Zebra LFO offset?

[bg]

I don't know if "LFO offset" is the proper term, but I'd like to know if Zebra2 has a way to offset an LFO such that you could, for example, create vibrato that goes sharp of the mean pitch, instead of equidistant.

Thanks.

So, instead of a 12 cent variation above and below 0 cents, you want the pitch to start at 0 and fluctate up to 12 and back? If so wouldn't the same effect be achieved by setting the base pitch to +6 cents, and then reducing the LFO amplitude so it only goes +6/-6 in either direction?

That would work except for the cases where you'd want to introduce the vibrato with the modwheel. In that case the sound would constantly be 6 cents off.

Correct, Jupiter8.

LFO offset is useful for imitating rock (as opposed to classical) guitar vibrato wherein the vibrato is practically all sharp. But sounds cool.

I didn't see LFO offset in the Zebra manual, and I'm just starting with the Zebra2 demo. Thought there might be a way...

With the "normal" LFOs this is only possible for the saw models (there's one for up/down each), but you can easily accomplish things with the user mode. Switch it on and set "Wave Mode" to "lines". Then, depending on what you need, adjust the amount of steps and draw in whatever you like.
In user mode, you can easily just oscillate in one direction.

Yeah? Then route pitch to the modwheel too. Too much math though maybe. Usually there are monopolar modes on LFOs. Im not sure about zebra though.

Thanks, Sascha. I'll take a look at this.

I'm collecting quite a few tricks using the mod mixer (including, if I remember rightly, guitar-type vibrato, mod-wheel/aftertouch crossfades etc.). Can't check right now because my splitter died on me - no internet, no phone (yet)
I'm not at home right now.

BTW: For offset vibrato, you could always simply add some mod-wheel to pitch or detune.
