To Midi - Minigsf
| Problem | Cause | Solution | |--------|-------|----------| | MIDI file sounds like random notes | VGMTrans or pitch detection misassigned synthesizer parameters | Map the MIDI to a General MIDI soundfont and manually adjust program changes (Ctrl+1 to Piano, Ctrl+34 for Bass, etc.) | | Tempo is wrong | MiniGSF includes tempo micro-tuning not exported to MIDI | In your DAW, manually tempo-map the MIDI using the original MiniGSF as an audio reference | | Missing drum track | Percussion often uses separate “rhythm sequences” not auto-exported | Check VGMTrans for additional SSEQ chunks. Export each as its own MIDI track and merge | | Artifacts or hanging notes | Loop points in the MiniGSF cause infinite repeats | In a hex editor or audio editor, trim the end of the captured stream or edit the MIDI’s note-off events |
Since direct conversion is impossible, the practical method is: minigsf to midi
This is the "easiest" method if the tool supports your specific game. | Problem | Cause | Solution | |--------|-------|----------|
