On further investigation.

Parker guitars are soon to feature Auto-Tune

I thought the Peavey/Antares guitar seemed a little higher tech than what it actually is. Firstly, I got it wrong big time when I suggested the D2A's and the A2D's would need to be pretty happening. Having a look on the Antares web site and watching some videos I see there are no A2D's or D2A's. The guitar in fact has piezo bridge saddles as used by Line6 in their Variax. With the little Peavey had to say about the Antares system I was thinking (incorrectly) that there was analog to digital and back to analog circuitry utilizing the magnetic pickups where in fact it is using pickup modeling. This would seem somewhat disguised in their literature and on the guitar itself with just a simple pull-up pot to switch between passive (the mag pickups) and the auto tune (piezo modeling) system. The "m" word is never mentioned. Having said that and knowing now that the basis of the tech is instrument modeling, the auto-tuning side of things 'seems' to be pretty cool. If you think of it as having six auto-tunes, one for each string and able to pull each and every note into tune on the fly then that could only be a good thing for getting around the idiosyncrasies of the fretboard. The demo vids on the Antares web site show a guy using a Strat with a Roland-style hex pickup but I suppose as long as the six strings are separated into individual signals, piezo or hex, it doesn't really matter. Also Antares do show it's modelling capabilities so maybe this is available through midi and software?
Also if you're wondering about the green Parker Fly guitar, Parker are also partnering Antares and will soon have some form of the Antares auto-tune guitar system in one of their MaxxFly guitars. Read all about the Antares Auto-Tune For Guitar here !!
