A desktop tool for converting MIDI files into Furnace Tracker pattern data. Open a MIDI, visualize it in a piano roll or live tracker view, configure export settings, and copy/export pattern data that pastes directly into Furnace’s pattern editor.
- Piano roll with zoom, pan, and marquee note selection
- Live tracker view that mirrors Furnace’s pattern grid in real-time
- Clipboard export in Furnace’s native pattern format (
org.tildearrow.furnace - Pattern Data (219)) - File export for saving pattern data to disk
- Tempo-accurate playback with square-wave synthesis
- Per-track export overrides for instrument, velocity, and spillover
- Polyphony handling — channel-per-track or automatic spillover across sub-channels
- Configurable theme with Furnace-style dark colors (editable via Settings)
- Cross-platform — runs on Linux, macOS, and Windows; pre-built binaries available
- Open a MIDI file:
File > OpenorCtrl+O - Navigate the piano roll — zoom, pan, and explore your tracks
- Switch views — use the Piano Roll, Tracker, or Preview tabs
- Configure export — adjust lines per 1/4 note, instrument, velocity, polyphony, and note-off settings in the export panel
- Copy or export — hit
Ctrl+Cor click the copy button to put pattern data on your clipboard, then paste into Furnace
