The piezo-equipped Godin and Brian Moore guitars I have are very responsive to my playing when using either an Axon or Roland converter.
Oops, no. Not a valid comparison.
The YouRock Guitar is a game controller. If you want, the logical development after the Yamaha EZ-AG which was thought as a toy to learn music. The YouRock Guitar leans more towards gaming and tries to be more of a guitar. So far I can see it has a similar string controller as the older Yamaha device, a big difference is the electronic fretboard instead of the fret/string buttons.
Below is the EZ-AG from Yamaha, I don't know when it was released, maybe 8 years ago, approximately:
The device features a string controller (and not the first one of its breed), buttons on each fret/string position, audio out and MIDI in/out and sells for about $200.
It's only serious application is to use it as a MIDI controller. It provides 72 buttons, the string controller may give you more control, it is not very good but can add velocity information.
And if you prefer another shape, there is/was the EZ-EG, it appeared 2003:
So much to the "innovative" YouRock Guitar ...
I do not know if the touch sensitive fretboard of the YouRock guitar is much better than the buttons of the Yamaha EZ series but I can imagine that it gives a more guitar-like feeling. The buttons of the EZ guitars do not allow bending and only limited hammer-on and pull-off. No slides unless you call the click-click-click over buttons a slide.
None of those are musical instruments, they cannot replace a Piezo-Godin or a Roland magnetic pickup with well-known converters like Axon, Roland or the still very good Yamaha G-50.
Btw, Yamaha has also a MIDI trumpet, the EZ-TP:
Maybe we will see another clone, when Louis Amstrong enters the video games?
