Your free online guitar tab & sheet music editor
SimpleNotation is a free browser-based editor for guitar tab and standard notation, side by side. Edit either view and the other updates. Type fast with keyboard shortcuts and a Ctrl+K command search, hear it with built-in playback (tempo, loop, swing), transpose with correct spelling, and add bends, slides, hammer-ons and more. Imports Guitar Pro, MusicXML and MIDI; exports PDF (no watermark), Guitar Pro, MIDI, MP3 and more. No account needed, unlimited scores.
Pace needs two or more snapshots. This launch has 1, so velocity and momentum read as unmeasured rather than zero.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
