Laser growing up

you can do something kind of like that with radiator. this is some pretty early experimentation i've been working on. i'm taking audio, boosting the voltage levels to +/-5 and running it into a triple bandpass filter and using the output to drive the cv inputs on radiator running a few different patches. in the first video sequence, i'm changing the LFO speed based on frequency filtered audio. that makes for some additional interesting effects. ithe video is pretty rough and it made my phone camera unhappy, but...

Very nice. Now can you detail the preset settings to modulate with an LFO instead of audio?

Please would you remind me of Charlie's last name? I keep forgetting, and I don't want to forget that. Did you ever perform Starship?

Charlie's last name is McDanald. Last I heard he had been going by Charlene, but I don't have any first-hand knowledge of that. Not even sure is she is still with us.

I am not sure if I ever performed Starship, but I don't think so.

No one ever seems to mention Dan Slater. Dan was the brains behind most of the original electronics, designed the original cycloid generator, scanner system, beam torquer, and more. He's on the original patent.

Good point. Also the Dan who produced Silk Aurora. I'd love to hear more about or be able to contact these people. Do you happen to know for sure who designed the CYGN-B digital oscillator bank?

swamidog, Great looking audio colormod effects in the video! I can imagine hitting a button to seize the audio derived parameters for the image to freeze the frame so to speak, and then modulating those parameters, and then hitting the button again to cut back to the audio colormod.

I may have used some similar effects in the attempt I made at Hyper Gamma Spaces using one projector, a Helios DAC, Lasershowgen, and some image generating tools written in java. It is an ILDA frames thing though.

video here, 2:18 for colormod effect

i can send you the presets, but you're also going to need some external modulation on the cv inputs to really drive them around.

Yes, that would be appreciated.

David Zurcher's Audiolaze unit can create effects similar to these. It accepts line-level audio and feeds it to 8 separate band-pass filters. Each band has a gain adjust (to set the "trigger" level for that band) and 3 switches for mapping the output signal to the red, green, and blue color channels. (You can map multiple bands to the same channel(s), and you can map multiple colors to a single band as well if you want.) Each output color channel has some envelope adjustments (attack, sustain, release). There's also a chopper that can be enabled for each color channel. Finally, there's a switch to control how the colors are mapped to the original ILDA signal.

It's a beautiful piece of kit. I love using it with a simple spiral raster image to create beat-synchronized paisley patterns that slowly move and shift. It works well with a Radiator, or even with just a monochrome spiral coming from Beyond, but it *really* shines when you connect it to a Z5 + console so you can use the 3 color oscillators to chop up the raster before feeding it to the Audiolaze. I never seem to get tired of the endless patterns you can create with this setup.

Unfortunately, capturing this effect on video is tricky at best. I've played around with a few different camera aps for my phone, but I haven't found one that works as well as I'd like. In person though, the results are amazing.

Sorry for the late arrival, guys. Just stumbled across this thread after being intrigued by the title.
Jumped on my rig and shot this hole flow demo, similar to what we used in Laserium i's Bolero.
I'm using RG&B sine, variable triangle and pulse width waveforms, phase shifted @ 0, 120, 240 degrees, respectively. for colormod.
The video begins with a sine QOSC @ 1024 Hz, with a sawtooth ramp @ 30 Hz.
The colormod 'spokes' are @ 2048 Hz, which crossfades to the 2nd 'hole' CM @ 30 Hz.
From there, I just start 'noodling' with off tuning both CMs to make the 'holes' flow in and out, plus rotate the CM spokes. I'm also switching between sine, triangle/sawtooth, & PWR.
Then I get into mixing in 2nd QOSC, phase shifting, opposite symmetries, etc.
All of the above is being done live on the APC40 mkii MIDI controller.
As Buffo mentioned, getting all of this to synch with video to eliminate banding was a challenge, prior to recording and the colors suck.
Hope this info helps.

Good stuff! Keep the noodles coming!!

Wow -- awesome stuff!!
