basic Pearl 2008 shape creation question

I want to make a shape where the tilt on a set of 6 fixtures will bump up, then return to the default position.

would something like this work?

Code: Select all

PATTERN "BUMP"
   0    0    0    0    0    0    0    0
   0    0    0    0    0    0    0    0
   0    0    0    0    0    0    0    0
  7f   7f   7f   7f   7f   7f   7f   7f
PEND


and...

Code: Select all

SHAPE "Tilt Bump" "BUMP"
6  80   64   0   0   0   0  0
SEND



(I share this console with 3 people, and guest LD's, so I can't screw anything up... )

I don't see why not. Try it and experiment.

The only restriction with this is a maximum of 50% 'bump' on the tilt, but there is no way to avoid that if you want it to only move in one direction from an origin.

ah... then this would be better:


Code: Select all

PATTERN "WAVE"
ff80 ff80 ff80 ff80 ff80 ff80 ff80 ff80
ff80 ff80 ff80 ff80 ff80 ff80 ff80 ff80
7f   6f   5f  4f   3f   2f   1f   0f
0  ffef  ffdf  ffcf  fbf  ffaf  ff9f  ff8f
PEND

erm?

Well, assuming you now want it to fade down and you're happy with an initial snap down when you fire, then yes. If you don't want the fade then you could just use one of the existing pulse patterns.

yeah, i figured that out after i posted it, and didn't have time to delete the post....

oi... two different patterns required for moving heads, one for moving mirror....

it all depends on the pan position, eh

Code: Select all

PATTERN "WAVE DN"
   0   18   30   47   5a   6a   76   7d
  7f   7d   76   6a   5a   47   30   18
   0    0    0    0    0    0    0    0
   0    0    0    0    0    0    0    0
PEND

PATTERN "WAVE UP"
 ffe8 ffd0 ffb9 ffa6 ff96 ff8a ff83 ff80
 ff83 ff8a ff96 ffa6 ffb9 ffd0 ffe8 0
   0    0    0    0    0    0    0    0
   0    0    0    0    0    0    0    0
PEND



works nicely on the simulator, going to test it on the console Friday.

Would it not be better to program moving heads so that the pan position means tilt direction is matched? Or re-orientate the heads? Or use Invert on one of the fixture types tilt channel?

Not only will this mean only one shape is required but, more importantly, using tilt will move everything in the same direction.

the idea is for everything to move the same direction... up, then down to the original position, then rest for a couple of beats :D

Clearly. My point was that you should be able to do this by programming/patch/fixture orientation, rather than need to have two separate shapes.
