Notes:
* The OPL4 chip combines an 18-voice FM synthesizer (same as OPL3) and a 24-voice Wavetable synthesizer (like the 4-voice Amiga Paula chip or the 32-voice Gravis Ultrasound).
* Unlike the [[Willy|Willy OPL3 and Willy MIDI]] soundcards, the AMSDAP with an OPL4 soundcard can [https://youtu.be/kahDREIaOog play Amiga modules] and [https://youtu.be/uKJdz2qLvoc PC wavetable modules (S3M/XM/IT)].
* And with the included YRW801 ROM chip and a software translation layer, the OPL4 can do Wavetable General MIDI. [[Media:Yrw801.pdf|YRW801 Wave ROM datasheet]]
