Yes - to me and my playing technique, it seems a little more tame on the p & mp range and easier to get to f & ff without having to overthink it...it does not work for all models though...some of the warmer ones like the Bluthner and Grotrian for example...

You never mentioned what DP this is for. Velocity curves will vary by DP. For example, imagine a DP which cannot generate a 127 at all.

BTW, just for reference in this thread, this is the Pianoteq velocity curve for an NV10 created by computerpro3.

He mentioned it's for a SL88 Grand, which is a Studiologic (Fatar brand).

Someone is paying attention...

who also use the SL88 Grand.

You left that bit out, J. Can perhaps forgive Sloth for not noticing, and thinking you may not be aware PTQ curves are DP specific.

I'm not sure if someone mentioned it here, but minimizing Pianoteq window significantly improves performance on slow laptop.

I seriously doubt that minimizing PT would improve its performance as the amount of graphics processing is neglible when compared to the remaining processing. Moreover, this could be tested

I also didn't believe when I read it, but then I tested it. Max poliphony I can reach without having artifacts when PTQ minimized is so different when maximised.

I've seen this claim more than once as well. Enough where it's definitely worth trying if you're getting dropouts/clips.

When I have a lot of stuff running on my MacBook Pro (programming tools, Chrome with a lot of tabs, iTunes), minimizing Pianoteq window or putting another app window on top makes the sound stutter badly.
When I put Pianoteq window back to the frontmost, it works fine.
It seems like when straining for resources, the OS gives the priority to the app whose window is visible.

Interesting. This is the opposite of what AlphaBravoCharlie is saying. He says when minimized, it performs better. You are saying, when the window is in front (not minimized) it performs better.

Operating systems slightly prioritize foreground applications over the background applications if not configured otherwise. Minimizing a window may increase the performance of a graphically intensive application (for example, an application writing a large amount of text to a command line window will run faster if the window is minimized). So, putting a web browser with a dozen of tabs as the foreground application is not a good idea, especially since some of the the pages are likely to be running extremely inefficient and resource intensive scripts.

Anyway, Pianoteq is not a demanding application. On my system, it averages 5-6% CPU usage, of which ca. 3% are from the ASIO driver. If I use Pianoteq with 256 polyphony to render a high-definition MIDI recording of a demanding piece from the Piano e-competition, it may generate a couple of spikes to 10-15% CPU usage. So, unless the system features an old low-end CPU, any sound dropouts in Pianoteq are mostly a consequence of the system configuration and/or other applications, not of Pianoteq itself.

Oh. Sorry.

Usually, real time music software (DAW), use a special priority scheduling : MCSS (https://docs.microsoft.com/en-us/windows/desktop/procthread/multimedia-class-scheduler-service), then it has a high priority for 80% of the time. Putting the application on background shouldn’t hurt the CPU allocation.

However, with important samples, I have to keep the application foreground since the memory allocation tries to page out background application first when the free memory is too low.

In another thread recently it was suggested I show my Pianoteq velocity curves. These curves are always works in progress, but at present I'm reasonably happy with two of my Bechstein DG curves.

My main issue with all Pianoteq instruments is that the sound is dominated by the strings, and it sounds very metallic. In a real grand the sound is dominated by the soundboard, and it sounds woody. Since Pianoteq sounds are most metallic at the largest MIDI values, I generally design my velocity curves to avoid a good part of the highest MIDI values. This way I really have to hit the keys hard to hear the metallic sound.

Implicitly this procedure reduces the dynamical range, so to compensate I raise the dynamics slider to somewhere around 45db to 50db.

Of course the velocity curves also must depend on the digital piano, or keyboard used. In my case this is the Roland FP30.

The two Bechstein DG curves that I currently prefer are:

Velocity = [0, 17, 36, 54, 76, 101, 127; 0, 17, 38, 67, 91, 107, 116]

and

Velocity = [0, 20, 51, 89, 127; 20, 34, 65, 90, 102]

The latter being the more extreme one, but of the two I prefer the former.

Both can be pasted into the VELOCITY graph (just copy and paste the whole line as shown).

Thank you for this! I will be trying both of these out!

Well done Quasi, and thanks. I'll try those at my earliest convenience, look forward to it.
Re your earlier comment about the auto velocity calibrate function--mine didn't deliver a useable result, either.

If your trials precede mine, Sloth (probably will)--maybe you can report on here later.

Harrumph, here's a tip--for me. Been trying to enter Quasi's curve in PTQ...wouldn't paste. Stiĺl don't know what the second set of numbers is for (after the semi-colon), so couldn't enter it properly with the line dots. Apparently--according to a thread by DavidB on PTQ forum...you have to copy (and paste) the whole line, including the "velocity=" and the square brackets. I was just trying to paste the numbers on the velocity panel. Tut. Will try that tomorrow.

EDIT--Quasi said it--

You should meet the acoustic grand at my school.
That thing sounds harsh and metallic no matter what I do. Even my teacher admitted that it is hard to make it sound soft and warm.

I feel like a construction worker trying to pet a fluffy kitten when I play it. All I can think of is "be more gentle" yet my hands rarely comply.

Compared to that it's a cakewalk to make pianoteq sound soft and that is with the standard linear curve. So I guess it heavily varies even among acoustics.

Very true, not many appreciate that. And Ptq demonstrates a similar tendency with it's range of pianos. Try the old bechstein.
