Topic: silent sound

Hi,

I have just bought and started to use Pianoteq 3.0.3 and I love it!
I have owned a Yamaha digital piano for years and it served it's purpose. But I have always missed the sympathic resonances of a real piano.

The very first thing I tried when I had installed and connected Pianoteq was:
Pressing down very slowly a chord on the keyboard with my left hand, and then playing some ff staccato notes with the right hand. And yes! for the first time I could hear the resonances of the harmonics of the left hand chord when playing notes with right hand. I never had this exciting experience with a digital instrument before !

But: On a real piano, when I press down a chord or note very slowly it is possible to do this without the hammers hitting the string, thus giving no sound at all. After that, when playing notes with the right hand I will ONLY hear the resonances. In fact I know some real life examples of 20th century compositions that make use of this effect.

In Pianoteq this can easily be realised by changing the velocity curve.
To give the same behaviour as a real acoustic piano the lowest MIDI velocity values should give NO sound. The first MIDI velocity value where the hammer starts hitting the string should be carefully chosen. ( Maybe members of this forum can give their opinion about the ideal start value using different kinds of masterkeyboards ?)

I thinks the default factory presets for the pianos should behave as much as possible as the original instruments. So my suggestion is that the default velocity curve should be that a velocity value of 0 or 1, and maybe more, should give NO sound. That is how a REAL piano behaves. And if you don't like it that, you can change it.

I'm interested to hear your comments

Re: silent sound

Martin:

I have noticed the same thing on my Roland when setting the Sympathetic Resonance - no matter how hard I try to not sound a note, there is still some velocity which Pianoteq interprets as the hammer having struck the strings.  But this would surely vary from keyboard to keyboard.

Using your proposed solution, the cutoff point could be adjusted to suit the requirements of different pieces of music.

On the matter of Sympathetic Resonance, I've experimented with a number of acoustic grands, and have concluded that the SR in Pianoteq isn't quite enough at the default position of zero.  Has anyone else found this?  A typical setting for me is 2.0 to 3.0 for SR.

Re: silent sound

I only noticed residual velocity in historic add-ons. And the historic originals were this way, with no mute velocity.

Re: silent sound

I'm lucky, cause my Ensoniq TS12 has 6 velocity settings for piano where it remains silent at low velocity.
But i think it's a good idea to implement this in Pianoteq.
Maybe we could use the unused velocity range to something else ;-)

Re: silent sound

I'm not quite sure to understand where is the problem: as Martin mentionned himself, it is easy to have silent notes: you just need to pull down the velocity curve until it touches the velocity axis, and you can have as many silent notes as you want, from velocities 0 to 50 if you want. Am I missing something?

Naah... Don't change a thing.  I'd be afraid that if an instrument came preset with zero velocity on note on, that my sequencer may not recognize it.  As is, if I skimp over a note that I intended (just barely hit it) at least it would show up in my sequence for editing the velocity after the fact.  Otherwise, the note may not register at all and I'd miss the chance to correct a potent moment of inspiration.  Savvy ?  As they say: Let's don't fix it if it ain't broken.

Re: silent sound

If I understand right, it does not sound like this is a problem exactly, but perhaps more of a preference.  I have used Pianoteq 2.x and Pianoteq 3.xx and have been impressed with its realism compared to a real piano. 

I did notice something different, though between the two versions, which is the same basic idea the original starter of this post observed.  I could hit notes in Pianoteq 2.x and hear no sound if I did this carefully enough.  In Pianoteq 3.xx, I had to make the adjustment to the velocity curve as was posted. 

I think the request is about making the default Pianoteq 3.xx slightly more realistic like a real Piano.  The reason I care about this is because when I was learning the Pathetique Sonata by Beethoven (using Pianoteq 2.x), I wanted to get the same effect Andras Schiff is able to get when he plays the Grave section.  Specifically, the first chord and others like it are hit very strongly with the damper pedal, followed by quietly hitting the same notes 2-3 times with no sound while releasing and pressing the damper pedal.  Getting this effect requires careful coordination and results in a very sudden decresendo.  Andras Schiff explains how to do this in his lecture series, which I believe someone told the Pianoteq forum about (http://music.guardian.co.uk/classical/p...67,00.html).  The web site is quite excellent and Mr. Schiff is an eloquent speaker/musician.

At any rate, I was amazed and excited with Pianoteq 2.x when I found I could get this effect (no adjustments required) and found I can do the same in Pianoteq 3.xx, as long as I adjust the velocity curve so I do not hear the notes played again, although they can be played faintly enough to be perhaps unnoticeable.  So, my preference would be to have this capability as the default setting since it is more like a real piano.  However, I am also able to set the velocity curve myself, so it is not a critical problem to me, which is why I have not brought it up.  I guess this is a question of how perfectly can/should Pianoteq emulate a real piano in its factory state.  Since it has come up by another person, I thought I would share my thoughts.

