MSX-MUSIC is a light version of MSX-AUDIO without sample unit , it's the Yamaha YM-2413 OPLL FM sound synthesizer with 9 channels of FM sound without drums or 6 channels of FM sound + FM drums.

To hear MSX-MUSIC, the emulated MSX machine must include a MSX Music chip (with addition of a rom). It's the case of all generic MSX2, MSX2+ and MSXturboR machines, with exception for the MSX2 Only PSG machine.

The FM-BASIC is an addition to the MSX-BASIC, it allows to use easily MSX-MUSIC, but you must insert a MSX-MUSIC chip in a slot to access to the new commands when using a machine without built-in MSX-MUSIC.


If you use a MSX1 machine or a MSX1/MSX2 C-BIOS machine, you must add a MSX Music chip.

The most simple way is to use the normal or special cartridge menu to insert a MSX-MUSIC cartridge in a slot, but you can also make this addition in the Machine editor , then save the new machine, eventually under a new name.

For the C-BIOS machines, it's recommended to use the cbios_music.rom file that comes with the MSX2+ C-BIOS machine : see this page.


Many demos use at the same time MSX-AUDIO and MSX-MUSIC, what gives a stereo effect, that you can enhance by a fine tuning in the mixer

Hear only MSX-MUSIC

- de-select the other soundchips in the mixer

- if you hear nothing, then take a look below

Hear MSX-MUSIC in stead of other soundchips

- de-activate the MSX-AUDIO emulation and/or the MOONSOUND emulation in the Options/Sound menu
