Graphical Linux bug: Right-click menus stay on top of everything when changing windows under GNOME Wayland (only tested with REAPER now, will report back if it's any different in Ardour).

That's on purpose.loctune wrote: Mon Mar 23, 2026 4:43 am Editor bug: move a point into the vertical borderlines causes other points on the borderlines to disappear.
The first point and the last point already form a line. It can be made visible either on the front or the back, using the "Close Shape" options at the bottom of the toolbox.
So because there is a line already, the point that is disappearing gets removed because it is on that line. The editor automatically removes excess vertical points as they won't be audible - the curve will jump from the first point of the vertical line to the last.

Macro knobs retain their position from preset to preset - is this intentional? I just noticed it.
Sounds are altered. (it isnt just knob position)

This will change in the final version. We’ll reset MIDI controllers on preset change.Milkman wrote: Wed Mar 25, 2026 7:20 am Macro knobs retain their position from preset to preset - is this intentional? I just noticed it.

First of all: thank you u-he team for the fantastic plugin. I've been enjoying the beta versions a lot, the past two months or so. 
Yesterday I ran into a freeze issue that is quite reproducible. My friend and I were exploring the Curve Editor, on our two individual Macbooks (M-series), using Ableton Live 12. I used Zebra 3 Rev 20977 AU.
Our question was: how to shift the phase of the waveform. We found the Rotate tool to do so, but every time after playing around with it a bit – by dragging Points left and right – the endless beach ball appears and Activity Monitor says "Not Responding". Audio keeps playing.
As for reproducing the issue: it takes about 30 seconds of using the tool to trigger a freeze. Perhaps combined with switching windows / playing midi notes / having the transport control set to play.
I was also wondering if this bug could be related to not being able to drag (phase rotate) the waveform from the most left and right points. It would feel intuitive to me, and in this Beta the mouse cursor already changes to the Rotate tool when hovering over the outer points.
Cheers,
Rutger

On Linux, switching to the init patch swaps many parameters from the previous patch.

Are you using Bitwig and Zebra's CLAP version? In this case, this is a bug in Bitwig, not in our plugin. It's caused by the Undo/Redo system they introduced with Bitwig 5.3. Please contact Bitwig about this.Indanautilus wrote: Sun Mar 29, 2026 9:34 pm On Linux, switching to the init patch swaps many parameters from the previous patch.

Ah, yes! Thanks for pointing that out. In Reaper, initializing Zebra works as expected.

I get DAW crashes when browsing presets. Seems sort of random, but rather consistent. I can go through 3-4, maybe 5 presets just fine, and then suddenly, the next one will crash the program (suing the Next preset arrow). Doesn't seem to be a pattern or tied to specific presets.
