Multiple hypotheses survive
The system carries alternate pitches and positions forward until musical context can resolve them.
TAB LAB
Music in.
Playable out.
Build a tab from the part you can hear but cannot find.
Heavy ML stays off the web runtime. A configured worker can transcribe a guitar or bass stem, then humanize, validate, and engrave. Mix separation is not ready. Create never treats the Signal Fire demo as your result.
New transcription
Stem uploads can be queued for the worker. Mix separation is not ready. The studio demo is never used as your result.
Drop an isolated guitar or bass stem
What works now: an isolated guitar or bass stem can run transcribe → humanize → validate → engrave when a worker is configured.
Prototype: separate. Mix separation is not implemented — a full mix will not become a tab.
WAV, FLAC, AIFF, M4A, or MP3.
Max capo 7.
Stem jobs call the worker in this request. Keep the tab open. Mix separation is not ready. Create never opens the studio demo as your tab.

WHAT MAKES THE ENGINE DIFFERENT
Both hands matter
Fretting, picking, muting, articulation, tempo, and recovery time shape the final path.
Corrections train the product
Expert edits become structured feedback for transcription, fingering, and confidence calibration.
