Apple IIgs Emulation SynthLab Audio Output Comparison
Video comparing various Apple IIgs emulators playing a SynthLab rendition of Yanni's Nostalgia. While most emulators have no problem playing back SoundSmith module files (2 oscillators per voice), SynthLab proves to be a bit more challenging to the various emulated implementations of the Ensoniq 5503DOC.
Shortcuts:
GSport 0.2 (KEGS): 0:00
MESS 0.148: 4:33
Sweet 16 2.2.1: 9:02
XGS 0.50: 13:32
Real ROM 01 Apple IIgs: 17:52
Summery of errors:
GSport: inaccurate and out of tune output, but timing is correct.
MESS: plays slightly too fast (emulator timing inaccurate) and DC bias hum on output.
Sweet 16 2.2.1: plays slightly too fast (emulator timing inaccurate).
XGS 0.50: plays way too fast (emulator timing inaccurate) and DC bias hum on output.
Real IIgs: The real hardware seems to drop a voice every now and then.
