Diva 1.1 - Grand Performance Boost

up to 40% less CPU

Good news! Here's the Diva update you have been waiting for. We locked ourselves away in our lab and squeezed as many CPU cycles out of Diva as humanly possible, all for the sake of one thing: Performance!

Diva 1.1 is now ready for download on her brand new product page. As always with u-he products, the update is free. Simply download the appropriate installer, follow the instructions and you're good to go.

Note: We have also made subtle changes to the basic sound quality, improving the transient behaviour and adding some "sheen". Although these changes will certainly be recognized as improvements, we recommend that you render your existing projects before upgrading.

The most important changes are...

1. Multicore Support

Finally play as many voices as you like on selected systems. Requires multicore system with on-CPU memory interface e.g. i5, i7, Nehalem.

2. up to 40% less CPU usage on expensive presets

We have improved the feedback prediction algorithim in the filters so dramatically that highly resonant patches will now use up to 40% less CPU than older versions. Can't get that sound any faster now!

3. Improved sound quality

Diva 1.1 sounds like a freshly refurbished piece of analogue hardware. We've polished the attack transients and added a bit more sheen to the VCO models.

Actually, what happened is this: To improve on the crossmodulation behaviour of early betas, we abandoned the widely used miniBLEPs in favour of a version with a more accurate phase response. A few people noticed that Diva's release version (1.0) sounded a tad duller than the beta, so we have fixed that. Now she has all the glamour of those early betas, plus all the goodness that we added in the meantime.

Mix & Match

All modules in the upper rack can be replaced – send any of the oscillator models through any filter model to any amp / envelope model.

The rack also offers highpass filter models (pre or post main filter) or feedback from output to input.


This is where a LOT of Diva’s magic happens – Diva's zero-delay-feedback filters set a very high standard of authenticity.

Each filter type closely models a classic analogue hardware filter (or two): You can already choose between Ladder, Cascade, Multi-Mode, Bite... and more are planned!


Two envelopes, one for the output amp and the other general-purpose. Again, there is a choice of several different models based on classic hardware synthesizers.

The characteristics of amp and filter envelopes within the same synthesizer often differ. This important detail has also been carefully modeled.


3 x analogue chorus, 2 x analogue phaser, plate reverb, stereo analogue delay, rotary speaker emulations...

The two effects are arranged in series – you can even use two plate reverbs, one after the other.


The optional multi-threading feature lets Diva distribute her voices across multiple cores, so more voices can be played simultaneously without overloading the CPU.


Modulation processors: Rectify, quantize, multiply, invert, lag, add modulation sources before using them.

There are also several modulation options here that aren’t available in all the main panels (e.g. filter resonance, feedback).


Diva shows her most esoteric side here as she saucily flashes those voice activity indicators!

As well as detuning individual voices, a voice-specific offset is applied to cutoff, envelope times, pulse width and glide.


Every synth needs an oscilloscope! Diva has a no-nonsense 'scope that only requires two knobs – frequency and scale.


Diva comes loaded with over 1,200 presets sorted into various categories. Select a folder from the bottom left panel, then a preset from the main area.

Atmos Soundset

★ ★ New soundset for Diva now available: Atmos. Sound designer and composer Bjulin created 128 new presets for Diva. Atmos travels through spaces, both the real and the fantastical. Each preset permeated with a sense of space and mood.

Check out Atmos.

Why she's hot!

  • authentic, unrivaled analogue sound
  • up to 40% less CPU-hit than version 1.0
  • multithreading support for modern CPUs - more polyphony, less overload
  • even bigger library of gorgeously organic presets
  • the essence of 7 or 8 vintage synths for about 1% of the cost
  • ...and so much more!

Urs & the team


DIVA is *extremely* demanding on CPU

Despite exploiting all conceivable opportunities to make Diva run as fast as possible, the level of analogue simulation we put into her simply requires extraordinary CPU power. Even if the multicore/multi-threaded option works fine on your system, please consider "freezing" tracks to lower the burden she puts on your CPU. After all she's a Diva, and Divas have DEMANDS!

Finally – Diva's demo restriction is a mild crackling sound that appears at irregular intervals.
