Frequencies used by Gemmy 6 channel light show / color organ hacks / tone generation
Still considering picking up a holiday Gemmy 6 channel light show box--the one that accepts MP3 input. If I create a stereo track with Audacity or some other software, I'm hoping I could split the stereo track, sending control tones to the LEFT side (and route that into the Gemmy) and actual music to the RIGHT side (plugged into an FM transmitter).
I'm guessing a Singing Pumpkin Choir could be put together on the cheap this way. Anyone have specs for the Gemmy? Been searching and haven't found yet found a hack that describes what frequencies to use to activate each of the 6 channels. Also wondering if the gain of each tone matters and how much control you can get over the Gemmy when creating your own "control only" tones track.
I know some will say buy a Light-o-Rama. But I prefer doing effects as inexpensively as possible. Not positive I'd use it for a Singing Pumpkin Choir. But would love to sync lights with music / audio on the cheap.
Nice video of the unit playing a stock song
Found this one:
And here is an interesting discussion about the unit. Adding it here to "save for later" / for reference:
Still can't find any discussion whatever of programming your own control channel with a synthesizer. I've been looking for a good excuse to buy a virtual analog synthesizer; so this could be a good pairing. Seems bizarre to me that with all the creative Halloween folk out there, no one has already done this--or written about it online. Pretty simple concept assuming the Gemmy behaves as a real-time color organ. I get a kick out of achieving effects in the least expensive way possible so LOR is out for now. Don't really need a hardware synthesizer. I'm sure there are many soft synths or "trackers" out there that would enable be to create a control track synced to music. Hope someone beats me to it. :-)
Took the plunge and ordered the unit
Just ordered the Gemmy holiday light and sound unit from Front Gate. Hoping to use a free tracker / soft synth to figure out what frequencies its color organ responds to. Thinking also that this puppy could be used as a Pepper's Ghost fader if it also responds to volume. Somewhere on the forums I asked about the cheapest way to automate fading for either a Pepper's Ghost or some sort of scrim effect. The Gemmy may be able to serve that purpose as well. Lots of possibilities for only $50 (on sale).
Use the Gemmy for lightning change portrait gallery?
I'm thinking it might be possible to duplicate the effect in the Haunted Mansion where the portraits change in response to lightning flashes. The portraits seem to use clear fluorescent paint, turning a portrait of a lady into Medusa during flashes of what must be black light. Wouldn't work with actual tube lights due to the delay in turning on. But what about filling all 6 outlets with the largest incandescent black light bulbs one can find?
Now that I've ordered the Gemmy holiday light show and timer, I'm brainstorming all the ways it could be used for both Halloween and Christmas. *If* I can generate my own frequencies / control track and the color organ works well in real-time.
Would wrapping some sort of "purple" filter gel around a regular light also create more black light?
