Uploaded Hamburg B sound

Very interesting work.
    May I sugest to add another mp3 file, from a sampled Steinway-B, to compare both?

Nice sound. The treble is sweet, and up close.

And you chose one of the hardest instruments to emulate. Makes me want to be able to get inside Pianoteq and be able to program each of the frequencies of each of the notes.

I do agree that a keyboard split would let you soften the bass some. (Is the timbre more crisp than that of most Steinway B's? Crisper than the two I've played years ago, but my memory may be wrong.)

As best I understand, PianoTeq will still play the sympathetic resonances, even though the notes are limited by the split. Or have you already tried it, with bad results?

In addition, the way the splits Cantabile are organized, all of the sounds of each split are passed through to the output. For the second split on each rack in Cantabile, however, you may need to turn on the Midi Passthrough button, which is just to the left of the DRY\WET\PAN sliders, with the icon of a midi connector and a down arrow.

By the way, I'm using Cantabile because I ran across it before knowing about the other vsti hosts, and because it's free\inexpensive, and because the developer seems responsive, and has interesting ideas. Other hosts may have other features. (But one that makes me want to get Cantabile Pro is it's randomization feature--you can set it up so it randomizes selected parameters of the VSTI with minimum and maximum percentages of change. May help as a way of experimenting to get a wide variety of piano sounds. I've been hesitating to buy it only because I don't want to spend time setting up a new program right now.)

Something that won't work, but that may lead us to a solution: since you're only wanting one split, with bass and treble on each side, you might try just loading another instance of PianoTeq into another Rack and PlugIn in Cantabile. (No need for another split--this would just lie beneath the splits.) You could then insert a velocity curve for it at the PlugIn level and have it just set so low that it doesn't make a sound. (Tools\Midi Filters\Add\Velocity Curve.

But then the low velocity setting would kill the sympathetic resonance, too, yes? So instead of a velocity envelope, what could be used? I can't seem to find a way to force the note not to respond to just Note on, but still respond to everything else. Still looking.

Good work
