Sync points — paste / edit manually (or use “Load Sync” above)
Soundslice format, exported via More → Export syncpoints. The Load Sync (.json) button up top loads it directly.
Paste Soundslice-style syncpoints. Each = [bar, seconds] (bar is 0-based), optional 3rd value 0–480 = position within the bar (240 = halfway). When set, this overrides BPM and the lights track the recording exactly — handles rubato. Clear the box to go back to constant BPM.
Upload a tab MusicXML (export from Guitar Pro / MuseScore as .xml / .musicxml) — notes light up on the board. Add an audio file to play along. For steady tempo, tune BPM + Offset. For expressive playing, use sync points above. (Video export — next step.)
