Msx audio automaticly switches to other port if there are 2??

No, it is not quite that easy, but not hard either.

=== WARNING: UNTESTED ===
Looking at the Philips Music Module schematics it seems that you need to cut the line going to IC9 pin 12 and connect the line to pin 13 instead... I would say it is good idea to use a switch here.

Um, no, I don't think so. AUDIO2 is on 0xC2 and MoonSOund on 0xC4 and 0x7E. But I see what my mistake was... my vu-meters script in openMSX doesn't support the FM part of it... so it's probably working fine Smile

Yes, this works fine on openMSX... I was actually very surprised that the FM-PAC was working correctly out of the box! As far as I know there is not a single program EVER made that would use both MSX-MUSIC and FM-PAC at a same time... and yet it was emulated correctly. I'm impressed!

You are programming to the edge as usual, indeed some weeks ago, somebody did a similar test
and posted about it in msx.org forum

Ah, sorry... I totally missed this conversation... Well, I wasn't the first then this time, but it was a close call considering that this is a 30 years old device. I guess I have to be faster next time. ;)

raymond: those are on the same I/O ports, so it's the same as using 2 Music Modules.

I thought the Panasonic MSX Audio was auto switching. But thinking about it, you are probably right.

Nice, a second peace of software that uses the AUDIO 2. Only problem is that when a have a few more songs in the directory I get an Out of string memory error. Anything I can do about that?

Oops, that's my bad... try to write something like CLEAR 3000,&HD800 and run the program again.

The Panasonic FS-CA1 has I/O port auto-configuration. The BIOS each cartridge will check the available I/O ports in the C0h~C3h range and configure the cartridge accordingly. AFAIK, openMSX is already emulating that.
