Premium quality MSX-music sound extension
The MSX Music sound cartridge has long been a favorite among MSX users. Originally introduced by Panasonic as the FM-PAC, this FM sound extension offers a richer and more realistic sound palette compared to the default MSX PSG chip. The hardware group Outer Heaven enhanced it further by designing a high-quality, low-noise version, and added it to the MSXdev25 loot box.
Playing MSX soundtracks directly from the original source through your speakers is a familiar experience for many MSX users. Often, it comes with unwanted noise and poor connections. Hardware group Outer Heaven solved this issue with the SixPac MSX-Music (OPLL) cartridge—pure brilliance.
The SixPac is a Konami-sized cartridge that features an external 3,5mm audio connection to tap those warm, authentic FM synthesis sounds directly from the device into your stereo. Or headphones, which ever you prefer. The high quality components used in the package deliver a crips, no noise, well balanced and eargasmic MSX-Music listening experience. It’s rock’n’roll time!
This item is so unique, it’s only sold in inner circles with a limited edition. Luckily, we got one and we couldn’t be happier to have this exclusive piece of MSX technology in our loot box. Combined with the cartridge comes the brand new Outer Sounds music disc, of naturally in full OPLL mode. Thank you very much Outer Heaven!
If you are interested in one for yourself, contact sixpacmsx@gmail.com and you might have a wonderful piece of MSX hardware in your hands. For more information and technical detail on SixPac visit Outer Heaven on their hub.
