a way to masterdimm several effects at once

heres the thing:

for a bday party in 4 weeks im planning sound and light.

since light is my main specialty, i will invest the most time and equipment in light.

im using different effects from movingheads, rgb-strobes, led-bars, flar pars, martin rush wizard, hazer fogger lasers and so on. for this event i was thinking about a way, not to blackout all effects BANG darkness (which is pretty convenient), but to slowly (1-3secs) dimm all running effects down to 0/darkness, and have them continue at 100% when the bass kicks in.

until now, i either have a scene or chaser running, or i controll the effects nsync manually with the music. as i was thinking, i couldnt think of a way to masterdimm all effects at once, bcuz every effect has its masterdimmer on a different channel. on my controller (glp Scan Operator FX 2) i can remap single channels (i think?), so in the end i could setup this thing to have every masterdimmer for every effect on one channel, but this will lead into chaos and confusion, since im using a print-manual with all dmx-functions while operating the controller, remembering every function of every channel of every effect is almost impossible when sober, when drunk, no way no chance. im looking for a solution as simple as possible, bcuz, as said, ill be drunk

another way could be, to have several scenes with stepped down dimmer like 100 80 60 40 20 off, put this into a bank or chaser and let it run at a defined speed. 

problem is that chasers/banks on my controller loop, so dimmer wont stay off. i have a freeze-option that stops every dmx-output until release. hmm.... dmx is complicated stuff and lighting dudes dont get the attention they deserve. still.

if someone has an idea, im all ears.  greetings

hi, im not that smart. could you explain that step chase dim fade thing?

i almost never work with the override scenes except blackout. when drunk, strobes hammering and its time for full on, when sensible chicks complain, i cant help, me and the boys have always fun :D 

i try to setup everything while sober.

ill check out that wolfcontroller, looks weird. never heard aboout s.t. like that. looks similar to that korg-pad for different dj-effects (which is not my field)

avolites looks like some serious stuff for professionals which im not even remotely.

im glad that i can operate that small fx-generator. when i see those cracks with these huge controllers on some events, i always think, that im nothing compared to these guys running 40 50 60 MHs and countless other effects or programm this stuff beforehand.

i think i will play around with these fadetime-functions, which i think, i dont even understand completely :D but this looks like s.t. i could use.
