Hello!
I'm new to modular and come from hardware synths.
I want to produce a sound that i´ve been doing with my hardware synths,
here is a sample:

(it's not the drone, but the Glittery on top).
It's done with a Sample and holds LFO at fast rates (between 5 and 10 Hz) into the frequency of a self-oscillating filter.

I did this sample with either an Arturia Minibrute or Minibrute 2 and I really like how it sounds, but I want to make the modular version, so it takes less space, more parameters can be modulated and it frees the arturia.

I brought my first modular filter which is a Tip Top Forbidden Planet, and though it sounds great for filtering, I tried the Glittery sound and its too harsh. It clicks with every step. I used the Minibrute SnH LFO to modulate it, and it does not reach the sound im after. Also, a little slew maybe could solve it, but the Arturi by themselves archive it, so I think it can be done with the appropriate filter.

I was wondering if there is another technology of filter I need for this sound?
What are the filters that archive this sound?

Any input is welcomed , thanks!
