Love Pianoteq with my N1X but still some notes don't sound right

It’s definitely not the headphones or speakers, it is Pianoteq’s simulation.
It was more distinct in earlier Pianoteq versions.

You can hear it with the N1X speaker system as well as Syrincs M3-220 speakers or different headphones, for the Piano I use Yamaha HPH-150B and / or AKG K420, both being very nice, very good sound but very light.

My experience with playing classical guitar with nylon strings, is that they exactly don't sound metallic (since they are nylon).

I experienced a sharp metallic overtone on some keys (esp. g2-flat), but only when tuned in A=432 Hz and when listening on the studio speakers. With the headphone, this was absent.
Somehow, this high overtone has vanished. Maybe due to changed settings. Maybe, I'm used to it. Don't know.
So I guess, that there is some interference with the equipment used, as probably was the case with me.

I'm not bothered by the tone being metallic, but rather lack of overtones in the upper bass/lower mids. I've just upgraded to pro so it will be possible to experiment with overtones in different registers. I think it would be a good idea to meet with a good piano technician that have the knowledge how to voice the hammers and what impact that has on the overtones (not just harder or softer hammers) and try to transfer that kind of thinking to Pianoteq.

A lot of sound libraries (I've used many and still hold a few) may on the surface sound more 'produced' if I can put it that way.. so 'better' is a tweak away - esp. with Pro. (to me Pianoteq is more recordable - like a real piano in studio put to tape so to speak) But defaults sound workable these days for almost anything but I pretty much am an audio tweaker - so I do make my own production decisions from Pianoteq through to a collection of VST effects in a DAW to bring any VST to a 'finished' or 'better' feel anyway. To me, these other libraries are not as usable as Pianoteq in a DAW.. they're already too produced in a certain way (therefore less editable), and as mentioned, less playability sadly makes them relics in my kit.

Without Pianoteq Pro, in Pianoteq Standard you can select from 8 overtones which affect all strings, and raise or lower each. It's also possible to balance these changes remarkably well with the Direct sound duration slider on the left and hammer hardness. Apart from all the other parameters, these are good beginnings for the items brought up I think.

You can definitely add or remove overtones from any area or note with Pro, drawn in ranges via mouse, or by entering numbers. So if you hear too much wire in some range, you can simply drag the mouse to draw 'less' overtones or sympathetic resonance of the 30 or so params. For example, in the Spectrum Profile in Note Edit mode in Piantoeq Pro, choose a filter (4 comb, 3 harmonic, major etc.) or other tools to remove or enhance some type of ringing or metal/wood.

With bass notes sounding tubby, maybe you could get some good results by moving the sliders in the action section (action button is on the front of interface in Standard and Pro) 'Damper position' and 'Damper duration' - by lessening or increasing both or either of these, you can profoundly affect the timbre of the bass.. so they may ring longer or damp quicker, and with the damper evoking more or fewer disruptive overtonal qualities. Or just cut a little bass from one of the 2 EQ tools (Pre or Post) - or lower reverb, in case you are in player position trying to emulate reality better (compared to making a 'recorded album piano' type sound).

Beyond that, you can get into the different EQ types available and zoom into some great detail - there's nothing a sound enthusiast can't do with all the controls I feel - and always love to encourage people to putter about with the settings until they make bells ring

Going further though, there's a lot of better sound to be produced from a fine edit of your velocity curve - or go through the calibration process a few times more to help make some well informed finer edits. The curve I feel is probably one of the main ways in which you can elicit the best results from Pianoteq.

Yes, I'm working as a piano teacher since around 20 years and are dealing with some top grands and uprights on daily basis. However, I think my perception of the Pianoteq sound has to do more with my lack of pianoteq-experience rather than pianoteq lacking in sound quality. I'm feeling more and more that the key to a great sound in Pianoteq is a proper velocity curve just as Qexl is pointing out.

Hahaha, ok sorry

I have to say dklein, I like your wording ‘creative purposes,’ more than one might, downright mistakes.  The presence of nonlinear velocities showing up anyhow in a posted preset (FXP) seems opened still to debate.  And, the fact whether or not one includes them rightly or wrongly inside his FXP posts, is a topic likely unto itself for some sorts of very heated but equally encouraging discussions now.

Let’s see, on one hand a body includes them, presumably, to calibrate inside your dwelling your keyboard —irregardless of its manufacture— for you, and as artistic expression solely but to dismiss your own calibrations painstakingly made by you after you got your copy of PIANOTEQ and did only as the software suggests you do  —from a copyrighted manual.  All this occurs, presumably, for you to get out of your playing the creative purpose the poster initially intended and meant for you to get, all while seated at an entirely different controller.

On another, you simply just calibrate your board to interface with each piano model, each you get  —including his!

From previous post entries you and I know you’ve had your pet peeve quite awhile now.  Personally, I’m just glad you’ve discovered VelPro from Springbeats.  Now you have a happy medium too!

It allows individual note velocity adjustments, both stuenn and johanibraaten along with sb56637 can appreciate.

Thanks for the tip. It sounds very interesting. I would like to try to alter the "velocity balance" a little bit and make the touch a little lighter in the lower registers and a little heavier in the upper registers. Is that possible to do globaly or do I have to edit note-per-note?
