Here are a few modifications I tried: you can make a nice centered circle. Got the synch to work with bang~. Do not understand the values, found them by trial and error. Lots of fun.

Ah.. well.. in this case it's kind of weird cause i have inputs into RG and B. Try one at a time and setting the others to nothing. Imagine also that each R, G and B could have a completely different wave resulting wave form going in.
And yes... the pix objects are really fun to add as well.

Oh wow, this is really neat. I wonder how you can control the colors...Jeez I need to play with the pix_* objects more!

Hi Kyle and List,
On second thought, it might take a while for me to get back to putting this all together with the earlier patches so attached is just a simple experiment. No big deal - it takes two oscillators and puts them into RGB.
To use this:
hit destroy/create+DSP on the left.
activate the toggle (green of the left oscillator).
use the slider to adjust a frequency of some horizontal (ish) bars. (maybe around ~20) start the metro to "freeze" the image.
- turn off the oscillator and do the same with the osc on the right
but go for something like vertical bars. maybe around 16000.
- turn them both on now to see the combined result.
a circular pattern.
if you now modulate either oscillator you will get some motion but it will be more controlled.
A final video synth would have a variety of oscillators to choose from, a mixer for adjusting the amplitudes of each waveform, filters and other "pix_" operations, e.g. invert, etc. There's a ton of ways to go with this.
Best, p

Would you care to share your work with the list, in patch form?

haha... i can't be the only one who has hit "send" then figured
out
the problem.
basically i wasn't really resetting the oscillators since
sending a
number to the right inlet of the oscillator wasn't enough. once i added a metro and "banged" the input, the sync worked.
still... if there's anything that comes to mind regarding best
block~
to use, please feel free to share.
