Midiary: MIDI File Studio

Midiary is an offline workbench for Standard MIDI Files: open a .mid, see everything inside it, audition it, and export it cleaned. INSPECT - Format, division (metrical or SMPTE), track count, duration, byte size - A real tempo map — every change plotted and integrated, so tick 9,480 has a correct wall-clock time even across three tempo changes - Time signatures, key signatures, and markers, each placed in time TRACKS - Per-track cards: name, channels, programs, note count, note range, controller and pitch-bend counts - Findings per track — including hanging notes, detected by actually matching every note-on to its note-off PIANO ROLL - Every note drawn to scale, coloured by channel, velocity as intensity - Zoom from overview to detail; octave guides and time rulers - Hanging notes drawn in warning orange, running to the edge EVENT DESK - Every event in the file with tick AND seconds, filterable by track and kind - Note names, CC numbers, program changes, pitch bend values, meta text AUDITION - Built-in playback with a transport bar, so you can hear what you are reading EXPORT - A cleaned .mid: End-of-Track repaired, hanging notes closed, every status byte explicit for maximum portability - The complete event list as CSV for spreadsheets or scripts Everything runs on this device. No account, no uploads, no tracking. Import a file and the app tells you the truth about it — including what is broken.
