    Show Control automation - Midi/DMX, PPT

    So, I little farther down the road, research-wise...... I realize that using a midi sequencer opens up a whole nother can of worms.... it could add some benefit for syncronized shows (dance recitals, etc), but introduces more programming and possible points of failure, difficulty in...

    starry skies

    Thanks for the replies - yeah, Arez rest easy. as I recall now it was a heavier velour or cotton backdrop - something thick enough that you could safety pin many strings of lights to the back and the wires were not seen through from the front... I don't know what it cost them or if they...

    Lighting snow

    I'm getting some snow flakes from citcfx.com - looks like great stuff! (biodegradable, realistic looking - used on many movie sets. )Great people, too. So until it arrives I did a little playing with some hole-punch dots, albeit a different creature, to get some ideas about lighting needs...

    Installs measuring room acoustics (1st reflections)

    I want to do some basic room acoustic measurementsspecifically, slapback echo in a gym (speakers mounted front of house, 13' up, 50 ft apart), bouncing off back wall 71 feet away. (room is 106' wide)Sound is good on the floor, but when you're on stage you hear the slapback too much. Setting...

    Installs Gym: Sound Absorbtion / Diffusion Panels

    Thanks for the info -I read the specs on the Owens Corning SelectSound Black Acoustinc Board and Blanket in the links Brad provided (thx) - and its pretty impressive for absorption rates. one quote I got on 4x8' 1" thick was $58- great product but also a bit out of range for this project...

    Installs Gym: Sound Absorbtion / Diffusion Panels

    Thx -Bass isn't the problem in this case - it's the midrange frequencies.We did position the speakers for the best dispersion, as mentioned, things sound great on the floor... but if you are on stage, you hear the slapbackAnd since it is a gym and there are already some 8' square sound...

    Needed: Stage Ramp (3' high) Plans/pics

    Thanks for the suggestions - I like the aluminum ramp idea - Pros: stores in a much smaller area, plenty strong. Cons: It's a nice stage, so securing it to the front without mucking it up would be a little trick. Our wooden one would set right up next to it nicely.thx, all for the...

    Design starfield projector (laser)

    Thinking of adding a starfield projector for one song in a Christmas concert. a DJ friend used one of these, I loved it. It put neat laser stars (sm moving dots) on the 50' wall behind him. We're doing a Christmas concert in a school gym and I'm curious as to how far they can throw, and...

    Needed: Stage Ramp (3' high) Plans/pics

    I'm looking to make a portable ramp to move risers and sound shells, (3-400 Lbs) etc from gym floor to stage (3 foot high stage). Not sure how long it "needs" to be for a decent angle. Rim on side to keep things from rolling off. Maybe even strong enough to move a piano up and down, (not...
