I often dream of a Kemper guitar synth. I sort of mash lots of features together in my brain and pretend the dream product would use them all. Like a Fishman style wireless setup. Perhaps eventual KPA/Remote control of the whole thing so all you would have to do is add a divided pickup with rechargeable battery under your strings, no other controls on the face of the guitar. Have your "synth rigs" loaded, dream product running into alternate inputs on the KPA. Instantly switch from guitar to synth or vice versa, or morph one to the other.
I quite like the idea of the Triple Play or Midi Guitar even, with near instantaneous tracking. I've used a GR-33 that was destroyed by a drunk patron "sitting down too fast" and replaced with the GR-55. This was pre-Kemper in my life. I would be VERY intrigued by any guitar synth venture undertaken by Mr. Kemper.
