Morning, and Merry Christmas!
I'm probably as new, or newer than you, but I've been doing a lot of research on this over the past month or so, so I'll offer to you what I've discovered.
First of all, I too, have a 32 channel LOR setup running S3. I used it and a DC-MP3 to run my show this year.
After doing a bit of research I found that using RGB lighting (using RJ's pixelnet) can be used, programmed, and controlled in LOR's S3 software. As you probably know, a PixNet universe is 4096 channels (8x512 DMX channels). To get them in your S3 software, insert 8 new DMX devices/universes (512 channels each) and convert the channels to RGB. You CAN leave up to 512 of the first DMX universe to control other DMX devices, you can also use LESS than 512 channels as DMX (128 for example) and use the rest as RGBs.
The latest firmware (upgradeable) on your LOR controllers allow it to recognize if its running as an LOR device or a DMX device, so you can use your existing LOR controllers as DMX dimmer packs to control your AC equipment.
That said, you will need, at least, the following equipment...
S3 with a professional license (so it can run DMX over E1.31)
Ethernet dongle to convert S3's computer output to pixnet
CAT5 cable for connections
A Pixnet hub (active or passive)
Smart String Controllers (SSC) for controlling your RGB pixels (one per string)
DMX dimmer packs (if you want additional to your existing 32 channels)
As for the settings on your LOR controllers, controller one will be channels 1-16 on your DMX network, controller 2 will be 17-32.
Having said all of that, this may, or may not be the best way to go for you...
Vixen handles the sequencing very well if you want to take the time to learn it.
xlights can run your show from your computer (I've read that S3 can slow down the show while running massive channels)
Nutcracker can help with your RGB animations... similar to the superstar software.
Speaking of the Superstar software, I'm not sure, but it may be specific to the Cosmic Color devices sold through LOR... which is an EXPENSIVE way to go.
Hope this makes some sense and helps you. If you have additional questions, I'll do my best to answer them with the information I have. Just drop me a PM or an email.
