DOOM OPL3 cannot realize multi chip recording VGM

[denjhang]

I tried a 4op instrument. When playing a MIDI that may be more than 16 polyphonic, there will be a phenomenon of note crowding, that is, the note played first cannot last. When I turn on 2-chip simulation, this phenomenon can not be solved, and the recorded VGM is still a single chip.

Multi-chip support is only available in the extended Doom driver. I couldn't seem to port the features that I added to the driver to the extended version.
