Drop in an audio file and get its key, tempo, a chord for every bar and the melody as tab. Pick guitar, bass or piano first and the melody comes out as guitar or bass tab or a simple piano staff. Fully on-device: no cloud, no account. Transcription is single-line: it works best on a solo, a melody or a bass line. Correct any note, fix octave jumps, then export the result and keep working on it. โ€ข Key and tempo โ€ข A chord for each bar โ€ข Melody as guitar or bass tab, or a piano staff โ€ข Opens WAV, AIFF, MP3 and M4A โ€ข Export MIDI, MusicXML, PDF or text tab For players learning a solo from a recording, teachers writing out a part, and bands working out a cover. Everyone can transcribe the first 30 seconds of a file. Pro, or SUS4 All-Access across the whole range, takes that to 3 minutes. Made in the UK by working musicians.
