Del Vento Let me know a bit more about it (e.g. repeated how fastly? what dynamics? what PT preset if relevant? etc)
I tried to find in my hard drive the Reaper project that I ended up doing, juat to test this in a more exact way, but could not find the file. But it is probably not important…
This is probably a case of high expectations that were defrauded. Coming from classical guitar I am extremely sensitive to repeated notes that sound as copy of each other. In guitar, if you have to play the same note three times in a row (not necessarily fast… it can be a low repetition) you vary slightly your attack, or move the finger in relation to the fret, or decrease a bit the tension of your finger in the string, so that there is a small but elegant timbre variation that is very musical. This is one of my main technical problems, because as a beginner my succession if 3 notes sound like ploink ploink ploink, all the same exact ploink… And if a listen to a good pianist, there is an elegance in the way the ploinks are linked, that I cannot mimic.
On an acoustic my ploinks are also not much better, unfortunately. But I thought that part of the problem was with the VST sampling: after all it is a recording of a ploink, and their replay should sound the same. Hence my interest in pianoteq, because it was not a recording and therefore it would be more "organic". And it was even worse than with garritan cfx. The sounds were so sterile and so mathematically correct, that they were even more copycat. Thus, my assumption (not tested, speculative, and eventually false) that the equations of pianoteq are very simplified and that get rid of the important non-linearities of dynamic systems (DelVento: you certainly understand what I am talking about in the realm of realtime modelling of complex nonlinear systems).
Then I did a simple midi file with repeated notes of various durations, same and variable velocities, etc. And the resukt was the same: pianoteq sounded like sample playback, and for some reason, it was more robotic than VSTs. My guess is that the slight variability in garritan is caused by the scripting: each note is in fact a combination of several samples, so the smae note at velocity 70 or 75 sounds a bit different, while pianoteq at 70 or 75 is just a boring change in volume: the sound profile and decay is the same.
