Cost

The cost for a Willy soundcard adapter is 10€. This does not include any soundcard, you have to buy those separately.

Technical information

2 ports are used to control the MIDI soundcard: &FEAC for data, and &FEAD for control and status.

3 ports are used to control the OPL3 soundcard: &FEBC and &FEBE are register select ports, and &FEBD is the data port.

OPL3 offers 18 FM 2-op chans. One setting converts 3 of the FM channels into a 5-channel percussion set. Another setting pairs 12 of the FM channels into 6 FM 4-op channels.
