Report bugs here! Or send them to support at u-he dot com

But please check if the bug has already been known or reported:

Known Issues:

• The preset adapter to load Zebralette 3 presets inside Zebra 3 is still work in progress
• Sample import is an experimental feature (expect glitches)
• Filter FM can break the filter, be cautious when using it
• Don't rely on undo/redo yet, not everything will work there
• There are some rare unresolved random crashes (save your work regularly)
• There is a rare plug-in loading error in Cubase/Nuendo (load the plug-in on an empty instrument track instead)
• Animations might be slow on some Windows systems (there's a preference to switch them off)
• The filter palette is missing parts of its UI after reopening the GUI (open filter 1 palette to fix it)
• The key control selection box does not adjust its position when using the scrollbar
• The plot graph can cause audio glitches on Linux (you can switch it off to fix this)
• The preset context menu misses the favourites and junk icons on Linux
• The Pitches page UI is very broken on Linux
• There is a modulation depth indicator glitch when swapping Osc FX slots
• There are some mouse cursor quirks in Pro Tools on Windows
• There are some quirks and small bugs in the curve editor
• The Textureverb freeze button graphic can get stuck on Windows
• Guide curves are currently only saved for MSEG 1, not for 2-4
• There are no module presets for curve sets yet
• No multicore support yet
• No MPE support yet
• All the Gremlins we didn't catch yet

Are the oscillator solo buttons perhaps not working in r20399 on Win64?

Tweaking the Curve Morph button often results in audio dropouts/overloads, the signal then never comes back and one has to reload the patch - if saved before

I have had the same, but only on the CLAP variant. Didn't have the issue with the VST3 (windows 11)

Firstly, congratulations on the release! Secondly, I am unable to replace the Beta License with my own License Card. Initially I licensed the beta with the Beta card because I was waiting for support to work out some missing licenses on my account, but upon resolution and subsequent downloading of my own card, I am unable to replace the Beta license. Win 10 PC workstation. Installing only VST3 in Live 12.3.1 -- of course I can ride on the Beta License for now, but I thought I would inform here in case others experience the same issue. Again, I already mailed support just now regarding this, incl all the various courses of action I have tried with uninstalling and reinstalling the VST3. Whatever I do, I can not rid myself of the Beta License. At least the data window still says "Beta Tester" even after importing a "non-beta serial..." Just a head's up. Thanks for unleashing this wild Zebra nonetheless!

In my case it was the AU version.

Yeah, the beta tester serial is probably *newer* than your actual serial. No worries though:

- our support team can tell you how to manually remove the beta card (I'm not familiar enough with Windows...)
- when Zebra 3 gets released, the beta card will not work in it, and then the other card will take over (I hope...)

So it's not per se a bug, I should have just back dated the beta card

It's a special case... I have the preset, there's something going on that I can't explain yet, using the Curve Spectrum as source for almost the init preset. I'll look into it once the dust settles a bit...

I cannot get the Hold Pedal modulation source to actually do anything. While playing notes, none are held when I operate the pedal. I have verified (in Reaper, using ReaControlMIDI) that Reaper is actually receiving the correct MIDI data (CC #64; On = 127; Off = 0). I observe the MIDI indicator in the GUI illuminate when I operate the pedal. If I drag from the 'Hold' icon in the bottom row of the GUI and drop on a control, a slot is created in the matrix. But no matter how I manipulate the controls in the slot or in the target module, there is no response.

Congrats Urs BTW. This is a dream come true.

I personal hate that if you move the knobs, the knobs move while the pointer stays still. This isn't how it works in Zebra 2...not sure if that's a bug though

[Chris-S]

The Control A/B/C/D knobs on the perform-tab are not moving with MIDI.

VSTi3 fails plugin evaluation in Digital Performer 11.35 on Mac OS Sequoia 15.6.1.
works fine as an AU.
