Turns out it didn't need such a big adjustment after all. I will post an image shortly

I think it IS achievable. I must point out at this point that I set ALL unison widths at level. This enables me to hear the differences in velocities clearly without those differences being coloured by variances in unison width.
The .mp3 (Acuna88 levelling 1) uses uniform unison width.

What do think? I think my hard work will pay off eventually!

Actually, listening through my iPod, it seems it needs a tweak in the forte range!
Will I tweak forever???

If the Pianoteq internal algorithms do not mimic the effects achieved by those who voice real pianos by hammer adjustments then you very well might. What do you think so far?

In the above .mp3, two notes are repeated. They are the matching pair C# and D (next to middle C) where D was adjusted to match the C#.

I'm getting the hang of it I think. I sure hope to speed up - this one took quite a while!

here is an illustration of a single adjusted note

.mp3 demo to follow in a few minutes

It surprises me that you need little adjustment to the pp-p range. If there was a friction variation, I would expect this to affect low velocity more than high. Or maybe there's just a fixed percentage error? Do you find that for a single key, the adjustment is roughly proportional to the velocity? I guess that will be clear in your numbers.

To be honest, Fatar/Studiologic have actually done a very good job in improving their velocity response so I am not dealing with a sluggish action in the Acuna88. You are right about friction and it's effect on the ppp-p range. Whilst working with the NUMA Nero, I DID have to work on this range more, simply because it was more irregular.

I have been working on the Acuna again today and have begun to realise that there is an art to toning. The thing is, the aligning of the velocities requires one to listen very, very intently. The levelling usually requires the adjustment of all thee zones (piano/mezzo/forte) to produce the desired conformity. I'm going to do some more work tonight and will update tomorrow.

Thanks Sigasa and all, I hope to improve Pteq by asking good questions.

I still say that the dynamics slider (per note edit) would be a valuable tool
in our quest to get these keyboards perfectly evened -out, velocity-wise.

I don't have much faith in my ability to accurately control velocity in my playing and I've been wondering if I can do something more reliable. What do the sampling people use? I thought about playing pairs of notes at the same time with two fingers held tightly together. I don't think that would really reveal the subtleties you're seeing such as the friction variation, as it's comparing the results of "same velocity" rather than "same force".

Yes, I've tried using volume note-for-note. What would be a brilliant addition to PianoTEQ PRO would be a note-for-note velocity curve as many, including yourself, have suggested. But what would be even better than this would be a note-for-note velocity curve WITH SLIDERS!

I'm going to have to work a bit more on the levelling before I can contribute further. I had hoped to be able to put some screen shots together etc., but I'm still not happy with my present results. It IS my current pastime so I will keep you guys posted regularly.

If anybody who has experience with 'toning' would like to contribute, feel free.
I tuned, but didn't tone, back in the day!

The VMK188 does have some slight variations in velocity, mostly from black keys to
white.

So far I have not used the Hammer Hardness to offset these discrepencies, per se. What I have
used is a midi filter application  in host "Cantabile Performer" . this midi app is called
"Pitch Based velocity Ramp". With that app, you can adjust each keys' velocity offset
(before Pianoteq)individually. It's NOT a separate velocity curve per key, but is the best
thing I've found (so far) to even out this keyboard. (sorry if that solution is outside of
Modartt). I might try Sigasa's  Hammer Hardness method thing further.

Q for Sigasa, do you also use the volume per note edit along with the Hammer Hardness? My
perception is that the Hammer Hardness deals more with brightness than volume inequities.

One lingering question I have would be; Why does the  "Dynamics" slider not have a per note edit
in Pteq Pro?? I would like to know the official answer to that. It's kind-of  puzzling!

Also one big request for Modartt would be to make the "Velocity Curve" a per note edit in
Pteq Pro.  (hint, hint!!).

Anyway, I love Pianoteq Pro Bluthner, and I am interested in  your guy's ideas about how to
make it work better.

The simplest answer to you question "where do velocity errors come from" is that
they most commonly come from physical irregularities in keybed regulation. For example, if I apply exactly the same down force when playing two consecutive notes, and the second key has more inherent friction in it's downward travel, this second note is going to produce a 'quieter' sound i.e. a difference in velocity response.

I must admit as some of you already know, I've been messing with this velocity stuff for a few years now and an still learning! I guess I AM a little more fussy now as I can hear irregularities very clearly after so much practice. I've been working this morning on perfecting the Acuna88 response and still have work to do to achieve this, but I will say this, that there will probably be very little adjustment to the 'piano/pianissimo' range. Most of the adjustments will commonly be in the 'mezzo' range. I will work some more and, as indicated last night, attempt PART 2 of the 'tutorial' tonight.

As you request mooks, I will send some illustrations showing screen shots of corrected velocities and yes, there do tend to be patterns. If the keybed is twisted, there will be undulations and peaks and troughs etc. in the corrections.

More soon,

Kindest Regards,

Chris
