Tyrell N6 is u-he’s free virtual-analogue synthesizer, built around a compact subtractive layout with two oscillators, ring modulation, a characterful filter, unison, modulation and chorus. The current 3.0.0 beta modernizes the classic freeware instrument for today’s systems while keeping the fast, single-panel workflow that made it popular.

Why Tyrell N6 is still worth downloading
Tyrell N6 comes from an unusual origin story. The synth began as a community hardware concept developed with Amazona, then evolved into software when u-he provided the synth engine. That history explains the design: instead of presenting hundreds of pages and hidden tabs, Tyrell keeps the important synthesis controls visible and encourages quick sound design.
The instrument uses two oscillators plus noise and ring modulation, a mixer with overdrive and filter feedback, a twin filter related to an early Diva model, two LFOs, loopable envelopes, a compact modulation matrix and three chorus modes. There is also unison for up to eight voices and a large factory library with more than 580 presets.
Best uses
Use oscillator detune, filter feedback and envelope movement for solid analogue-style low end.
The envelopes, ring modulation and chorus make bright, animated patches quick to build.
Unison, slow modulation and the chorus section can create wide sustained textures without a complicated routing page.
The mostly single-panel design makes signal flow easier to understand than many larger modern synths.
What changed in the current version
u-he’s 2025 beta brings Tyrell N6 up to date with improved VST3 support, CLAP support, native Apple Silicon support, a modern preset browser, better interface performance, more GUI scaling options, MTS-ESP microtuning and an updated factory library. It remains a genuinely free download and does not require a serial number.
Windows: VST3, plus 64-bit CLAP and AAX.
macOS: AUv2, VST3, CLAP and AAX, 64-bit.
Linux: VST3 and CLAP, 64-bit. u-he describes Linux support as beta.
Version checked: Tyrell N6 Beta 3.0.0, revision 16976, released March 18, 2025.
Quick start
- Load an init or simple preset and keep oscillator 1 active.
- Set the filter cutoff and resonance before adding modulation.
- Use the filter envelope for plucks or bass movement.
- Add oscillator 2 for detune, intervals or ring-modulated tones.
- Finish with a small amount of unison or chorus instead of widening everything at once.
License and download
Tyrell N6 is distributed by u-he as freeware. The current download is hosted on the official u-he product page, where Windows, macOS and Linux installers are available. No serial number is required to unlock it.
A Producer’s Take
What I like about Tyrell N6 is how quickly it gets to a convincing analogue-flavoured patch without hiding the modulation. For basses, plucks and slightly unstable leads, the focused layout can be more inspiring than browsing through a huge multi-page synth.
