Here is an actual screenshot of the Guitarmaster interface:
Guitarmaster guitar software produces notated music (guitar tab in a standard .txt file) for both chord sequences and single-note melodies. It also converts them into MIDI files, which can then be exported to a standard notation package of your choice at the click of a button. No additional hardware is required except a simple connecting lead.
Unlike other wav-to-midi converters, this guitar software has been developed by guitarists, for guitarists, and is capable of transcribing everything from simple major chords through to complex altered and extended chords (e.g. Gm7b5#9). Ever wondered what that far-out chord you just played was? Guitarmaster can tell you!
