How do you make a free-running LFO in Zebra? The LFO has "Restart" in the upper-right corner but I can't figure out how to change the value.

Try using a global LFO (shared by all voices) for what you want to do

Oh, I see. That's like LFOG1 and LFOG2? It sounds like that's doing what I'm after.

Yes! The "G" in LfoG is for "global" which means it's the same for all voices.

Free running Lfos *per voice* are more like randomly phased Lfos because the voices are iterated from note to note. Unlike an analogue synth, Zebra (and 99.99% of its digital siblings) puts idle voices on stand by so Lfos, filters etc. don't use any cpu. These breaks make freely running oscillator phases appear to be random.

Ah, that makes sense. It certainly seemed a bit weird, that's for sure.

Thanks for your explanation!

Yes, it is. Free running voice LFOs vs. global LFOs is the top most frequently asked question ever since I deployed the concept in 2003 or so. I recently came up with a concept to finalize the issue, but I havn't implemented it yet.
