If you have time you can post a feedback or any ideas for future work.
Thanks~

I get some reasonable rain sounds out of it for low resonances.

How did you decide on 1 + ( 0.03 F) as the amp scale for [vcf~] ?

I decide it by testing & hearing..
I wanted to make the amplitude to be stable while changing the resonance.

It's a good fit, your ears serve you well.

I tried to do this for [vcf~] and [bp~] using a VU to flatten F and Q visually. I ended up with something quite unweildy , 0.1 + sqrt($f1 * 0.6) for Q and log (sqrt(5 - ($f1*$f1*1.1e-07)))) for F, but
1 + $f1 * 0.03 works just as well I think. Shows it's better to trust your ears because a flat VU isn't the same as equal loudness.

Nice one..

In pdlab-sonicGrains-0.5
there are a lot of graphical bangs (gui bangs) that in case of low
envelopes durations (few ms) will create some clipping.
I'd replace them with [bang( messages in order not to
overload the gui. The same for the graphical toggles,
I'd replace them with an ad-hoc abstraction.

BTW, Filtered white noise was one of my first attempts to create
something interesting in PD (OuterSpace) last year..
