Could take eons, like natural selection. Lotta perms possible, but enough eons to weed out to the fittest candidate, and it'll win.

I'm sorry, I meant take the latest 4 or 5 curves that have been created and blindly randomly test those.

Is it so, or my imagining?

I would suggest having a friend load velocity curves at random and let the performer pick the one he likes best.

Hi,

1. Thanks a lot for the Midi Shape shifter. It works great for velocity curves !

2. but for the design of the future vpc2 (?), maybe Kawai engineers could have a look at this...

3. But I still think the the Vpc1 is a bloody good keyboard :-)

1. You're welcome Gotacki,

2. I hope so,

3. As do I

Thanks a lot for the Midi Shape shifter. It works great for velocity curves !

About the VPC1 let off simulation, I may add that, as a piano student, I find it much useful when practising, because the real let off on grand pianos is really not my cup of tea and I had many trouble to deal with it when practising only on my upright piano at home.
As a recent owner of a Vpc1 (wich, by the way is a real great keyboard !), with its heavy touch (much heavier than my upright) and the let off simulation, i am now able to work a lot better.

Having said that, I will moderate my opinion about the let off. I think that it works not so bad for slow pianissimos (in fact, it's almost as annoying as in a real piano, haha, but that's what i'm looking for...).

On the other hand, one would notice that on a real piano action, the let off is not effective when you play lightly and quickly without pressing the key all the way (the hammer is then throwed by its inertia and the let off is not engaged). That's obviously not the case with the VPC1 let off, wich is effective all the time and then slow the hammer course.
This means that quick and light pianissimos (as in Mozart or Chopin's works) are very difficult to realize with this keyboard... So I will sure disengage the VPC1 let off as soon as my warenty will be off (in 3 years !) but for the design of the future vpc2 (?), maybe Kawai engineers could have a look at this...

But I still think the the Vpc1 is a bloody good keyboard :-)

Well I've got a worry. You can interpolate your MIDI output sure, but not the MIDI input, that's just integers 0..127. Result that seems to follow is that with some 94 input steps up to your 'mid' point (~3/4 of the input range), and 64 output steps to your 'mid' point (~1/2 the output range ....your attempt to interpolate any output can't work), what that curve produces is 1) inputs aliased such as needing 4 input steps to climb 3 output steps for the first range (zero to 'mid' point, where you'll have to hit harder than normal to make any difference); then 2) output steps aliased such as to climb four steps for every 3 input steps for the last range ('mid' point to endpoint....and you will struggle to keep output even, it'll want to lurch).

I'm tired so my numbers mightn't be utterly right, but the principle seems to be.

Hi Custral ,

I do understand your thinking entirely. Yes, there is a tendency to have to play heavier for pianissimo to mid range and lunging from mid to 127. This was something that I have had to balance in my quest to find the 'correct' middle point (node).

This evening I hit upon 83, 52 which is the best performing point I have had so far (see previous post). Please try it and let me know what your honest opinion is.

Thank you,

Kindest Regards,

Chris

Enjoy!

Hmmm...why do I get the feeling that you will eventually revert back to the original touch curve that ships with the VPC1?

Thank you James, I did wonder that myself many times!!! But something convinces me that a tripoint curve is a simple answer that is actually possible and, as you may have guessed, I have modified it since. In fact, I've made use of my VRM Box (Focusrite) utilizing the virtual ADAMS reference monitors (which sound supurb by the way) to test out this one as it sounded beautiful through my monitors ( nEAR EXPERIENCE 05's) so I wanted to check through headphones. I have recorded a demo which I shall post soon.

Here are the coordinates:

0,0; 83,52; 127,127

Also, playing the above 'curve' having previously pushed the let-off arms out of play, I am able to get great control of pianissimos. And I have great control of fortes also. I shall demonstrate this in my mp3 as alluded to.

One last thing.

The key touch feel of the RM3 GRAND II is much improved since bypass of the let-off. I do miss let-off per se, but not the spongy-ness that came with it! If I had a gripe, which I don't, I would sincerely ask KAWAI to re-look at their let-off simulation and see if they could make it less so (spongy).

P.s. James, (and interested VPC1 owners) please try out the above curve and let me know your honest opinion(s). Obviously the presence of let-off simulation for you and others will mean you won't feel what I feel in the sense of the playing experience, but do give it a go anyway if you would as I would be interested to know if 1. It performs well, and 2. It performs well with let-off simulation?

Thank you,

Kindest Regards,

The best I have managed so far is around the 90, 60 area - specifically 94, 62 i.e.,

velocity = [0, 94, 127; 0, 62, 127]

This can be used in the PianoTeq velocity pane, but I would recommend rather to use it in the VPC Editor.

I'd also be very grateful if anyone else wishes to suggest a curve for the VPC1 here in this thread. Mabry? Custral? Feline? et al

Kindest Regards,

Chris
