No it should even more simple to directly asign a starting PG Number for the positions of an Articulation Dimension. You do not need inevitably to chose the dimension controler at all.

Sorry, I cant follow you. What excactly should limit the amount of cells in a Synchron-Player Articulation dimension? You know that PG provide 127 Numbers should be enough.
But perhaps you are right, if you mean you want to configure a kind of universal Articulationswitch standard Like the Spitfire UACC. Since I confess I fear currently you can only set the beginning PG Number from which the following Cells get the next Nmubers. At least I currently do not know how to asign a certain single Articulöation in a Articulation-dimension-cell directly to a certain Number without the following Cell will get the directly following Number.

for example PG20 being Legato Regular for every instrument wether VIPRO or SP
That way I would be able to move midi events from every instrument to another and be free of keyswitching
As far as I know, you can not controle neither the X nor the Y-the Axis of the VI-Pro with PG-change values at all!
If it should really be "the same way" as in VIPro, I think you should have not that problem, since in VI Pro you can only decide to use Program change instead Keyswitches for the Matrix-Selection and if you did so it automatically beghinns counting starting with PG 1. So this is also possible in the Synchronplayer just chose in the Menu of the White Field af "Articulation" the forth Position in the Menu "Program change" and chose the 1 and the Matrix selection of your VI-Pro will react similar to the "Articulation"-Dimension in Synchron-Player.
However since you can controile in VI-Pro only the Matrixselection either with Keyswitch or Programchange but not the X- and Y-Axis of a certain Matrix in VI-Pro. I can not see any possibility to asigne a certain cell to a certain PG-Value.

That is right. the Dimension Controler could not be controled by Program change, but you can chose any of the regular 127 CC's instead.
However as I said you do not need a Dimension Controler if you want to select tha positions of a Articulation Dimension by Program change as I said chose it directly in the Menu that pops up in the White field under the Name of your Articulation-Dimension.
I hope that helps