Missing something?

No, not at all.  If one wants the notes with velocities of say less than 10 to not sound, it's really quite simple.

This is one of the beauties of Pianoteq, and I think one that isn't quite fully utilized by all of us (I haven't used it).

Actually there are many features that take some time to understand - it takes patience and some effort to investigate.  Personally I haven't even touched the Velocity curve yet, but likely will in time.

What I am coming to realize is that the default settings are really quite good, and our endless fiddling with "fpx" files is likely the result of our very much variable sound systems (if you wish this can be translated to read - some of us are judging the sound on poor systems), or our non-linear keyboards.

But I digress; the fact is, Pianoteq has been developed by people that know a lot more about pianos and modeling them than virtually any of us - how many of us are piano technicians AND mathematicians?

So I suspect that when we find "somthing wrong" with Pianoteq, we might be wise to look in the mirror as the saying goes (hopefully this is understood by our ESL associates).  And hopefully no one takes offence at my comments, as none is meant.

I couldn't agree more, Glenn.  "Out-of-the-box" (or, more accurately, "installed-from-the-download"), Pianoteq 3 is an _amazing_ piece of software -- heck, it practically _transcends_ the very _concept_ of being software!  I immediately set upon the "Worn Out" C3 setting as my favourite, and as I tweak anything and everything (especially to give extra life and richness to sustained sounds), I've found that I've had to do very little work to arrive at a satisfactory (or, dare I say, outstanding) sound.  And I've had to do very little tweaking to arrive at a whole _host_ of original settings for the new vibraphone instruments (essentially, I just increase the impedance and play with the tuning).  The settings, as provided, are remarkably rock-solid;  everything else is just a matter of taste.

In fact, I'm just beginning to plumb the depths of the tuning possibilities.  WOW!!!  Everything that I had wanted to do with a piano (or, now, a vibraphone) 10 years ago is now possible.

At first, I was a little surprised that a light touch didn't produce that "zero sound," but one only needs to tweak the velocity curve (as mentioned before) to get this result.  I don't really see it as needing to be a "default" behaviour.  (Though I would like the ability to easily save velocity curves to their own dedicated menu, as well as the EQs, which would make jumping back and forth a bit more intuitive, rather than changing [or needing to save] the whole setting.  But I can live without it!  ;^)

I must clarify as this sounds rather critical:

My endless fiddling has put me through a learning curve, and has led me right back to the starting point (the default settings with very little deviation).  This is probably because I am naturally critical (engineer) and try to improve everything (I'd try to re-design the Imperial Bosendorfer if they let me).

There is still the possibility that my sound system (more likely my hearing) isn't linear or doesn't reproduce the sounds properly because  when I try out other people's "fpx" files, I can't find an improvement.

Also I have noticed that there is no universal agreement as to which concert grand has the "best" sound.  Some love the Steinway (I've read a dissertation by a music professor that essentially said it was perfect), while others much prefer a Yamaha, Bosendorfer or Fazioli.

As they say in the birthplace of Pianoteq, "vive la difference".

Re: silent sound

Reading the reactions, I think I have to explain my point in more detail.

1. My posting was not meant as a bug report. Pianoteq does allow me to do what I want to do by editing the velocity curve.

2. The MIDI specification allows 128 velocity values. This has nothing to do with the attached keyboard or with the Pianoteq software. It is simply an industry standard. Pianoteq translates each of these values to dynamics and sound. Using the editing features the user can change the velocity curve to match his/her personal preference and keyboard characteristics. So far so good.

3. A midi note-on message with a velocity of 0 should not give any sound, and it does not give any sound. In fact, in the MIDI world it has become a habit to use note-on messages with velocity=0 as a replacement for note-off messages. The end user won't notice the difference in most cases. But a real note-off message allows to detect how fast a key is released. I don't know if Pianoteq can use such messages to control for example the amount of key-release noise ?

4. Back to the original subject. A midi note-on message with velocity=1 should, in my opinion, not give any sound either when using a piano sound. Maybe some key noise, but no hammer hitting the string. The fact is that the Pianoteq piano presets that I have tried so far, do make a very soft pppp sound when they receive a MIDI velocity value of 1. I think that is not the real-life behaviour of a piano. (A harpsichord is a different story).
I will put a little demo midi file on my website so that everyone can test this. The file plays 10 single notes with velocities ranging from 1 to 10.
You will find it here:

5. There should be no discussion about point 4. I think I'm correct ;-)
What remains a matter of taste and discussion is : what about a velocity value of 2, 3, 4, or 5. When should the hammer start hitting the string ?

We should check on the forums at http://www.midi.org
but IIRC, the MIDI standard *does* regard a Note On message with a v=0 as equivalent to a Note Off, and this is how every hardware device and software program I have ever encountered has behaved.
And yes, Pianoteq does respond to Note Off Velocity
