Overview

The Klavis Logica XT is a 5HP Eurorack logic and gate processor. It builds on the earlier Logica in the same width and is aimed at modular users who want Boolean functions, gate and trigger shaping, controlled randomness, a flip-flop and a digital delay line in one compact, low-power module. It is available with a choice of two panel finishes.

  • 14 modes: six basic logic functions, two forced states (on and off) and six advanced sequential functions
  • Three normalised inputs plus a manual button: the button acts as a fourth input, and normalisation works whatever order the jacks are patched in
  • Three outputs: Out, an inverted Inv output (for example And and Nand at once) and a dedicated Div/2 output
  • Voltage-controlled mode selection: the Mode pot is summed with a bipolar CV input that steps through the simple functions
  • Audio-rate processing: runs from DC to beyond audio, so it handles oscillators as well as gates and clocks
  • Memory: settings are kept in non-volatile memory and restored after a power cycle

The simple functions cover Or/Nor, Xor/Xnor, Even/Odd, 1 High, 1 Low and And/Nand. The Xor works across all three inputs, which gives different results from chaining two 2-input Xors, and patching oscillators into it turns the module into a digital ring modulator. The Div/2 output is useful for clock division or for deriving a sub-octave from an audio signal.

A short press of the Xtra button switches to the advanced column; holding it lets you edit the parameter of the active function. Gater behaves like an Or but retriggers on every new gate, with an adjustable gap. Gt~Tr converts gates to triggers and triggers to gates, with pulse length set from 1 ms to 10 s. 1,2,3 only opens the output once inputs fire in sequence, Coin passes signals at random with 50%, 25% and 12.5% odds per input, and S/R+C is a flip-flop with clock, set and reset.

D.S&H is a digital sample and hold that can delay patterns by 1 to 128 clock steps or work as a delay line of up to 5000 steps. Without an external clock it runs at 1 kHz for delays of about 5 s; slower clocks stretch this further. Outputs can be combined passively with a multiple or stackable cables, and LEDs show the current mode and the state of every output.
