GMC-OPM: OPM Module

A module mounted with an OPM(YM2151) sound chip.

OPM is an eight-channel, four-operator FM sound chip.
It differs from the OPN series in that it has hardware LFO and the DT2 parameter.*1
These grant OPM a wider range of sound creating possibilities.

*1 OPNA does have hardware LFO, but it's somewhat rudimentary compared to that of OPM.
*2 To use G.I.M.I.C as an external sound source for X1 emulation, you can connect two or more G.I.M.I.Cs to your PC for more faithful reproduction.
*3 G.I.M.I.C with the USB-controlled firmware does not play ADPCM sounds; they are played with the PC's sound card instead.
*4 Mounting OPP will not bring any change to the module's function.
