  • 1.  Yamaha transacoustic tuning?

    Posted 10-28-2022 09:14
    I'll be tuning one of these hybrid grands next month.  Anyone have experience with these? I figure there are a couple of options to blend the digital with the strings:

    1. Just tune the piano - don't sweat it, treat it like a piano duet situation... small differences are fine.
    2. Use an app  (I'm using PiaTune) and try to match the stretch to the digital
    3. Set the digital to sound and just tune the individual strings to the digital

    What are your thoughts?

    I would suggest you ask Dave Durbin at Yamaha. 
    I've cc'd him.

    I believe the Transacoustic has two samples to choose from. A medium size upright and a 9' CF grand. There may be a medium size grand in there, too, but I don't remember. In any case, don't even try to match the tunings. It can't be done and leave the acoustic piano sounding friendly. You can thank conflicting inharmonicity between the two pianos for this. Yes, it is possible to play the piano acoustically and have the sample sounding as well, but no matter how you've tuned the piano you won't like it. Using the soundboard of a 5' or 6' grand to reproduce the sample of a 9' grand is not going to allow for accurate reproduction in the first place.

    Hi guys,

    The TA2 has 7 temperament options that can be applied to two different pianos - the CFX or the Boesendorfer Imperial.  It has three tuning curves - the U1, C2, and CFX.  If you look at a chart of those three curves as supplied by Yamaha, the only real differences are at the bottom.  You should just tune the piano like any other Yamaha piano, happy that you're tuning a Yamaha 'cause they're so darned easy to tune!  Don't fight it and don't try to match the digital.

    For my part, when I'm done tuning a piano I like to play it and listen to it as if it were a musical instrument, and I am a pianist (wishful thinking, I know...).  When I couple the TA with the piano, I love it!  I know the two instruments are not perfectly in tune with one another, but they're in tune with themselves and on the same pitch, so I'm happy.
