Midiary: MIDI File Studio

Midiary: MIDI File Studio is a focused, fully on-device app. An offline Standard MIDI File workbench for track and event inspection, tempo maps, piano-roll visualization, timing conversion, channel summaries, playback, and clean exports.

KEY FEATURES
- Open SMF format 0, 1, and 2 files from Files
- Decode variable-length deltas, running status, channel events, and meta events
- Visualize notes, velocities, channels, tempo changes, meters, and markers
- Convert ticks to musical positions and elapsed time
- Play through the system synth and export event CSV or a normalized SMF copy
- Complete bundled sample and local comparison workflow
- Local PDF report and Apple system share export
- Original offline technical reference library

ONE-TIME AND PRIVATE
- One paid download; no subscription or in-app purchase
- No account, advertising, analytics, tracking, or developer-operated backend
- Core features and bundled content work offline
- Work remains on device unless you deliberately share or export it through an Apple system interface

Midiary preserves imported files and does not claim identical sound across synthesizers. Verify SysEx requirements, device-specific controllers, and rights to any composition before export.
