassembling the ROM (which I
desoldered last night, incidentally) may give emulator authors an idea how
to emulate the CSM mode in other YM chips, such as YM3526 OPL (part of
MSX-Audio).
It's bit 7 of register 14h in the YM2151 OPM and bit 7 of register 08h in
the YM3526 OPL.
