Note: Unlike Like the MIDI synth functionality of the [[AMSDAPRSF3]] OPL4 & YRW801 ROM solution, the S2P soundcard natively supports Wavetable MIDI without requiring . It doesn't require a software translation layer. The Willy with S2P soundcard recreates what it was like to connect an Amstrad CPC via a the [[Music MachineAMSDAP]] MIDI port to a Roland MT-32 synthesizer in 1987OPL4 & YRW801 ROM solution.

== I/O Ports ==
2 ports are used to control the [[MIDI ]] soundcard: &FEAC for data, and &FEAD for control and status. Sadly, that means it is not compatible with the [[EMR MIDI Interface]] which is located at ports &F8F2 and &F8F3.
3 ports are used to control the OPL3 soundcard: &FEBC and &FEBE are register select ports, and &FEBD is the data port. Again, we can regret it doesn't use the same ports as the [[AMSDAP|AMSDAP OPL4]].
