Hi! I've installed blueMSX 1.5.0 and was wondering if and how it's possible to use the music cartridges from the CX5M in the blueMSX (or any other MSX emu)?
Could somebody give me some hints?
Currently when I'm inserting for example the SFG05.ROM and type call music, I get either a syntax error (MSX2 Mode) or just a nonchalant READY appaers (MSX2+ Mode).
Would be cool to get some info on that.Hi! I've installed blueMSX 1.5.0 and was wondering if and how it's possible to use the music cartridges from the CX5M in the blueMSX (or any other MSX emu)?

Yamaha CX5M computers have a special intern structure and there's no yet an emulator that supports these machines. The music Yamaha cartridges can only be used with these machines.

It's not a priority in the blueMSX development, because the support of Yamaha CX5M requires a more complete MSX-AUDIO support and Midi support. This could be made after Turbo-R support, because complete Turbo-R support requires too PCM support (also part of MSX-AUDIO Panasonic cartridge) and Midi support (see the Panasonic FS-A1GT)

WRONG - they're just like any other MSX1.

The music Yamaha cartridges can only be used with these machines.
WRONG - the only difference is they have a 60 pin slot with extra signals such as RGB. With a simple convertor (or official Yamaha UCN-01 adapter) the SFG modules can be used on ANY MSX.

It's not a priority in the blueMSX development, because the support of Yamaha CX5M requires a more complete MSX-AUDIO support and Midi support.
WRONG - the SFG modules contain a YM2151 chip (an already well emulated chip), they have nothing to do with MSX-AUDIO.

This could be made after Turbo-R support, because complete Turbo-R support requires too PCM support (also part of MSX-AUDIO Panasonic cartridge) and Midi support (see the Panasonic FS-A1GT)
WRONG - turboR PCM does not exist on MSX-AUDIO.

AFAIK only the Music Module has a second 'external' DAC which activation is controled by the aux-registers of the MSX-AUDIO.

And to be exact and if i am not wrong, the Music Module has an ADPCM out instead a PCM one.

No PCM on MSX-AUDIO ? It's correct for Toshiba and Philips cartridges, but not for the Panasonic MSX-AUDIO : his MSX-AUDIO BASIC includes PCM commands. See this Dutch page : http://www.mccm.aktu.nl/millennium/milc/gc/topic_26.htm

Other words of TheSpecialist :

"it's funny how you think the law works"

It makes me think that some people can use different nicknames to hide their real identity.

The above language is well-known from a MSX guru that is no more glad with MRC reactions. I let you guess who is this guy, but I have my idea about that.

Thanks for the precisions about Yamaha CX5M, but there are more gentle ways to do that: good info, OK, but also RESPECT of the other users ! Everyone can be wrong, including TheSpecialist ....

The Philips Music Module and some other MSX-AUDIO cart both have an external DAC to which you can send 8bit PCM data at the desired frequency. I can't remember which MSX-AUDIO cart this was, but I distinctly remember testing the function for a little game I made for the FutureDisk.

If you are referring to I/O port $0A... It's the Music Module.

You spoke of the PCM included in the MSX turboR. I spoke of 'turboR PCM'. I'm trying very hard to see the connection between 'turboR PCM' and MSX-AUDIO. The MSX-AUDIO 'PCM commands' most probably use ADPCM, not PCM. Even if it did use PCM, it is completely different from turboR PCM.

I can be wrong, but I was not. You posted a message completely filled with wrong statements, am I not allowed to clearly mark those statements as wrong? I don't see how correcting you is disrespectful.

I'm not sure who you are confusing me with, but I'm myself and no-one else.
I have monitored this forum for a long time and I must say it's turned very aggressive and ignorant lately. A lot of accusations and misrepresented facts!

If I'm not appreciated I will contribute elsewhere.
