How to Use u-he Diva Properly: Modules, Settings and Workflow

Most people open Diva, scroll presets, maybe turn the cutoff, and close it again because it eats CPU. That's a shame, because once you understand how it's put together, Diva is one of the fastest synths to get a good sound out of. This is how to use u-he Diva properly: the settings to check first, how the modules work, where the modulation hides and the workflow I use to build a sound from scratch.

How to use u-he Diva: think in modules

Diva isn't one synth with a fixed layout. It's a set of slots, and in each slot you pick a module modelled on classic analogue circuits:

• Oscillator: Triple VCO, Dual VCO, Dual VCO Eco, DCO or Digital.
• High pass filter: HPF Post, HPF Pre, HPF Bite, or no HPF (just feedback). With Triple VCO this panel is taken by the third oscillator instead.
• Filter: Ladder, Cascade, Multimode, Bite or Uhbie.
• Envelopes: ADS, Analogue or Digital, for both envelopes.

Choosing modules is choosing the character. A Triple VCO into a Ladder filter with ADS envelopes feels like a big old mono synth. A DCO into Cascade with a chorus feels like a classic poly. So the first habit: decide what kind of instrument you want before you start turning knobs. I explain each oscillator in detail in Diva oscillator models explained.

Check the Main panel before anything else

The Main panel holds two settings that change how Diva sounds and how heavy it is:

• Accuracy: draft, fast, great or divine. Draft is CPU friendly, but u-he says FM sounds rough and resonance is primitive. Great is the best everyday compromise. Divine is top quality and, in u-he's words, seldom necessary.
• OfflineAcc: same or best. Set it to best and bounces render at top quality while you work at a lighter setting.

Both are global per instance, so loading a preset doesn't change them. If a preset sounds thin or harsh, check Accuracy before you judge it. There's also a Multicore switch that can help or hurt depending on your CPU: the u-he Diva CPU guide covers how to test it.

The filters: where Diva gets its character

If you only learn one section well, make it this one.

• Ladder: a classic 24 dB per octave ladder low pass, switchable to 12 dB. It has filter FM from oscillator 1, which adds growl. My pick for basses and acid lines.
• Cascade: similar controls to Ladder but cleaner, with a Rough or Clean switch that changes the character and how resonance behaves. Great for pads and chords.
• Multimode: LP4, LP2, HP and BP modes. Handy when you need a band pass or high pass sweep inside the synth.
• Bite: looks plain but sounds very different. Its sound depends heavily on input level, the selected revision (REV) and the Peak (resonance) setting. Push the oscillator levels into it for dirty, aggressive tones.
• Uhbie: a smooth 2 pole state variable filter. The MIX knob crossfades from low pass through band reject or band pass (the BR/BP switch picks which) to high pass.

A good exercise: keep the same saw and envelope, then switch through all five filters at the same cutoff. You'll hear how much of Diva's sound is the filter.

Envelopes and the amp

Diva has two envelopes. By default Envelope 1 drives the amplifier and Envelope 2 is the modulation envelope, already available on the filter cutoff and oscillator pitch. Each can be one of three models:

• ADS: decay and release share one time. You can switch the release stage off so a long decay still stops the moment you let go of the key.
• Analogue: a full ADSR modelled on a classic analogue poly.
• Digital: an ADSR with two extra buttons: Q quantizes for a slightly steppy sound, and C curves the envelope into more of an S shape.

Two small knobs on each envelope matter a lot. VEL scales the envelope by velocity, which gives you accents. KYBD makes envelopes shorter on high notes and longer on low ones, like a real instrument.

One trick I like: in the Amplifier section you can set the VCA to a simple gate instead of Envelope 1. That frees Envelope 1 for other modulation, so you get two modulation envelopes on sounds that don't need an amp shape, like organs or plucks shaped by the filter.

Where the modulation lives in Diva

Diva doesn't have one big modulation matrix screen. Instead, most targets have their own source selector with an amount knob right next to them, and many of those amounts are bipolar, so they can push up or down. You'll find them under the cutoff, the pitch, the pulse width, the filter mix and the pan.

Source	Target	What you get
Envelope 2	Filter cutoff	Plucks, basses, the classic "dow"
LFO 2	Pulse width (Dual VCO default)	Slow PWM movement on pads
Envelope 2	Oscillator pitch	Pitch drops on kicks, toms and zaps
StackIndex	Pan Mod	Stacked voices spread left and right
StackIndex	Uhbie MIX	Each stacked voice gets a different filter response

For anything more complex there's the Modifications panel. It can Rectify, Invert, Quantize or Lag a source, and Multiply or Add two sources together. The result becomes a new modulation source you can pick anywhere. Multiplying a slow LFO by StackIndex, for example, makes two stacked voices move in opposite directions. I use that exact setup in the StackIndex dual filter trick.

The Trimmers: small knobs, big difference

The Trimmers panel is where Diva's analogue behaviour is tuned:

• Oscillator Voice Detune detunes each voice per oscillator, Detune Amt scales all of it, and Voice Drift adds a slow pitch wander. The manual says to keep Detune Amt and Voice Drift low for good tuning.
• Variance adds random per voice offsets to things like cutoff, envelope times and pulse width.
• Transient Mode decides what resets when a note starts. Analog resets nothing, like old hardware. Osc reset restarts the oscillators at the Reset Phase positions, which I use on basses and plucks so every note hits the same.
• Stack Tune sets the tuning of stacked voices.

Effects: use them for colour

Diva's effects section offers chorus, phaser, plate reverb, delay and a rotary speaker. I use the chorus a lot on pads and chords, because that's a big part of the classic poly sound. For reverb and delay I often prefer my DAW sends so all synths share the same space, but the Diva plate is nice for a quick self contained patch. Keep chorus off on basses: stereo effects on the low end cost power in mono.

My workflow for a new Diva sound

1. Set Accuracy to great and OfflineAcc to best.
2. Pick the oscillator model for the role (bass, pad, lead, stab).
3. Pick the filter, and the HPF if the sound needs thinning.
4. Pick envelope models, shape Envelope 1 for volume and Envelope 2 for the filter.
5. Add movement: LFO, velocity, key follow.
6. Fine tune the Trimmers: drift, detune, transient mode.
7. Add effects last, then save to your User folder with a clear name.

Common mistakes

Designing on draft

Your resonance and FM will change once you switch to great. Design on the setting you'll use.

Ignoring the module choice

Fighting a Ladder filter to sound like a clean poly pad takes ages. Switching to Cascade takes a second.

Too much drift

A bit of analogue wobble is charming. A lot makes chords sound out of tune.

Huge stacks everywhere

Stack multiplies voices and CPU. Two stacked voices with smart modulation is often wider and cleaner than eight.

FAQ

Is u-he Diva good for beginners?

Yes, because it's a classic subtractive synth: oscillator, filter, envelopes. The only real hurdle is the module choice and the CPU, and both are easy once you know the settings above.

What is the best Diva filter?

There isn't one. Ladder for basses and acid, Cascade for pads, Bite for dirt, Uhbie for smooth sweeps and LP to HP blends.

Why does Diva sound different from other soft synths?

u-he models the circuits in real time, so filters and oscillators react to level and resonance like analogue hardware. That's also why it needs more CPU.

How do I learn Diva faster?

Take apart good presets. Look at which modules they use and what's modulating what, then rebuild them from an init patch.

The quickest way to practise all of this is with real sounds in front of you. Start with the free Glow Diva presets. If you want the full Glow pack plus the Analog DIVA Preset Guide and a video on using Diva with it, have a look at Glow Producer Edition.
