Overall a very useful piece of software for guitarists. Not just the usual single fretboard display showing chords and scales. This software has a variety of helpful functions for songwriters and guitar/bass players ranging from frequency analysis to vocal removal. It could do with more tutorials in the lessons menu, but if the author's claims are to be believed, these will soon be forthcoming. For ￡35 (around $70) you get free updates for life, not just for the next few builds. I'd like to see this software in version 2, 'coz version 1 is pretty good and the 'future developments' page of the help file sounds promising. Verdict - If you're interested get it now, free updates for life sounds good and the price might rise for future versions.
