⚠️ Technical Limitation
- ✅ Solo voice recordings (a cappella)
- ✅ Single-instrument MIDI files
- ❌ Do not use with: orchestras, bands, polyphonic choirs, or multi-track MIDI files
Reason: This tool assumes monophonic pitch extraction.
🔧 Recommended for Physical Perforation
- mm/sec: 10–14
- mm/note: ≥2.5 mm
- Min Gap: 120–200 ms
- Hole diameter: 1.5–2.0 mm
These values help prevent holes from touching and ensure reliable perforation.
⚠️ Important
- If holes appear too close or touching, increase mm/sec or Min Gap
- This tool does NOT automatically enforce physical spacing
- Always visually verify spacing before perforation
- mm/sec: Controls horizontal spacing (time → millimeters)
- mm/note: Controls vertical spacing between notes
- Min Gap: Filters notes that are too close in time
- Export Bars: Continuous rectangles (visual reference)
- Export Holes: Individual perforation points (real use)
- Zoom: Mouse wheel
- Pan: Click + drag
