Hello, I'm back :-)
Can't understand exactly how the Velocity vector works when there are two distinct melodic lines: I can move the single points via Drawing tool (see the attached animated gif), but the result seems unpredictable: some notes will play extremely loud, others will be almost inaudible. So far I wasn't able to separate the velocity layers.
I extracted the Velocity parameter from MIDI figure, but still I can't understand the way it works.
Furthermore, why sometimes the velocity vectors cross themselves? And why I can draw three, four, five or more point on two notes only but I can't delete the single points? What those multiple points mean?

Are there 2 or more layers of velocity possible ? .. is it not one layer with multiple velocities .or make this no sense..

Example given.
In this short (*) test, I used the Dithered interpolation algorhythm. As it can be seen from the attached screenshot, I set three velocity values at three different levels: at the beginning, in the middle and at the end of the test Figure. As far as I understand, the Interpolation option chosen (Dithered) tries to "mediate" between the intermediate values in order to achieve a more dense crescendo/diminuendo as the destination point becomes nearer. I attached a zipped .m4a file with the audio result of my test.
(*) And ugly, my apologies

If you go in Hyperedit mode (orange parameter), actually you see that any single velocity point contains the values of all the symbols (notes) corresponding to that point on the time axis. Then (with pencil tool + Cmd on a Mac) you can vertically add additional points there, and you'll end with having as many velocity points as notes in that point. With a bit of luck you can then move up and down the individual points and set the MIDI velocities. The real problem comes in when you convert the velocity (orange) values to a green parameter. At that point I still can't figure out what happens...

It seems that you can add multiple velocities to multiple symbols, but only one velocity value is assigned ( wich one?)
Probably you must make the orange parameter green for handling it like all other green parameters : putting them in containers ?
Doubleclicking on the instrumentname gives a new screen ( phrase editor ) where you can give in on a easy way textvalues for the velocity

If I remember correctly, polyphonic parameters are streamed in a round robin fashion (rotating) per position. That is, when the next symbol appears at a given position, it will consume the next velocity value from the cluster there.
Therefore, if there are exactly 2 (different) velocity values and exactly 2 note symbols at the same position, each symbol should get a different velocity.
If not, it's a bug ...

Andre,
the velocity parameter behaves differently if it is orange or green. When I edit the raw notes (orange) in HyperEdit, it behaves correctly, although it takes hard times to drag polyphonic points.
But if I "Extract from Figure" the velocities and try editing them, it becomes a nightmare.
If you wish, you can take a look to the attached files.
Thank you,
Roberto
