After years of working as subcontractor for companies in the pro-audio and music domain, we enter a new venture with our original designs.
We hope that you will appreciate the care and thought we put in our products.
Please visit our website and drop us a line. It is always nice to have your feedback.

News from the Labs

  • Klavis Twin Waves MkII Klavis  Dec 17th 2021, 14:57
    Twin Waves update 1.35 allows octave selection independently for the two oscillators. This firmware update is available on Klavis.com. Think of downloading the updated user manual V1.1. - https://youtu.be/ZGyYgxaZR1k 
  • Klavis Quadigy Klavis  Aug 23rd 2021, 13:26
    The flagship quad envelope generator gets a firmware update. Now V1.23 brings various fixes and subtle improvements. Thank to Rainer for the feedback ;-) 
  • Klavis Quadigy Klavis  Apr 19th 2021, 13:08
    New firmware 1.22. The changes: 1. The Global Time setting percentage now acts on the displayed time for every other setting involved. - 2. In cycle mode, the duration of each setting is now shown as a percentage. Settings are balanced among themselves to fill 100%. - These improvements are only display changes but I believe they will make the Quadigy even more easier to use. 
  • Klavis Logica XT Klavis  Mar 3rd 2021, 11:49
    Updated user manual V1.3 - The Coin Toss function gets a table listing the odds when feeding more than one input at once. There is also a drawing to explain the practical use of the Patten Delay capability. https://www.klavis.com/all-products/logica-xt 
  • Klavis CalTrans Klavis  Jan 20th 2021, 18:26
    An update of the CalTrans manual is out. This version 1.5 corrects a mistake in the input calibration procedure description. There are several clarifications too (it's good to reread oneself after a while :-) Downloads at https://www.klavis.com/all-products/caltrans 
  • Klavis CalTrans Klavis  Jun 25th 2020, 10:15
    New firmware for the CalTrans. Version 1.17 offers: * User editable input scaling to match sources that don't generate perfect 1V per octave signals. * Complete rewrite of the main processing with higher precision. * ... and the unavoidable fixes and tweaks ;-) The updated user manual 1.4 is much expanded with operations described in exquisite details :-) Downloads at http://www.klavis.com/index.php/all-products/caltrans 
  • Klavis Mixwitch Klavis  Jan 27th 2020, 17:58
    The updated manual presents 18 applications. NEW: Digital inverter, Voltage window comparator, Drum selector, Random clocking – Chance generator, Two-input AND / NAND gate, Two-input XOR gate – Digital ring-modulator, Saw to PWM with CV control, Hard clipping; Besides: CV mixer, Audio mixer, Four step sequencer/randomizer, Sub-octaves generator, Granular synthesis, Multiple-segment waveshaper, Phase-controlled wave-stitcher, VC transposer

    Quadigy firmware 1.10 brings both requested and unexpected features. Due to its success, the Quadigy is sold out in our stock but hopefully still available at retailers. Check them out quickly, next ones won't be available before the end of February. A new video by Martin Doudoroff covers the Preset control by CV/trig and the Morphing between presets. 
  • Klavis Flexshaper Klavis  Dec 21st 2019, 16:26
    The Flexshaper is a voltage mapper and parametric waveshaper. Five settings allow you to fold/expand/clip/compress/invert partially or completely any CV or audio signal. The module can act as an envelope-shaping tool, frequency multiplier, waveshaper, clipper, distortion, limiter, curve changer, and more. Five CV inputs offer limitless control over the placement of the voltage points for dynamic signal sculpting. 
  • Klavis CalTrans Klavis  May 14th 2019, 12:59
    Having trouble playing your VCOs in tune? Would you like to easily transpose them via semitone and octave encoders? Would love making some oscillating gizmos play in tune as if they were designed for perfect V/Oct tracking? The Klavis CalTrans is here to make your life easier. It corrects and expands the V/Oct curve of up to 4 target modules (VCO or else), it offers portamento, glissando, quantizer, and presets.
