zebra3 lots of noise and randomness

[glittle]

One thing I'd love to see in zebra3 (or some vst synth anyway) is a full healthy compliment of noise and randomness of varying, tailorable flavors to use for modulation.

Random "streams" (one way to think of them would be sampled-and-held noise) of values, where the rate could be controlled all the way up to audio rate if possible. Also, it would be great if that stream of randomness could be smoothed to adjustable degrees.

Beyond that, ways of tailoring the actual set of values would be super helpful. For instance, if the random values were between 0 and 1, I'd like to be able to select, say, a gaussian probability distribution with adjustable center point, and maybe also adjustable width.

For example, say that the random stream was used to control pan, where 0 is full left, and 1 is full right. With a gaussian distribution centered at 0.5, you could have "most" of the panning be near center, with occasional outliers. Or, if you set the center point to be 0 (which wrapped to 1), the graph would look like an inverse gaussian, and the panning values would be mostly left or right, with a lower probability of values in the middle.

Some sort of "random walk" type of random (not really random, but...) would be useful. I'm sure there are other kinds of randomness that would be really fun to play with.

Also great would be several of these per voice so we could have additive random modulations occurring in different amounts at different rates or smoothness properties or distributions for instance.

Urs, is this something you've already thought about for Z3? If not, I can say that I am always frustrated by wanting to tailor noise and randomness more than I am generally able to and it would be really neat to have a ton of noise and randomness available for rich programming.

Zebra 2's LFO Random Hold and Random Glide is per-voice, and there are four of them. At sync 0.1 and rate 200 the LFO is running at 80 Hz. Audio rate would be fantastic, and I would fully expect it to melt my CPU.

I like the random distribution idea. It would be great to see a similar thing in Oscillator detune spread distribution, in addition to linear, exponential, and inverse exponential modes.

Ah, yes, that's a good start. Would love to see the ability to get a little higher rate, but most importantly, more than four. They get used up quickly! Hopefully being able to use different random distributions will be possible as well, that would make a big difference in the "flavors" of randomness.

You also have 4 modmappers which can make randomness

[pdxindy]

but if you want an endless amount of different noises at audio rate... Bazille is your friend!!

Have you fully explored the spectral effects with the oscillator's Resolution turned up?

[glittle]

Howard, if you're talking about what I think you are ("fractalize" etc?), then yes... that's partly how I got here actually... I wanted to modulate those with some randomness.

[spunkmuffin]

Use the ModMapper modules to modulate things. Default they are 256 random values I think. Set the ModMapper to MapQuantise and the ModMapper Modulator to an LFO. Turn up the LFO rate. You will get cycling random values...well maybe not totally random but close.
You can also then modulate the LFO rate with say an envelope for some pulsating randomness.

If I wanted random noise insanity I would preferably go straight to Bazille like pdxindy suggested.

I had the same ideas like in the original post a few years ago when I watched a lot of Daniel Shiffman's Processing tutorials, where he also talks a lot about different kinds of randomness.
Ever since then I'm a total fanboy of different forms of random streams.
I'd absolutely love it if this kind of stuff could be incorporated into Zebra3.

… and don't forget that the LFOs and MSEGs are great as sources of waver/warble! I'm working on a patch set inspired by the Mellotron (and other 70s prog instruments) right now...

What I'd like to see is a modular modulation system that consists of simple building blocks like function generators (basically LFOs and envelopes), sample & hold, slew limiters, logic gates...
A lot could be done with that that would otherwise be hard to implement.

In the meantime I'd already be happy if Zebra had the "random" modulation source from the other U-He synths
I know there are ways around that using random LFOs and stuff, but I usually need those for something else.

I missed this post the first time. Hope this is coming along well. Assuming this one be up for sale on the U-he site?

ZEBRATRON is finished. "Just" needs a bit of polishing and a couple of good demos.

[zvenx]

and to hopefully just temporarily hijack.
What became of the funk bank for Repro?
thanks
