Summary: It's some difficult to play this guitars, but you can to choose between PRO Guitar and Classic Simple Guitar (5 colors buttons). I like it, but need to practice to use it all its capacity I have not use it like Midi musical instrument
Summary: Amazing! Took a little getting used to but the controller responds well to the way I play chords. I play the power chords D5, and such with my index and ring finger instead of using 3, and the controller reads it just fine. Learned a bunch of new sings for real!
