Setting volume model to "CMF" mutes the song

[freq-mod]

It kills the music almost as soon as it's toggled.

Sorry if it is more libOPNMIDI bug rather than this player's.

The "CMF" model is just mapping the volume level over the chip native volume model directly, but, unlike OPL3, OPN2 has worse curve that needs to make the counting of volume from 65 to 127 rather direct mappings that I made with DMX and 9X models

[freq-mod]

So, if I understood correctly, this thing assigns MIDI volume levels to OPN carrier total levels 127-64, like it was OPL3?

If yes, no wonder it's broken

I tweaked all volume models, so, they do use the 64-127 range instead of being scaled to the full range.
