oscillator brightness

[lazerkind]

Or will I be pointed to DSP course 101 now?

Yes.

Oversampling (2x) means: Run things an octave lower for twice as long. Then kill the upper octave and ditch every other sample. In other words a wavetable that's 2048 samples long will appear like one that's only 1024 samples long, but the interpolator becomes better. Thus the effective maximum number of harmonics within that wavetable isn't 1024 but 512.

Take 500 harmonics at 20Hz. That means a sudden "end of harmonics" at 10kHz. So the Gibbs ringing will be beeping around at 10kHz, which is audible. It would be at inaudible 20kHz if we had 1000 harmonics.

Ok, I think I get this now.
I took a peek in the manual where it says that you use 1023 harmonics in the oscillators. And if you use the same number of harmonics when generating the oversampled sounds then the gibbs effect when downsampled will be one octave down.

I think my confusion comes from I'm mostly used to oversampling in 3d rendering and not in FFT-land.

Thanks for the lecture

Just when I thought I was starting to get a handle on Uhbik...

Along comes Zebrify.

The ModMapper starts to really show its teeth with this thing! Yikes.

Makes me wonder:

Is Zebra becoming a whole different animal?

...Or is it just starting to eat up the rest of the zoo?

Where's Zebrify?

Follow this thread back to the "top secret" link Urs dropped.

It's a little monster all right. At first I thought that Urs had dropped the FX tab (and the FX) altogether...until I found them all relocated to the grid.

They are all there....It's kinda like Uhbik squared.

I have that 'top secret' build open now. (2.3.2) But i dont see any changes at all, except for the render options in MoreOsc...certainly nothing in the FX grid mentions anything to do with Zebrify.

Oh well - it will arrive when its ready.

Zebrify is an effect plugin, it is separate from Zebra - so you won't see anything about Zebrify in Zebra.

I just wondering how people keep mentioning it, and where i can have a nosey!

btw...i bought your Zebra Science soundbank last night Howard. BIG thumbs up!! I love it. Thankyou.

I for one cant really tell the difference between the 1x oversampling...2x I guess brightens the osc, but it sounds harsh.., I probably won't use it. I actually had a feature request...now that zebrify exists can we have a feedback module for zebra (Is there already one, did I miss it?) One thing I like about massive is the switchable feedback routing ...makes for some dynamic patches. Or is this not possible with the architecture of zebra?

Speaking of Zebrify....it's amazing so far. I realize its alpha however, msegs should be given a loop mode (for use as global lfos, with a midi controllable reset switch ) instead of just triggered by midi. Its full on sonic destruction when you run drum loops through comb filters with various audio followers controlling parameters. The routing possibilities are overwhelming, between ring mods, fm by input...seriously brave new sonic territory perhaps the most insane multi fx ever? and thats before using the midi input. Thanks urs, I lost my Saturday because of this.

I'm not sure if you found it already, but zebrify is included in the zebra version linked in this thread. It's a different plugin, but it comes in the same installer, and it should have been copied to your plugins folder.

msegs should be given a loop mode

Try making the endpoint of the loop the last point of the MSEG, such that there is no other point behind the loop...

[tinkerpixel]

Oh duh....Thanks that sorts it!

[Urs]

Oh duh....Thanks that sorts it!

(wasn't quite sure myself, as some triggers and stuff are still missing in Zebrify)

Regarding circular structures / feedback... it's not really possible in Zebra's architecture. It's doable for delays that are at least 64 samples long (this is used in Filterscape to enclose the eq etc. into the delay path). This unfortunately rules out feedbacks with 1 sample delay and it's the major feature difference between Zebra's architecture and a traditional modular environment. But it's also what helps to save cpu big time

Should have been.....and infact HAS been. Thanks for pointing me in the right direction.

Thanks, I kind of figured it wasn't doable - otherwise you'd have already done it.

Btw...cpu is incredibly light for the types of effects possible with zebrify.
