I thought this might be of some interest.
Saku Taipale has the original Synthesizer cartridge. The original game
came with a tape, which he recorded to .wav, I've converted them to .cas.
I've uploaded the files to funet, dunno where they are now. But you can
also get them from:
http://www.msxnet.org/konami/Synthesizer/
The cartridge has a 8bit D/A which is accessed through memory mapped I/O
address 4000h. It's unsigned. The .cas files are simply short samples
which you can use in music you compose with Synthesizer.
So on linux:
$ play -t .raw -u -b -c 1 -r 11025 Synthesizer-Dog.cas
And you hear a dog bark.
MESS emulates this cartridge with D/A. You need the crc files to make
it work correctly (this is how mess knows it's Synthesizer).
