My old roommate has a guitar with the TransTrem modification. Not only will it autotune to standard guitar tuning (eadgbe) but it will also drop each string 4 whole steps & raise each string 3 whole steps. Any other combination is available as long as it fits within these parameters. He can store up to 99 different tunings & recall them either with the buttons on the guitar or with his feet via MIDI. The system has servo-motors on the bridge end & a locking nut on the tuning peg end. The tension of a guitar string is very small in comparison to a piano string not to mention 3 strings. If it could be added to a piano you could have just about any tuning you want within the range a human tuner can achieve. If the piano went out on tune during a concert, it could be retuned while the pianist is playing by someone off stage. The termination of both ends would probably be much better because both ends would be clamped to large metal pieces at each end. Speaking of poor termination... maybe Yamaha can put one in their 333,000 piano........... Not only is there the cost of buying the unit but also the cost of installing it & making the modifications to the piano. Since no one seems to agree on which way to make a piano, each one would have to be custom made.........$$$$$$$ Thats my 2 cents +/- ra byn james - 28
