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 is register compatible with OPL2, with twice the number of signal sources, 4 new operator modes, 4 new selectable waveforms and stereo output.
OPL3 offers 18 FM 2-op chans in its standard mode, but that can be configured:
- One setting converts 3 of the FM channels into a 5-channel percussion set (Bass Drum, Snare Drum, Tom-Tom, Top-Cymbal, Hi-Hat)
- Another setting pairs 12 of the FM channels into 6 FM 4-op channels
- Both settings can be used at the same time
Also, a square waveform can now be selected on each chan. So the OPL3 can play square waves like the PSG.
