MIDI Converter follows mason369/midi-encoding-converter: it rewrites existing MIDI text meta-event encodings to the selected target encoding in the browser, with UTF-8 as the recommended default, without upload or model inference.
The MIDI converter is the mason369/midi-encoding-converter path for rewriting MIDI text meta-event encodings; it is not an AMT or model-inference tool.
Official repository - current
The converter repository documents the binary MIDI parsing path: parse MThd/MTrk chunks, find text meta events 0x01-0x07, decode source text bytes, re-encode to the target text encoding, recalculate track lengths, and write MIDI output. No neural paper or model ranking applies.
No public paper link is listed; use the official repo or adapter implementation as the source.

Used when auto-detect is off. Applies only to MIDI text meta events, not notes or timing.
Browser-local mode writes the selected target encoding: UTF-8, Shift_JIS, GBK, Big5, EUC-KR, or ISO-8859-1. UTF-8 remains the recommended default for modern DAWs and MIDI editors.
