Minigsf To Midi [upd] «Web»

miniGSF

Converting to MIDI is a niche task common among video game music enthusiasts and composers who want to extract or remix music from Game Boy Advance (GBA) games. Unlike standard audio files, miniGSF files are a variant of the Portable Sound Format (PSF) that contains ARM program code and sequence data instead of actual waveforms. Understanding miniGSF Files

• Timing: Many retro formats use frame-based timing (e.g., 60 Hz). Convert frames to beats using tempo = frames-per-second × 60 ÷ beats-per-minute relation or set a tempo that preserves intended speed and then refine by ear.
• Arpeggios: Convert rapid note-cycling arpeggios to repeated short notes in MIDI or use arpeggiator plugins for cleaner results.
• Pitch effects: Use pitch-bend events with appropriate sensitivity; remember pitch-bend range must be set to match chip semitone span.
• Noise/percussion channels: Map to drum MIDI channel (channel 10 by convention) and use drum samples or synth noise patches.
• Nonstandard tunings: If the source uses detuning or microtonal shifts, approximate with pitch-bend or MTS (if your tools support it).
• Polyphony limits: If the original had limited hardware channels that rapidly reused voices, keep separate MIDI tracks to emulate voice-stealing behavior or manually edit overlapping notes.
