- When running the game that uses MIDI music in Hourglass, the above build will create midilog.txt in the game directory.
- Put it near midi.lua and execute the script (just drag'n'drop it into fceux or run via lExecutor). midilogra.txt will be created.
- Run midilogra.bat. midilogra.mid will be created.
- Put that file near fluidsynth binaries, along with whatever soundfont you want to use (natt used WeedsGM3.sf2 for Nikujin and Spyman), and run fluidsynth -F outfile.wav soundfont.sf2 midilogra.mid.
- You can preview the soundfont (and convert to wav) in foobar by installing BASSMIDI, just disable all the looping in MIDI synthesizer host options.
- Mix the resulting wav file with audio you got from hourglass AVI (time shift may be needed?)
