    Sympathetic Resonance in Grieg's Piano Suite no 1

    We finally have the technology to make an accurate reproduction of the sympathetic resonance of the non-struck piano notes audible.

    By using the latest technology we can now re-create this very important effect that was missing in sampled piano libraries until now. The priciple behind sympathetic resonance is simple enough:
    "And all strings
    Which are touched in Love
    Must sound."

    Mechtild of Magdeburg, 8 centuries before Steinway over made it's first piano
    or (less philosophic) when a key is pressed on an acoustic piano, the strings for the keys which are already pressed vibrate sympathetically. Overtones of the struck string generate vibrations in the corresponding non-struck strings that start to "speak".

    This principle is translated in the use of samples. We use a set of resonating string samples and "activate" them with a piece of artificial intelligence that reproduces the effect very realisticly.
    For the demos we present here we used PMI Old Lady. There are 2 additional resonance components:
    - one is for the sympathetic resonance of the non-struck strings
    - one is for the body resonance of the piano.


    The resulting sound has aspects that are not found in any other sample library.

    The expected release date of this new technology is within 2 or 3 weeks.
    The details will be announced later but we wanted to show off these demos that we made while we were programming this new technolgy.

    This recording is made with the OLD LADY, one of PMI flagship grand piano libraries. The OLD LADY is a stunning reproduction of a Model 1923 Steinway & Sons D, that is regarded by pianists all over the world to be one of the finest pianos Steinway ever created. The samples use convolution technology to enhance the sustain pelal behaviour. Additionally we applied a new technology to "play" the sympathetic resonance of the non-struck strings that start resonating when other strings are struck.

    One note, these demos are rough; there are still some artifacts/dropouts audible when the host application CPU falls over from the amount of calculations perfromed in real-time. As you can imagine, we expect to avoid these problems by optimizing the process. to be continued

    Sounds like you did it. Now let's get some really great demos going. But from what I heard it's pretty authentic.

    Cheers,

    Jose
    P.S. How much?

    Wow...this is a great idea, and a huge step forward in music technology!
    Thanks Michiel for sharing this!

    Hi,
    Forget to mention that the sympathetic resonance programming is based on Xavier Bidault's excellent work. He deserves the credit for bringing this new dimension in sampled instruments.

    OK, now this starts getting interesting...

    You also mention body resonance. Does this mean that GigaPulse will be obsolete? Or will GigaPulse still be needed for pedal resonance?

    How does this piano perform with my ultimate midi test file?

    Do owners of Old Lady get an upgrade to add this function?
    What will it cost?

    Now things begin to really get interesting in piano sampling...
