Check out my inventory:
Studio42 Gear ListBased around a 76-input A&H ML5000 48B. Loads of goodies external(it has to be, it's analog!)
Even when and if I ever get well, I'll still be on here. Ever since the big beat-down on my February 27th show, it just wore me out like nothing has in a long time, and that allowed all this other crap to creep in and kick my butt on a microscopic level.
Now, your cans are wash lights, but I understand your application. They should work fine for what you are planning to use them for.
Also, I can't relate the DMX values to reality, but if your eyes like what you see, then that's really all that matters. I can somewhat agree that the pure white from the LED's can be a bit "cold".
Also, I'm real bad on the visualization stuff too. Not to plug MyDMX, but you can quite literally make a picture of your stage and your fixtures and your gear(including band members) and place them in there and literally SEE if your design works.
You're asking about the best way to light up the singers. Well, honestly, I think your cans on the trees is your best bet, and if I was doin it, that's what I would do with my own gear. The only issue is that those LED cans need some throw to work their best and avoid the RGB shadowing that is something that happens when you're using different LED's for RGB color mixing. That and beam size. Try to hit everyone from at least 2 angles. You may wish to consider a footlight application as well. I see the Profile Panels and the Mega Bar 50's being pretty good choices based on cost and size and how their beams tend to stay right where you want them.
Not to knock Chauvet, but have you thought about the ADJ Mega Pixel or a newer similar type fixture for your back color light action for behind the band? I think because of the limitations of the Mega Bar Pros AND your controller, you'd need something else you can throw into a better sound active mode. Check your manuals, you may have a sound active mode on those Mega Bar Pros as well. What I'm really getting at is you're really not able to tap into all the cool stuff you've got in your possession right now.
I'm not sure if Jingles and I agree or disagree on this, but going back to the Aggressor Tri LED, I really don't think they'll take more than half a second to come live as they aren't an intel-capable fixture. Regardless, once you get them, you can start screwing around with them and get real answers. Based on what I've learned about what Jingles has done at some of those trade shows, I can't expect him to remember such details about every fixture. If I had one myself, I'd have powered it up for you and given you an answer based on what numbers I could come up with based on observation and a stopwatch!
Well, it might be hard to justify the costs is about all I can say. Your going almost entirely LED, once you move past that Magic 260 and the color changing abilities, say, with MyDMX, you're going ot probably just drive yourself nuts with all the options you'll have for your lighting show.
With everything else you've shared, I think at this point, it's mainly see if you can try it at rehearsal this weekend in a room if space permits, just to get an idea. Other than that, your biggest issues after you set it up is to "focus", which means to aim your lights. This will vary from show to show. As long as you guys mostly stay put, you'll be fine.
On a final note:
Bore from my sick bed? Hardly. My wife decided after 2 weeks I was "well enough" so I've been worked like a slave since then. Even those 2 weeks, I was run fairly ragged. There's no rest around here.
Even my 2 weeks of what little rest I was allowed was not restful. I got my 2 pug dogs fighting for the "best position" on me or my lap as I tried to rest.(depends how it goes if I'm laying on the sofa or sitting). Plus, our(wife and I) 3 young kids that I have to watch, which is an everyday thing anyways. Nothing better than every 3 minutes someone inventing a reason to create conflict!
My task today is to unbury 2 subwoofers from the garage to use at an event tomorrow for my eldest kid's kindergarten performance. I'm running 4 camera angles, 4 mics covering zones and 2 wireless mics for the performance, plus I'm going to have 2 more wireless(one for teachers and one as an emergency mic), plus run mains, monitors and recording off my dinky Yamaha ProMix01, although I may go with my Mackie 1604 VLZ, I haven't decided yet. Also running the antennas for wireless.
Camera angles will be a wide shot, then a center close 3/4 shot. Other two angles will be an audience reaction and maybe some other strange angle just for the heck of it.
Lights will be 4 Mega Panels and 4 Mega Bar 50's in floor mounted positions, run via MyDMX. I'm not using my 8 ADJ 64 LED Pros because one is being repaired and I don't think I have the space to run the trees.
I just hope it all fits into the car on one trip!! I wish my truck was back, just so I don't have to worry about space and transport problems.
