Hi Bob,

I bought a Casio MIDI Guitar back in the 80s. It was the greatest. The latency wasn't that bad and was easy to get a handle on. Also MIDI Guitar has to have come a long way since then.
That old Casio was hard to set up for six string to six channel, but single note playing with all six strings on one channel was super.
I loved using a piano patch and I used to play endless piano solos.
You do have to be a very accurate picker.
Alas, it was lost in a flood here also.
I looked at a buch of youtubes of MIDI guitar players. They just seemed to like making noise. You can do some really good stuff with it.
(my personal opinion, based on old technology)
Give it a try. If it works for you, you'll have a ball.
