Hello. I'm discovering this thread, years later, while looking to create exactly the type of piano sound discussed here. Sadly, the links to (a) the "knock.wav" convolution file and (b) the uploaded fxp file are both dead.

Would someone here be kind enough to upload these again?

i just tried to upload the knock.wav file, but it seems that wav files aren't allowed in the shared files.  perhaps that's why it disappeared.

if you contact me on FB (Budo Saurus) i can try to figure out a way to get the file to you.

I couldn't resist trying to make an old upright (starting  from preset U4 Tall). Its not the sound what is asked for in this thread, but it is like the small old Hellas uprights I have played (Hellas piano, and Grand piano, made from 1901-2007 in Finland, now in Pearl River China). Melody, got from a friend 40 years ago. For some reason, I can not get it pasted in here, but the file is in "Other files". And, thanks very much for all useful information in this thread.

Will you be posting an fxp for this piano?

This sounds, Gilles, like what I did several months ago by constructing two 'delay' effects, calling one 'Woody' and the other one 'Iron Harp'.  I would then use both of these in the "Effects" settings, varying their contributions.

More to play with, as always....  :-)

Anyone with some more tips for this effect?

The only problem with this effect is that it includes the harp resonance of the sampled piano. I wish there was one done with an empty (no string, or damped strings) cabinet. The only way to reduce the added harp that may conflict with pianoteq's, is like you did, reduce the effect's presence.

It also replaces the single built-in pianoteq reverb (although the harp may be thought as similar to a spring reverb) but for adding a more conventional reverb effect, one has either to process through an external one inside a daw, or mix the knock.wav file with another convolution reverb file. This is what I did with the file "Large Wide Echo Hall+Knock.wav" also available at the same site. Feel free to try all sort of combinations...

So far, I have taken the Envelope down to -8.0 dB/sec, and reduced the mixer to -9.0 dB (but I keep playing).  I'm not sure if there's much help with the Resample and Pre-delay settings, and I don't quite hear as much difference with them.  Overall, much closer to the "Internal reverb" of my upright Steinway F from 1885, except that my real piano has higher frequencies that prevail with this ringing tone reverb effect in real life.

Anyone with some more tips for this effect?

Did you click on the "More..." button to hear the audio demo?

Oh, I hadn't realized, sorry. Thank you greatly. It doesn't sound quite like it (too sharp!), but I guess it IS closer. I'll have to see how close I can get after the upgrade.

Here is one possibility for imitating the sound you want, starting from preset U4 a la Monk:

I found the MIDI file but I didn't edit it (since some parts are lower in volume). I just played with the Volume Note Edit to simulate this. I also didn't try to imitate the huge reverb, just a rather dry sound. See what you think. There are so many options in Pianoteq that it is possible to bring U4 close enough to most old uprights.

I also used a special convolution file (knock.wav) available here: https://sites.google.com/site/ptqspecprof/temp

That also gives me the idea to try recording an impulse response from the cabinet of the original piano itself, once I get Standard.

The only way I was able to recreate similar sounds with Pianoteq was through speakers trapped inside a wooden box to have a soundbox similar to an upright piano.

That's what the knock.wav convolution adds: The interior sound of a large upright cabinet.
