After years of working as subcontractors 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 CalTrans Klavis  Jun 25th, 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, 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 
  • Klavis Quadigy Klavis  Dec 22nd 2019, 16:47
    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.

    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.

    Firmware update 1.33! Our flagship Dual VCO/LFO gets even better. We've added new scales to the quantizers (yes, there are 2 quantizers). You can now reset your module to factory default settings. We have also completely upgraded the Base Note handling. Puzzled? we have expanded the User Manual! It now includes tables for all LED meanings and buttons use in every context. Thanks to the community for all the feedback; we love you! 
  • Klavis Logica XT Klavis  Sep 10th 2018, 17:02
    The Logica XT is the upgraded version of the Logica Gater. There ares 5 new functions for a total of 14, with some never seen before. Users can now define the polarity of the manual button. Pulses become time adjustable. The digital sample & hold has a 5000 step delay line. Processing rate it is 10 times audio rate. User settings are automatically stored in non-volatile memory.

    Update 1.24 allows any combination of algorithms in the two oscillators. This is the full-featured implementation we worked hard to deliver. Thank you for the feedback and kind words from our supporters. 
  • Klavis Twin waves Klavis  Oct 11th 2017, 17:06
    Firmware update 1.20 brings two new features: VCA capability is the unexpected and apparently very welcome one! The other feature concerns the user interface: it is now possible to lock the settings of tuning pots independently in each osc. This was requested by users plyaing tonal music and wanting to preserve those fine settings. As usual, the update is done by simply playing an audio file through the front panel. Enjoy!

    Firmware update 1.13 brings new scales to the Twin Waves quantizers and it is now possible to see the full name of scales with the usual scrolling help. Get it here: http://www.klavis.com/images/TwinWaves_1.13.zip On an unrelated note, did you know that in LFO mode, using external clock, the wave cycle can be several days long ? That's thank to the clock divider that goes to 64.
