I have Freestyler loaded on my Laptop and the "dongle" for connecting to Laptop and DMX cable. At the moment I am using all in stand-alone mode, static color for Uplighting. But, I have used the ETL Flat Par Pros in a 4-bar configuration on a T-bar. Also, linked two T-bar of FPP in Master/slave mode. I have a 50' xlr cable that I use to connect them which puts them about 30 feet apart.
I'm planning on getting a Revo 4 at some point down the road. I have a couple of Vue I that I sometimes add to a T-bar.
Instead of purchasing the Revo 4, I got a used MBT Spinning Star which does a great job of the mirror ball affect. I modified the base of the Spinning Star so that it could be mounted on a Truss end pole like you would a speaker. Raise it 10' in the aire and let it fly...but only for short 2-3 minute bursts because of the halogen bulb...it's not LED. Unfortunately, I'm not to impressed with the results. I'm looking at modifying it so that it hangs down instead of up. It is really meant for a permanent ceiling install.
I may look at designing some kind of rig so that the platform can be attached to the ceiling runners (suspended ceiling) only. I travel with a DJ trailer, so carrying a ladder isn't a problem ("Little Ladder"). But still, when you are a single operator time is your enemy.
The real eye-catcher for me is when I switch on the Blisslight 15 above the dance floor. The Blisslight 15 projects a wavy blue cloud w/green lasers that look like stars on the ceiling above the dance floor. And when the room is dimly lighted, it looks beautiful.
As soon as I get my new Laptop, I will use the current one as backup and run Freestyler from it.
