Authentic re-creations of Klavis Eurorack modules
Compact multi-algorithm modules with unique functionality
Flexshaper
Klavis Flexshaper is a CV-controlled voltage mapper and waveshaper. An input signal is shaped according to five points, which can be adjusted and CV-controlled.
The input signal can be unipolar (0–10V) or bipolar (-5–5V). Clip lights indicate whether the input signal is outside or within the selected range. Up to 10x gain can be applied to the input signal.
Supports polyphonic cables.
For full details of functionality, see the hardware Klavis Flexshaper page and manual (PDF).
ComPair
Klavis ComPair can be used as a window comparator, which checks whether an input signal is between two voltages, or as two independent comparators.
When the A voltage is greater than the Hi voltage, a gate is emitted from Hi. When the B voltage is less than the Lo voltage, a gate is emitted from Lo. The Hi voltage can be offset by CV.
You can invert or mute each output gate with three-way switches.
Output anti-aliasing is enabled by default, which improves the sound of audio-frequency signals. To disable, right-click on the panel and select “Anti-alias”.
Supports polyphonic cables.
For full details of functionality, see the hardware Klavis ComPair page and manual (PDF).
Two Bits
Klavis Two Bits is a dual logic processor with two inputs per section and 15 different functions. The two sections can be chained, giving the second section a virtual input.
Adjust or right-click the function knobs to change the section’s function.
Certain functions have settings and CV control. To change function settings, right-click the panel or click the Set button. Functions highlighted in red in section 2 use a CV signal for input 2B.
For full details and a description of each function, see the hardware Klavis Two Bits page and manual (PDF).
Logica XT
Klavis Logica XT is a logic processor with 12 functions and three inputs per function.
The Xtra button toggles the left/right function bank. The Manual button serves as a temporary additional gate input, and its behavior depends on the selected function. Certain functions have settings that can be adjusted by right-clicking on the panel.
In Set/Reset + Clock mode, inputs 1/2/3 serve as Clock/Set/Reset gate inputs. In Digital Sample & Hold mode, they serve as Clock/In/Clear gate inputs.
For full details and a description of each function, see the hardware Klavis Logica XT page and manual (PDF).
Tweakers
Klavis Tweakers is a dual-section utility that can apply gain, offset, polarity inversion, and muting to CV or audio signals.
Each section can apply up to 200% gain and between -5–5V offset to the input signal. You can invert or mute the output with the three-way switch.
Input B is normalled to input A, so a single signal can be distributed to both outputs with different adjustments. If output A is unpatched, it is mixed (added) into output B.
Supports polyphonic cables.
For full details of functionality, see the hardware Klavis Tweakers page and manual (PDF).
Mixwitch
Klavis Mixwitch is a dual 2-input mixer with the ability to switch (toggle) inputs using CV or clocks.
Up to 200% gain can be applied to each input. Click the polarity button to invert the input. Click the Off button to mute the section’s output. Enable Log mode to make the gain knob use a logarithmic response and use decibels (dB) instead of percentage (%).
If output A is unpatched, it is mixed (added) into output B.
Click the Switcher button to cycle between switcher modes. The CV/Clk input selects the active input.
- Off: All inputs are active.
- CV, 4 channel: CV of 1V, 2V, 3V, and 4V activate inputs A1, A2, B1, and B2, respectively.
- Clock, 4 channel: Each trigger activates the 4 inputs in a cycle.
- Clock, 4 channel, random: Each trigger activates the 4 inputs at random. The next input is guaranteed to be different than the last input.
- CV, 2 channel (B): CV of 1V and 2V activate inputs B1 and B2, respectively. Inputs A1 and A2 are always activated.
- Clock, 2 channel (B): Each trigger toggles inputs B1 and B2. Inputs A1 and A2 are always activated.
Supports polyphonic cables.
