Uhe Zebralette 3 Beta 2 macOS Linux Win

u-he Zebralette 3 Beta 2 is a free spectral synthesizer for producers who want to explore oscillator-based sound design without buying another instrument. Its single-oscillator approach offers a focused way to experiment with waveform curves, spectral processing, and both additive and wavetable rendering. It suits hobby musicians looking for a free synth to learn with, as well as producers who enjoy building their own sounds.

Beta 2 improves CPU efficiency and adds a dark interface skin, alongside more presets to explore. Sound-design changes include a curve maths parameter, swappable oscillator-effect order, and a visible curve morph position indicator. You can also disable the waveform plot, while a new Showcase smart folder helps organize preset browsing.

This update refines ADSR timing and editor copy-and-paste behavior. It also addresses crashes involving preset changes, multiple open instances, and renderer switching, plus a memory leak and several modulation and oscillator-effect issues. As a beta release, it is best tested in your setup before relying on it for important sessions. The listed Windows package includes AAX and CLAP formats; check your host’s format support before installing.
