If there's one hardware extension for MSX that really made an impact, it is without a doubt the Panasonic FM-PAC. A sound extension that delivers 9 FM channels, known as MSX-MUSIC. Before the FM-PAC there was another extension called MSX-AUDIO, the most popular version was the Philips Music Module. While the FM-PAC was used widely in Japanese MSX games, the Music Module was the thing to use in the MSX demo Scene. This device is still a collector's item. Now the Brazilian company Tecnobytes presents a MSX-AUDIO device, comparable to the Music Module.

If you know the MSX demo scene, you sure are familiar with the MSX-AUDIO sound. Pioneers like the FAC gave us a peek of what was possible with the the Music Module. The ADPCM Sample Ram was a thing, back then. Later on the 9 FM channels, just like the FM-PAC, were explored deeper and dedicated music editors came to the scene. Those editors made it possible to combine the sample ram with the FM channels and give us some really cool tunes to dance to. Remember Moonblaster, perhaps the most popular tracker of all. The sample RAM was limited, so clever minds adapted the Music Module to have 256K or RAM. Demos like NOP's Unknown Reality took heavy advantage of that.

Since it is hard to get your hands on a Music Module, the Brazilian hardware developers at Tecnobytes decided it was time for a worthy clone. A tribute to the original piece of hardware. And it's called Audiowave. A cartridge fully compatible with the MSX AUDIO standard. The size is a lot smaller than that of its older brothers so it'll fit nicely with your other extensions.

We are talking:

  • Y8950 sound chip with 9 channels of FM synthesis
  • 4 bit ADPCM channel, with max16 Khz resolution.
  • 256 KB Sample RAM
  • 512 KB FLASHROM, allowing BIOS upgrade.
  • 32 KB WorkRAM
  • The MSX-BASIC extension and musical keyboard software in ROM.
  • Line Out Jack P2.
  • Line In Jack P2, used for audio capture.
  • Connector to use compatible musical keyboards, such as YAMAHA YK-01, YK-10 and YK-20, Panasonic FS-MKB1, TOSHIBA HX-MU901
  • Compatible with all MSX standard machines

The price of apparatus is USD 82,00, ex shipping. If you want to get your copy, you can now pre-order Audiowaves.

The MSX-AUDIO is not just a rarely used piece of sound extension, no. There is a lot of MSX software out there that benefits from this unique sound chip. This is your change to get back to the nineties and swing your head on them MSX-Audio tunes like never before. Hit it!

I saw this on the tecnobytes site a couple of days ago, was really tempted to order one. But then I thought, when was the last time I used my Philips module...still tempting though. Really nice small format.

I think it's a good choice for People who don't have a music module, want the genuine sound, play with keyboard and need the smaller format. Plus; not having to solder in the Music module for extra ram or MSX-Audio bios is also a plus.

I already have 2x philips music module with 256KB, this one might be interesting though because of its smaller form factor

It would seem its compatible with *any* keyboard? iirc normally the keyboards are not interchangable
This one is lacking midi though unfortunately, but then again its not part of the MSX audio standard.

Although quite a lot of the MSX Audio songs can already be replayed on OPL4, it's nice to see this new hardware release. Especially with the ability to update the BIOS and connect a real keyboard. Although not often used, the 256K sample ram is a nice bonus :-)

I think that’s very cool! Philips and Toshiba modules can still be found but are getting more expensive, and usually don’t have the memory upgrade or MSX-AUDIO BIOS. Plus it’s a nice compact form factor. And the ROM is flashable. Having the Yamaha type keyboard connector’s also nice.

I'm a lot interested in the 256kBytes od ADPCM. I think Yamaha OPNA can use same amount of ADPCM RAM of MSX-AUDIO, possibly also the capability of OKI MSM6258 ADPCM chip of Sharp X68000. Uhm...

FS-CA1 seldom appears on the market so this one is very welcome. It can also boot the FS-CA1 software that the upgraded NMS-1205 cannot. Only thing it lacks is NMS-1205's MIDI interface.

Sorry for Tecnobytes but I cannot agree with you because it's really a shame to make a cartridge of such a level and to put tinned contacts coarse.

Heard back from Tecnobytes. They are finalizing production and hope to start shipping in a week or two.

I hope to hear about audio quality. I have requested the recording sample (not from microphone like on their youtube video but from line in) to check if i'll be interested or not but had no response since. Now the batch is over so i will stick with my old good Philips module, but i'm still curious about the audio quality (noise level at least, because other things like crosstalk between channels need more effort and sometimes patching the vgmplay)
