I was thinking. Instead of having to program all of my chases etc, wouldn't it be good if it did it for me, just like the F.R.O.G function from Zero 88, or the shape generator from Avolites etc.

I would like to choose which lights are part of my chases etc, say all the movers, generics stay out of it. Hit the "I'll do it for you Sir" button and watch the lights wiggle.

Any ideas??????

Yes, we have ;-)

The top two feature requests for LCedit+ v3.2 are:
1. Labels/coloring/free text for cues and layers.
2. Pattern and Paths generation.

Item 1 is a complex problem, but (2) is now not so difficult anymore, as the new cuelist editor is capable to handle chunks of DMX data very easily.

BTW I use a spreadsheet to generate the circle/elipse paths, so I got this e.g. for a medium size circle for a scanner with a p/t ratio of 1:2 (p/t channels are at 6,7, but you can paste them in any 8 bit channel pair):

The first step of a circle chase:
  show d01 for 0.10s, crossfading for 0.10s

:d01
  6[128]  7[160]

Now paste the table below into 6
6[128] 7[160]
6[145] 7[159]
6[160] 7[156]
6[173] 7[151]
6[183] 7[144]
6[190] 7[136]
6[192] 7[128]
6[190] 7[120]
6[183] 7[112]
6[173] 7[105]
6[160] 7[100]
6[145] 7[097]
6[128] 7[096]
6[111] 7[097]
6[096] 7[100]
6[083] 7[105]
6[073] 7[112]
6[066] 7[120]
6[064] 7[128]
6[066] 7[136]
6[073] 7[144]
6[083] 7[151]
6[096] 7[156]
6[111] 7[159]

If you run above chase in a layer with "up loop" mode, your scanner will repeatedly draw a circle path in 2.4sec.

So, as long as LCedit does not have a path generator, we do it ourselves quick and dirty ;-)
