Hi all,
Need a bit of help with programming a specific chase I need - this make take a bit of explaining, but hopefully it'll make sense.
So I've got four moving lights, and I want to create a chase that instantly puts the intensity to 100%, then fades back down to say 0% on each light one after another (position and other attributes are not needed). Sounds simple, however I need to co-ordinate when the lights snap to 100% with the BPM of a song. So on each beat, a fixture will be set to 100% then immediately after it will start to fade down to 0%, until in four beats time where it will be called back to 100%, and the cycle continues, etc..
I've tried making this as a chase within a playback, but the separate fade up / down times don't make a difference as you can only set the 'attribute fade percentages' which doesn't achieve what I want.
I have also tried to make a playback with follow / wait times by working out the amount of time between each beat. With our track (158 bpm) it happens to be 0.379 seconds. This method would work great, however you can only enter a wait time with 1 decimal place, meaning it quickly becomes out of sync with the track.
In addition, it would be nice if we could do this type of thing with the effects generator but as far as I'm aware there is no way to match the speed of that with a set BPM.
I have drawn a graph below which I hope will help to explain what I'm after - but might just end up making you all more confused, haha.
Basically, a simple version of what I'm asking here is: Is there a way to create a chase with a set BPM and assign separate fade up and fade down values to each cue within it, rather than having 'attribute fade percentages'
If anyone can help me with this, that'd be amazing! I'm next at the desk Monday evening so will try any suggestions then
Thanks
*EDIT* Been playing around in Phantom ZerOS it seems like the RampInv function in the custom effects generator gives the effect I want, but how can I match this to the BPM? Or is this not possible?
