u-he zebra 2 bipolar glide 2 knob, what does it do? how does it work?

[rmak]

Hi, I am new to the forum, so I apologize if this post is not to the right standard of a good post.

In the u-he zebra 2.9 manual, it states "Glide, Glide2 - A smooth pitch transition between consecutive notes. Glide affects the Key Follow modulator, so it is applied to all modules that include this parameter (OSCs, FMOs, Combs, VCFs and XMFs). Glide2 is a bipolar offset for the even-numbered modules. The modulation source KeyFol2 is the same as KeyFol, but includes the Glide2 offset."

Does this mean glide 2 only affects keyfollow on Osc and FMO 2 and 4? Why is it bipolar, how does that work? I am also not completely sure what keyfollow means as it relates to glide. I know key follow on cutoff opens up the filter more as you move up in pitch, but what does that mean on glide? Does it have more to do with more glide when intervals are greater on the keyboard, 3rd vs an octave for instance? Any help/explanation would be greatly appreciated. I just bought zebra and am trying to go through the manual.


Thanks,
Ricky =)

Yes, you got that right, Glide2 applies to Osc2, FMO2, etc. The knob is bipolar, so that you can offset the glide of those Oscs and FMOs in both directions. You can either set it shorter (negative value) or higher (positive value) than the "normal" glide

The relationship between glide and keyfollow simply means that keyfollow also follows the glide. If you have a filter with keytracking and have a high glide setting, for example, when you press a higher key, the cutoff of that filter will not just jump to the new frequency, but "glide" to it in the time specified by the glide parameter

Keyfollow2 is the same thing but it uses the value from the glide2 instead of the "normal" glide.

Darn, that could have been explained better! It's late here. Someone will probably explain it better soon!

Thank you for the quick reply Guy. I guess I'll move on and read on in the manual as there is a lot of content! I assume glide 2 is more intended for the oscillators when they are set up in serial as opposed to parallel, and "offset" in glide 2 is meant to make the effect of glide 1 less obvious to a listener. It also doesn't seem to matter if you have keyfollow 1 or 2 set up anywhere as a modulation source... But I think I'll understand these knobs more as I use this plugin more. I just wanted to get an idea of how glide 2 was intended to be used within the context of sound design or this plugin.

If anyone has more input, I would greatly appreciate it. Cheers - Ricky

Thank you Guy for that explanation of the filter, that helps me. I will keep that in mind as I program and learn zebra2

For instance, try OSC2 (and maybe OSC4) --> VCF1, then only glide the cutoff by turning Glide up and Glide2 way down.

Thanks Howard for the suggestion. I did what you stated, and it is a bit confusing that both glide 1 and glide 2 knobs are affecting the glide for combination Oscillator 2 with VCF 1 or VCF 2. Then I tried the same with Oscillator 1 with VCF 1 or VCF2, only the glide 1 knob works, so glide 1 knob seem to affect all and glide 2 just the even number oscillators. I'll just keep this in mind as I work with the knobs in the future.

glide 1 knob seem to affect all and glide 2 just the even number oscillators.

Of course. Quoting the manual (recommended reading):

Glide, Glide2
A smooth pitch transition between consecutive notes. Glide affects the Key Follow modulator, so it is applied to all modules that include this parameter (OSCs, FMOs, Combs, VCFs and XMFs). Glide2 is a bipolar offset for the even-numbered modules. The modulation source KeyFol2 is the same as KeyFol, but includes the Glide2 offset.

Thanks Howard, I think I understand this better now, so basically anything you put key follow or key follow 2 on as a modulation source will be affected by the glide 1 and 2 knobs, respectively, in some way. But you don't necessarily need key follow on as a modulation source to implement glide; when you turn the glides knobs, you will still have that glide effect with or without key follow set as modulation sources. It wasn't as clear the first time I was going through it in the manual. I think I just need to get in there and turn all the knobs! I am trying to reverse engineer some of the patches in the dark zebra.

basically anything you put key follow or key follow 2 on as a modulation source will be affected by the glide 1 and 2 knobs, respectively, in some way.

Well, almost. "respectively" is wrong, as anything that uses key follow 2 is ALSO affected by "Glide" (as well as the offset "Glide2")
