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).
* 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]]
* Unlike the [[Willy|Willy OPL3 and Willy MIDI]] soundcards, the AMSDAP with an OPL4 soundcard can [https://youtu.be/kahDREIaOog play Amiga modules] and 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]]
Also interesting is a new MSX soundcard, the [https://www.msx.org/forum/msx-talk/hardware/vfm-virtual-full-music-msx-universal-audio-cartridge vFM (Virtual Full Music)] that emulates many soundchips (SSG, OPLL, OPL2/3/4, OPM, OPNA, SN76489, SAA1099, SCC) by using a [https://www.pjrc.com/teensy/ Teensy board]. It also includes a PCM (PCM5102A) chip and a MIDI (SAM2695) chip.
