Sorry for the delay. Where do I find the compressor? (which menu)

I really love the way it sounds. The latest version works well on my unit. (as they all did)

any luck with the limiter?

Nice! :-)
much better re: clipping.

very cool. I'm having fun playing with the modulation on it.
When I use a high mix amount, (at high resonance) it occasionally clips on some patches I made with it. the prior version did not clip at the same settings.

cool video. Yeah, thats the exact sound that inspired this idea.
I look forward to what you come up with next.

thanks. Playing it now. Sounds even better with the bass. :-)

After playing for a while, I agree re: bass. I noticed that over the range of the mix parameter, I am always playing under 0.6 or so with this effect or it gets oo thin, which makes sense because it is a BPF.
Question: modulating FX2 parameter 1, modulates spread?
Maybe spread should be hard coded to max, and the parameter should be cutoff freq.

Nice. 
It sounds exactly like I had hoped. I'm going to play with it and do some sound design tomorrow. I'm really excited about this.
@toltekradiation great job as always!!

That block diagram for the Stereo Random Filter is exactly what I was thinking about implementing. Maybe the parameters should be 1) phase and 2)mix (wet/dry). I'm not sure why I remembered it as auto filter.
How would I take the current BPF code and modulate it like in this block diagram? or is it really 2 BPFs (L and R) code wise?
We could use the existing LFO and a mod matrix slot to modulate it.

I was recently playing with a Korg Triton... and one of the FX in the Triton would be great here, the "auto filter."
So, its basically 2 band pass filters where one is hard panned right and has panned left. An LFO modulates the cutoff freq of the first BPF and the same LFO but 180 out of phase modulates the second BPF. LFO waveform is the "random" waveform. resonance/Q is set relatively high (but not self oscillating).
Parameters could be:
LFO Rate
Mix (mixing filtered and unfiltered sound)
How this differs from using the current BPF and modulating that using the existing LFOs is the second BPF being modulated 180 out of phase with the first one for a nice stereo effect and the "mix" parameter. this gives a good amount of motion to pads. In the existing BPF, you can't mix the un filtered sound with the filtered sound.
Thoughts?
I would probably start with the existing BPF code.

@Xavier Exactly. Let me know if you want me to run before and after plots of the USB supply noise. I don't mind un-soldering and remeasuring.

I think it's solved.
ahh, I'm wondering if a jumper fell off those pins. looking at the build docs, those 2 right most pins should have a jumper. My PCB does not have this legend on the silkscreen.
