Nektar BOLT is the first Harmonics Synthesizer for VST/AU compatible DAW platforms. Its unique Harmonics oscillators will take you from subtle sine waves to overtone-rich pulse chains at the turn of a knob. And BOLT’s user interface encourages instant experimentation when creating sounds. No filter required – it all happens right in the oscillator. Experience the speed of new sounds – literally.


Experience BOLT’s new Harmonics Synthesis engine with its rich, organic sound and lots of unique character – no traditional filter required.


No PhD in sound design required: Rediscover the fun in tweaking your own sounds with BOLT’s streamlined user interface.


BOLT comes with 500+ factory & artist patches for all kinds of genres. From lush pads to deep basses – and screaming leads to sound effects.



BOLT’s synthesis engine generates a sound’s overtone structure directly in the oscillator. So you won’t find a filter section like in typical subtractive synthesizers.

The unique Harmonics Oscillator takes care of it all – just by turning the HARMONICS and ROLLOFF knobs you change a wave’s shape and core sound from subtle sine to bright pulse chain. ODD switches the oscillator to create odd harmonics only, If you additionally bring in DEEP, you will notice the waveforms to resemble saw or square shapes (with ODD active). In addition, each oscillator has its own amplitude envelope. So all you need for creating the core sound is right there!


Sounds come to life with modulation: So BOLT offers four powerful modulation generators. Its 3 LFOs and one Modulation Envelope Generator ensure a host of modulation possibilites. No matter, if you are after snappy transients or would like to modulate different aspects of the sound all at the same time – you can do all of that and more. The modulation generators can even modulate each other if you want to push the envelope. The best is, that it’s easy to experiment: Modulation Targets are pre-assigned, so you simply need to bring up a target amount to hear an effect.

The MODULATION EG is modeled after classic ADSR envelopes and cover a range from ultra-snappy and percussive to lush sound scapes. The 4 modulation Targets can be assigned to many destinations, including LFO Frequency and Intensity.

BOLT’s Low Frequency Oscillators go beyond the range you’d expect from a typical LFO. They offer an extended range from 0.01 Hz up to 10 kHz. So they go well into the audible range which allows for some extreme modulation effects, including amplitude and frequency modulation.

Choose from 13 different waveforms, including Random and stepped waves. Switch Cycle off to use the LFOs as additional auxiliary envelopes – or sync them to the beat. Of course each of them can be synced differently, so you can create interesting poly-rhythms. You can even assign them to cross-modulate each others tempo. You’ll probably never run out of new interesting modulation combinations to try out…


Four integrated effects processors ensure that BOLT’s patches are ready to be dropped into your productions: EQ, CHORUS, DELAY and REVERB provide the essential effects at your fingertips.

The effects are optimized ease of use, only 3 parameters per processor ensure you’ll get to results quickly. Still you’ll find enough tweakability including tempo sync for the DELAY or parametric and bandpass modes for the EQ.

There’s a lot more we could say about BOLT – but it’s all about the sound isn’t it? So download your trial version and listen to it yourself!


Barry Burns // Mogwai
“Within 5 minutes of using this synthesizer I had something that I used with Mogwai straight away – it was really easy to get something usable. It is an unusual process of making a sound up, which is way more interesting than on a usual synthesizer. My favourite thing probably is the LFO function,

there’s 3 LFOs and you can assign them to pretty much anything. (…) I plan to have it on most of the next album.”

Martyn Ware // Heaven 17, founder The Human League
“Bolt is a very interesting software synth, which has quickly become one of my ‘go-to’ tools for inspirational composition. The GUI design is elegant and easy to use for oldschool analogue synthesists like me…and the factory sounds are very well-considered and eminently usable. Most importantly, there is an indefinable ‘warmth’ to the sounds which is redolent of my early experimentation with 1970’s modular synths. Well done Nektar!”

Julian Wassermann // Techno DJ and Producer
“Used this monster on several new tracks and I’m blown away by its modulation possibilities. Especially the LFO cross modulation and sync features. I include Bolt in all my productions right now – I’m totally impressed. I’m in love with Bolt!”

John B. // d&b DJ and Producer
“The most inspirational synth I’ve used in years! A quick session just browsing factory patches has already led to ideas for 5 new tracks. Love it!”
