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

i found a video that show some example of that Triton fx :

that give me some urge to rework my version !

there is more than just bass going thru,
finally i went for a soft lowpass version of the input to be mixed with the two bandpass filters.
i think it sounds better balanced this way.

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

yes, it needs some clarifications :

in the new version attached, things go like this :

The frequency of the bp filters is (f + spread) and (f - spread) for Left and Right channels, folded around -1, 1
Spread param is now bipolar, so at value 0.5, actual spread = 0

The Spread param is not accessible from the matrix, only from the ui and midi CC
From the matrix, the frequency of the bandpass filters is reachable (= f)


Edit : lowpassed signal now go through.

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.

Cool,
yes i like it as well, it give nice textures :)

i think it may benefit letting some bass go through it,
to give a little more body, like frequencies <150 hz.

i did things like that for the flanger, chorus.

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.  8)

@toltekradiation great job as always!!

ok, here is a first version :)

it's two bp filters, done in paraphonic mode,
so there is a dry/wet parameter and two params : Spread and Reso
it can be modulated from the matrix.

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.
