MS10 pink noise

[nuromantix]

Please move if this is in the wrong place.
I've got an MS10 and wouldn't mind selling it to make a bit of space but there's one thing on it I love: the pink noise.
Really good for claps and stuff.
I can't figure out what's going on with it, I can clearly hear it's different to the white noise but I don't know "how".
I'm sure I could rig this up on a modular and lose the MS10.
Is it some kind noise with fast sample and hold, like a random square wave?
Anybody know the details of how the MS10 generates the pink noise?

Thanks!

In general, pink noise is white noise with a 3dB/oct lowpass filter applied. I am ignorant to the specifics of the MS10's pink noise.

The MS-10's pink noise is just its white noise filtered by an active single-pole low-pass with a cutoff of a little over 1kHz. It'd be a piece of cake to do this with a modular. Or you could build the same circuit for the price of a coffee.

Making a circuit for technically correct "pink noise" is not quite as basic as that but for synth purposes, a simple soft low-pass does the job just fine. I've not seen many synths use anything more complex, except maybe the Minimoog.

That's interesting. It works really well as a modulation source.
I never thought of filtering something that I was going to use a modulation source.
I only ever thought about filtering audio.

I'll try it on the modular and see if i get a similar result.....

thanks again.

Filtered noise is great for modulation. Try using a smidgin of filtered noise to modulate delay time on a lo-fi delay, and then play with hi, band, notch and low-pass versions. Great for pseudo-tape effects.
