( Any GUI application ) Refer to http://www.3dsoundsurge.com/archive/week16.htm (iii) OPL3 Support: Both Windows DOS boxes and real-mode DOS now support 4-operator OPL3 FM synthesis, in addition to 2-operator OPL2 FM synthesis. 6) Do au88x0 support OPL3 ? The "vortexcontrol" use alsa-lib API to play the audio samples inside au30gm.arl through hw:0,0. 7) How can the audio sample be played within the driver using the soundfont through hw:0,0 in a 16 voice synth for au8810 (without WT) ?
