It would be cool if they canl deliver the MSXPC with an card that has
OPL4 support in hardware. That would make it a bit more of a MSX PC for me.
Because plain cards with an OPL4 chipset can not be ordered anymore
(Like the Sound Man Wave from Logitech, TBS 2000 from Turtle Beach or the Yamaha Sound Edge SW20) we need an alternative.
The ALS-4000 Chipset from Advance Logic has hardware support for OPL3 and OPL4.
Here are the technical specifications of that chipset:
Avance Logic ALS-4000 Integrated PCI Audio Accelerator Chip
