I wrote this in MIDI using MaliceX's OPL3 (user mode) MIDI driver, then played it back on Windows 3.11 in a DOSBox mod to log .vgm files. You can hear the lag particularly at the beginning, even though I set the CPU cycles to 32000. :x

Fun fact for nerds: I had to write the vibratos in this manually using the pitch bend controller, since the standard OPL3 MIDI sound bank didn't support vibratos made with the modulation wheel controller (CC#1). Yay for more resource hogging commands! :D
(Hence the uncompressed .vgm log of this is also relatively big, for OPLx .vgm standards anyway)
