The one control conspicuously absent from the CS consoles is any sort of encoder wheel. The current touch screen alternatives are just not up to the hand-to-instrument coupling encoders offer.
What would make me a wonderful Christmas present is another cell in the first Controls>Position page which could be called ‘dXY’ (delta XY) which would respond to both vertical and horizontal wiping. Wiping fully right would add 16 to the selected heads’ X parameter; fully left would subtract 16 from X; fully up would add 20 to Y and fully down would subtract 20 from it; and positions in between proportional. It would be best if the cell was central in a second row so starting with the whole screen edge to edge for wiping.
These values are chosen to cover a stage from a moving head pointing at the stage from a stage width back and having 540° pan and somewhere between 180° and 270° tilt. Pan is approximately two degrees per DMX count so the full screen-width wipe would equate to 68°. For tilt it is about one degree per DMX count so you would get about 40° movement for full vertical screen wipe, which is about right for the aspect ratio of the screen.
You would still have the existing X and Y cells to centre the head’s aim, plus any other position parameters like motor speed. The question is what should it do when you take your finger off. If you are just using it for fine control before storing the parameters then the answer is nothing. If you are using it in a live situation then you might want to pick up where you left off, so perhaps a single tap on the dXY cell would display a ‘watermark fingerprint’ where you last had your finger, so you could replace it and carry on.
