Topic: I liked your GuitarStudio app so much that...

Two years ago I wanted to have a gadget that could do exactly what GuitarStudio does. So I started building, it was based on a Yamaha midi guitar, I added memory buttons (for the chord tabs) and just by pressing them I could change the pitch of the notes so I would get different chords.  Today I'm proud to show you the new prototype; tabstrummer.com
I still love GuitarStudio app and I love playing chord tabs. I just want you guys to tell me what you think?
