Zebralette 3

Post

Hey everyone,

it's time for a quick sanity check of the Zebralette 3.0 release candidate.

After roaming the beta pastures for the last two years, we aim to officially release the little horse into the wild next week. If all goes well, its big brother might then also leave the u-he stables for the very first time. :hyper:

License Cards

There is one big change that will be introduced with Zebra 3: license cards.

We will gradually switch from the old username and serial number system to one that holds all your licenses on a single license card image file. This will greatly simplify the registration process, and can already be tested with Zebralette by those who are eligable for a free Zebra 3 upgrade.

Some other important details you need to be aware of:

We cleaned up the automation parameter list. Some parameters which didn't belong there have been removed. This means, other parameters got new parameter IDs. Existing projects might now automate a few wrong parameters.

We also unified the behaviour of trigger sources, which can result in slightly altered behaviour. Bipolar trigger sources will now cause a trigger on their way up through the zero crossing. Unipolar parameters will cause a trigger on their way up when reaching the 50% mark of their parameter range. If you used the MSEG as the S&H trigger source in the mod matrix, you might have to adjust the MSEG curves to get back to the same sound as before.

There are many more changes and fixes under the hood, but I don't want to bore you too much. So here we go:

Downloads:

The 3.0 release version, revision 20399, can now be downloaded directly from the product page:

Let us know if Zebralette still crashes or behaves in unexpected ways.
But make sure to check the known issues section first.
We'll further improve Zebralette in the coming months, of course.

Improvements & fixes since the last public beta:

* Improved CPU performance
* License card import feature added
* Osc wavetable mode: phase modulation added to modulation target list
* Osc wavetable mode: DC block option added
* ModNoise modulation source added
* User definable MIDI control modulation sources expanded (added Ctrl C&D)
* MSEG single trigger mode has been removed
* MSEG can be used as VCA source now
* Osc FX bypass button added
* S&H trigger system has been improved
* New preferences for mouse wheel and trackpad handling
* New preference for animation handling
* New preference for reset behaviour on playback start
* Countless other small improvements & fixes

Known Issues:

* Wave file import is an experimental feature (expect glitches)
* Possible crash related to the Undo/Redo system
* Rare plug-in loading error in Cubase/Nuendo (you can load the plug-in onto an empty instrument track instead)
* Plot graph can cause audio glitches on Linux (you can switch it off to fix it)
* Mod depth indicator glitch when swapping Osc FX slots
* Mouse cursor quirks in Pro Tools on Windows
* Preset menu icons are missing on Linux
* Some quirks in the curve editor
* No MPE support yet

Enjoy,

Try to uninstall and reinstall the plug-in. The beta tag is gone. It's possible that the uninstaller that runs during installation didn't catch all files.

Wrong place moved to bug reporting

Nice update!
I'm glad to see new knob behaviour, where the mouse cursor itself doesnt move to the edges of screen.
Much smoother experience for me at least and thanks for taking my suggestion into account (unless it was already planned^^).
Definitely looking forward to zebra 3.

PS: I love "pro solo" preset from mister Scarr.

I can't seem to find any real bug (other then the ones in the known issues section). There is one 'thing' though; whenever i move a knob/slider, the fps is going down severely (~10 to 15 fps), not the plugin, but my DAW (fl studio, latest)

Dunno... it's entirely possible that we'll have to rewrite our UI Rendering environment for Windows and maybe also Linux next year.

Same here. "BETA2" tag appears in the Preset view.
Win 10, Bitwig, CLAP, x64

Just opened the plugin and most of the knobs are off-center by a little bit, don't know if it's just temporary but I post it just in case someone else has this thing going on! I compared it with the user manual and indeed it looks different and slightly off.
