1.2.0 Krotos Audio Concept


Krotos Audio Concept

Synthesis In Motion

Concept is an intuitive and creative soft-synth, that makes the process of creating your own patches fast and inspiring. Concept’s flexible synth engine will enable you to create everything from traditional synth sounds to more complex evolving textures and custom sound design elements. A fresh approach to modulation allows any parameter to be mapped to one of four highly editable multi-mode modulators in the centre of Concept’s UI. Choose from a variety of flexible modulation options such as an Envelope/Pitch Follower, an X/Y Capture pad and the unique ‘Tweak It’ customisation system.


Explore a new approach to modulation using drag-and-drop. Instantly identify your mappings with clear colour coding and animated visual feedback.


Draw your modulation movements within an X/Y field. Capture patterns for any combination of parameters and sync the results to your projects tempo. Create unique sounds and melodies in an instant.


Stimulate new ideas by performing and modulating with any input or instrument. Use elements from your mix to create dynamic rhythmical patches, or use the pitch follower to create exciting interactions with existing melodies.


Get inspired quickly using our controllable and assignable customisation system. Create variations of your patch with a single click, with results ranging from musical to complex.



To get you started, Concept comes loaded with 200+ diverse presets. To elaborate, the presets are designed by the likes of Mercury award-winning music producer Roni Size (Reprazent, Universal), Richard Devine (Google, Warp Records), Kayla Painter (Brownswood Recordings), Dom Ruckspin (Ninja Tune) and Hieroglyphic Being (Mathematics Records).

What They’re Saying about Krotos Audio Concept

I love the simple straightforwardness of Concept, but also how you can surprise yourself by accidentally routing the wrong thing or creating blind variables and just randomizing everything. So many eye-brow-raising moments!

I love the interface and the modulation options they present in the plugin. I really fell in love with the X/Y automation mode. This spoke immediately to me.

Concept is a great tool for creation – an intuitive layout with great features like the visualisation panel. Having the parameters assigned to the colour of the LFO allows you to easily see what you’ve done to create sounds – which is super useful. Recording automation on the XY capture and reversing it was something that sparked lots of ideas for me!

Concept is an endless generator of sonic ideas. The modulation system is a win-wind deal; you’re sculpting great sounds in a breeze. Learn the basics of synthesis, while patching; this instrument is fun for every synth-lover, both beginners and advanced users.

In addition, check out Krotos Audio Simple Concept.


XY Capture is a unique modulation effect combining an XY pad with a way to ‘capture’ movements performed with this XY pad, and use this movement to control any parameter in the plugin. XY Capture allows you to go beyond LFOs, Envelopes or Arpeggiators and intuitively shape the response of any number of parameters, and record very complex, personal and performable movements. Once a movement is captured, you can edit it, sync it to tempo, adjust the speed or direction and much more. You can also use up to four XY captures in your presets. Check out some of our factory presets to see how this can be used in your own projects.


Audio Input is Concept’s quick and easy pitch and amplitude follower. This allows you to feed multiple audio signals into the plugin (depending on your DAW), and use these as modulation sources. You can choose between amplitude or pitch analysis, and assign this to any parameter to modulate it.Instantly shake up your bass patches or pads by feeding in a kick, hat or melody into it, to gel your tracks in a whole host of new ways!


Tweak it is Concept’s unique customisation system. It allows you to quickly create variations of factory presets, or your own designs, without losing the initial character of the preset. By adding a parameter to the Tweak it system, you allow the parameter to be updated within a certain range every time a Tweak is triggered. You can add any number of parameters, so you could tweak one, or hundreds of parameters inside the plugin on a single Tweak. You can tweak almost everything in the plugin, including oscillators, filters, FX, Modulators etc all using the drag and drop.

Concept 1.2.0

New Filters, Drag & Drop FX Reordering, Added Presets, MIDI Learn and a new lower price!

New Filter types added

(Formant, 12db High Pass, 12db Low Pass, 24db Bandpass, 12db Bandpass)

Extend your creative palette with filters that mimic the human voice (Formant) or give you more control over shaping your sound. The new additions to the Ladder Filter (for High Pass, Low Pass and Bandpass) are all equipped with Drive, to push those aggressive synth sounds even further. Remember that these new filter types can also be used in the ‘Filter’ in the FX rack, giving you up to 4 filters run in series or parallel!

FX Rack Reordering with drag and drop

Simply grab the ‘double headed arrow’ in the corner of any FX rack, and drag upwards or downwards to change the routing of your FX on the fly! This is a fantastic way to explore Concept’s in-built FX and can produce some exciting and unexpected results at high speed.

Midi Learn added

Simply right click on any parameter and assign it to your MIDI controller from within Concept. You can also save and recall these mappings from the Menu. MIDI mappings are saved across presets and in your session, improving speed and flexibility of work.

Active/inactive states in Oscillator and FX rack UIs for improved workflow

Now it’s easier than ever to track what is happening in Concept. Any inactive section of the plugin (including all Oscillators and FX) will ‘grey out’, so you can quickly see at a glance what is affecting your sound.
