Notation Is Harder Than Raw Note Detection
- Many systems stop at audio-to-MIDI and skip the hard step of producing readable notation.
- Sebastian says modeling musical intent and performance choices is the most difficult part of making playable sheet music.
Why The Company Is Called Klang.io
- Klang.io renamed from Melody Scanner to reflect a broader product vision.
- 'Klang' means sound in German and 'IO' denotes input/output, so the name fits their mission.
