PROGRAMMING cont.
Using these
tools, you can make a number of Environments - for example:
1. Switch on the following: "S1-1" - Irises open, "S1-7" - one of each colour, "S1-8" - Pans and Tilts on central
point, "C1-2" - the Stopper Chase and "C1-1" - the Slow Gobo Chase. Save the result on Environment pad -
"E1-1".
2. "S1-1" - Irises open, "S1-2" at 55% - Colours rotating slowly, "C1-1" - Slow Gobo Chase, "S1-4" - Stoppers
open, "C1-3" - Movement Chase, Save the result on Environment pad "E1-2".
Just a few ideas to fire your imagination! Programming in this way is fast, versatile and creative. To our
knowledge, OSKA and the Masterpiece are the only controllers in the world capable of it.
The Joystick crossfades between 4 scenes on Scene Keyboard 12 - a Left, Right, Up and Down Scene - the Joy
Centre Scene is not in use at present. These Scenes need to be switched on for the Joystick to work, although
you could just use the Left and Right Scenes on their own for example.
For use with Intelligent Spotlights for moving the light beams, proceed as follows:
1. Make a Left Scene which just contains the Pan information for the left limit of movement. You can use the
Tilt as well to find the positions but remove the Tilt levels just before Saving Output To Scene on 12.13.
2. Make a Right Scene which just contains the Pan information for the right limit of movement on "12.14".
3. Make an Up Scene which just contains the Tilt information for the upper limit of movement. You can use the
Pan as well to find the positions but remove the Pan levels just before Saving Output To Scene on 12.16.
4. Make a Down Scene which just contains the Tilt information for the lower limit of movement on "12.17".
You should find that the beams move around fairly well together but a little trial and error is sometimes required to
optimise the movement. The Joystick doesn’t quite go to 0% or 100%, so you may need to make scenes slightly
beyond the limits actually required. Unfortunately, it is not possible to switch these scenes on to modify them, so
we recommend that you make the scenes on Scene Keyboard 11 for example, which
can be modified, and then
save a copy of them onto the special Scene Keyboard 12 ones.
LIMITS - to make a practical product, at a sensible price, we have been careful not to over-engineer the
Masterpiece, this means that there are a few limits on the use of memory which you shouldn’t meet in practice but
of which the programmer perhaps ought to be aware:
Areas of memory are shared for odd+even pairs of Keyboard pads. For example "S1-1"+"S1-2", "C2-3"+"C2-4",
"E3.11"+"E3.12" all share memory areas which gives the following limitations:
Scene Limits - 128 Channels with levels greater than zero (> 0) per pair.
E.G. if "S1-1" has all 108 Channels > 0, then "S1-2" will partly overwrite "S1-1" if it has more than 20 Channels >0.
Scene Chase Limits - 112 steps per pair.
E.G. if "C1-1" has 100 steps and you try to give "C1-2" more than 12 steps, a "FULL" error message will appear in
the 4 Digit Display and Program Chase Sequence will be exited. If "C1-1" is no longer needed you could delete it
- see Program Chase sequence on page 5.6.
Environment limits - 122 Channels, Scenes and Scene Chases, with levels > 0.
E.G. if "E1-1" has 100 Channels, Scenes and Scene Chases > 0, then "E1-2" will partly overwrite "E1-1" if it has
more than 22 > 0.
Solution - if you need to make a number of large Scenes, Scene Chases or Environments, store them on
alternate pads e.g. S1-1, S1-3, S1-5 etc. and use the intervening pads to store simpler ones.
