It's still available. I used it not very long ago in collaboration with user teacue.

Thank you so much for the quick response and the links. I´ve just loaded it up and it looks incredible. I am so excited to try this out, I´m like Charlie just as he´s entering the chocolate factory.

UPDATE:

Fantastic work - what a useful tool - I can´t believe how well my first attempt has turned out: the results are faster and SO much better than trying to eyeball a frequency analyser and type in the results by hand. Thank you once again, I will certainly be sharing these fxps with the community in the coming weeks!

A very interesting tool you have created. To come up with such a thing - Tuner Entropy in the file saves data not only about the partial height (up to 50 in the bass notes), but also about their relative volume. Though the volume of the partial very mobile concept, yet the program has some mechanism to maintain this setting. Let us assume that there is a file created with a living instrument and file created the acoustics of the program through Pianoteq. If any application has made a difference in the composition of partial compensation, and generated a range of settings in Pianoteq. Does that make sense? Or good enough acoustics for Pianoteq and then nothing is compensated?

Not sure I fully understand your question, but here is a partial answer: the relative amplitude of partials varies continuously when the pianoteq engine outputs sound according to the myriad parameters of what is played. What I do is, for a fixed velocity of source and target instrument, calculate the amplitude difference for each partial, thus modifying the default values in the spectrum note edit. These are of course made continuously variable in the rendering, but the correction seems to work at other velocities than the ones used. Of course, it's an approximation, but there is only one possible value to be entered for each partial. The very useful note edit rescale tool can be used to fine tune the modification that is sometimes exagerated.

By the way, the pianoteq model is getting so good now that I really don't feel the need for this software anymore...

Is it possible to output fxp directly? Pro version is too expensive, but standard can load its fxp without losses.

I went ahead and did all the notes one by one I didn't see a way to change the Java memory on Mac OS, I didn't want to spend too much time trying to google it. It would've taken me two days to get Pianoteq this close by ear! I hear what you mean about the middle range and the exaggeration, I'm now going through each note and making adjustments as there's a few out of place harmonics in each note. Thank you so much, this really made my life easier!

I'm very particular about overtones in pianos, I literally resampled one of Ivory's pianos into Kontakt ... EQ'ing each note to get the balance between harmonics exactly how I want them (very painstaking work :-P) ... I'm using those tweaked samples as the target to Pianoteq's tone right. You really saved me so much time with this program

I'm on Mac OS 10.7.4 and the .jar launches fine ... when I "Read" the Pianoteq .wav I bounced, it shows up in the window just fine, but when I then tell it to read my "target" file, it seems to be stuck with a blue spinning wheel (for at least ten minutes now). I'll try analyzing single notes to see if that works. Has anyone been able to get this to work on Mac OS?
Edit: I've gotten single note analyzation to work, I'll be able to do all 88 manually
Thanks so much for this program!

Glad to see my software is not dead...Like you must have read, I had previously not been able to make it work on Macs because of the Java engine being out of date. On my Win XP machine loading the target file is quite fast so it must be a Java problem again. Did you increase the stack memory as suggested? Both source and target files are loaded in memory for fast access.

Doing it note by note requires great patience, I can assure you. One suggestion, do not hesitate to use the rescale function after pasting a note edit. The "correction" is sometimes exagerated but goes in the right direction. Also do not expect miracles for the middle octave, the model is very hard to modify in this area if the distance between the source and target is large.

Good luck and do not hesitate to post questions (and resulting fxp of course), I'll be glad to answer them.

Since I ran out of piano samples to try with my software, I turned to the grand piano preset of my 10 years old Yamaha P-80 keyboard which is very good in the middle and bottom range, but of course lacks in the high register due to memory limitations of the time (short loops).

This preset must be an undisclosed Yamaha grand of course and the emulation works quite well with K1 close mic as a source piano.

I uploaded the fxp produced with PtqSpecProf in the files section :
http://www.forum-pianoteq.com/uploads.p...127%29.fxp

I included two short demos, one of a fine e-piano midi file of Prokofiev's 7th sonata (the beginning) and a well known blues (the ending section).
http://www.forum-pianoteq.com/uploads.p...ofiev7.mp3
http://www.forum-pianoteq.com/uploads.p...drjohn.mp3

I also tried to produce an Apple version of my software starting from a two year old archived eclipse version supporting java 1.5 under MacOSX 1.4 but I ran into a bizarre display bug that I couldn't fix. Too bad, 99.9% of the software worked correctly at first try!

Apple's recent announcement that they would "deprecate" java in the future also got me to stop trying...It may be good news if Sun/Oracle produces an up to date version for the Mac, but I wouldn't count on it.

Oops...I just noticed a typo in the name of the java executable that is on the download site. It is named PtqSpectProf. jar instead of PtqSpecProf.jar. Extra t for typo I guess...never saw it till now.

Just corrected it. I hope it didn't stop anybody from trying it out!

One thing I could add also is the fact that pianoteq's reverb sometimes introduces or emphasizes bizarre out-of-tune effects especially in the middle range for fxp files produced with this software. This may be due to the fact that target pianos are not exactly tuned like pianoteq and the included reverb resonance seems to clash with some notes.

A workaround could be using another reverb or retuning the affected notes.

Apple offers an 1.6 version only on 64 bit machines, running OSX 10.5 or "Snow Leopard". All other platforms can freely download the latest runtime from the Sun/Oracle download site, but Mac owners can't !

Ok, well I'll see if I can run your jar-file on my MacBookPro running Windows under Parallels... just too bad I can't run it on my 'normal music machine'
thax anyway!

Yes, that would be really great!

Unfortunately, having decided some years ago that physical modelling is the future, I've never owned a decent piano sample library...

And Hartmut, thanks for your comments
