UPDATE: I'm finding the MusicPad Pro Plus to be an even more useful device than I had previously imagined, especially for rehearsal, arranging, & memorizing songs. For whatever reason, the ability to quickly & conveniently markup the score (utilizing different color pens), erasing notes, lyrics at will, highlighting passages, adding/replacing chords/words etc, For whatever reason, I'm able to memorize even complicated tunes quicker now. Though I'll continue to utilize the MusicPad Pro at gigs for those unfamilar and/or rusty tunes which my brain could benefit from a chord or lyric reminder, I particularly appreciate having all my personally customized song arrangements in 'one device' and all at my finger tips for rehearsing and/or playing, anywhere anytime. The bottom line is that the MusicPad Pro offers a lot MORE than merely acting as a digital Music Viewer on stage. - Scott
