Feature suggestion: YM2612 PCM drum sound mapped to YM2151 FM channel. #79

I'm hoping to map a YM2612 PCM drum sound to a YM2151 FM channel. Use json to configure the YM2151 FM drum sound just like YM2612 to YM2413.

The DAC support of YM2612 to YM2413 conversion is done by specifying 0 for the F-Number. However, unlike other YM families, YM2151 does not have explicit F-Number registers, so the same method as the YM2413 cannot be applied. I would like to support this in the future, but currently considering how to handle it.

My suggestion is to map the PCM to the YM2151 FM drum patch, it should be much simpler.

YM2612 to YM2413 currently have an experimantal support for FM to RHYTHM mapping. At this moment there's no support for YM2612 DAC to FM mapping. That's not something that can be done immediately.

take your time.
