If you use a MSX1 machine or a C-BIOS machine, you must add a MSX Audio chip or Y8950 (without addition of a rom), in the Machine editor , then save the new machine, eventually under a new name; if you want to use the MSX-AUDIO BASIC, insert also a Panasonic MSX-AUDIO in a cartridge slot.


Stereo

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

Some MSXturboR demos use at the same time MSX-AUDIO and PCM to produce a stereo effect, that you can also enhance in the mixer.


Hear only MSX-AUDIO

- de-select the other soundchips in the mixer

- if you hear nothing, then take a look below


Hear MSX-AUDIO in stead of other soundchips

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

- use the MSX2 Only PSG machine after addition, in the Machine editor, of a MSX Audio chip and saving of the new machine, eventually under a new name; if you want to run a Compile game or diskstation or use the MSX-AUDIO BASIC, insert also a Panasonic MSX-AUDIO in a cartridge slot

To run a Compile disk game or diskstation and hear MSX-AUDIO, you can also use in blueMSX the following POKE without need to insert the Philips or the Toshiba MSX-AUDIO cartridge in a slot :
- start the emulated MSX with nothing in the slots and drives;
- when you are in MSX-BASIC, insert the Compile game or diskstation in drive A;
- type POKE -54,35:POKE&HF346,1:_SYSTEM and press on RETURN

PANASONIC (FS-CA1)

The unmodified Japanese cartridge has a special switch that you can activate in the Options/Emulation menu :

- when the switch is selected, you access to the built-in firmware that is also available in the Toshiba cartridge;

- when the switch is not selected, you come in MSX-BASIC and can use the extended MSX-AUDIO BASIC (it's like the MSX-MUSIC BASIC but CALL MUSIC is replaced by CALL AUDIO and it contains also extra instructions for ADPCM samples and extern musical keyboard)

- from MSX-BASIC, you can start the firmware by using CALL SYNTHE if you don't have already used CALL AUDIO

This cartridge is normally required to get MSX-AUDIO in stead of MSX-MUSIC or PSG with some Compile games and diskstations, without using a special poke. In case of rom games, it's better to insert the Panasonic MSX-AUDIO in slot 1 and the game in slot 2.


PHILIPS (NMS-1205)

The unmodified Dutch cartridge starts with the built-in firmare, unless you press on ESC when booting the emulated MSX machine.

From MSX-BASIC, you can start the firmware by using CALL MUSICBOX

If you use this cartridge to get MSX-AUDIO in stead of MSX-MUSIC or PSG with some Compile games and diskstations, you must normally proceed as following :
- start the emulated MSX with this cartridge in one slot and don't forget to press on ESC;
- insert the Compile game or diskstation in drive A;
- in MSX-BASIC, type POKE -54,35:POKE&HF346,1:_SYSTEM and press on RETURN

This special POKE can also be used in blueMSX without inserting the Philips cartridge or the Toshiba cartridge in a slot !


TOSHIBA (HX-MU900)

The unmodified Japanese cartridge starts with the built-in firmare, unless you press on ESC when booting the emulated MSX machine.

From MSX-BASIC, you can start the firmware by using CALL SYN

If you use this cartridge to get MSX-AUDIO in stead of MSX-MUSIC or PSG with some Compile games and diskstations, you must normally proceed as following :
- start the emulated MSX with this cartridge in one slot and don't forget to press on ESC;
- insert the Compile game or diskstation in drive A;
- in MSX-BASIC, type POKE -54,35:POKE&HF346,1:_SYSTEM and press on RETURN

This special POKE can also be used in blueMSX without inserting the Philips cartridge or the Toshiba cartridge in a slot !

Only 3 MSX2 games in rom format can use MSX-AUDIO when you insert the Panasonic MSX-AUDIO cartridge in slot 1 and the game in slot 2 :

Family Stadium
Labyrinth
Xevious - Fardraut Saga
