XAOC Devices Moskwa II

Eight-step roto sequencer with deep live performance powers

20 HP Eurorack module

Moskwa II is an eight-step CV and gate/trigger sequencer designed for live performance, offering per-step gate patterns (micro-sequences of up to eight sub-gates), dual randomization circuits, a built-in quantizer and slew limiter, and the ability to chain two units for up to 16-step sequences. Its musical character blends classic analog sequencer simplicity with deep programmability, enabling everything from locked grooves to chaotic generative melodies.

Features

  • Eight-step CV sequencer with per-step potentiometers
  • Parallel eight-step gate/trigger sequencer
  • Per-step gate/trigger pattern generator (up to 8 sub-steps each)
  • Custom gate/trigger sequence up to 256 steps
  • Built-in quantizer with 8 factory scales (chromatic, major, minor, major pentatonic, minor pentatonic, akebono, arabian, phrygian)
  • User-definable scales via USB and scales.txt file (firmware 1.0.5+)
  • Built-in slew limiter with portamento and glissando modes
  • Two independent randomization circuits (Rand Play and Probability)
  • Brownian motion step order mode
  • Self-creating probability inversion sequence (Prob Mode)
  • Eight preset slots
  • Built-in clock 12 to 2400 BPM

Controls & Jacks (37)

  • Step 6 CV— Sets the CV value for step 6.
  • Step 1 CV— Sets the CV value for step 1.
  • Step 4— Activates/deactivates step 4 or selects step 4 in menus. Press and hold to enter step settings.
  • Ext Clock— External clock input for tempo synchronization with other modules.
  • Direction Input— Control input to reverse the direction of sequence playback.
  • Step 2 CV— Sets the CV value for step 2.
  • CV Out— Control voltage output from the sequencer. Sends voltage for each step regardless of step activation.
  • Transport Input— Gate input to pause/play the sequence or toggle between on/pause states.
  • Step 1— Activates/deactivates step 1 or selects step 1 in menus. Press and hold to enter step settings.
  • Step 3 CV— Sets the CV value for step 3.
  • Step 4 CV— Sets the CV value for step 4.
  • Step 7 CV— Sets the CV value for step 7.
  • Patt/Preset— Activates pattern mode (single press) or enters preset manager (press and hold for 1 second).
  • Reset— Sets the number of steps in the sequence (1-8).
  • Step 2— Activates/deactivates step 2 or selects step 2 in menus. Press and hold to enter step settings.
  • Step 3— Activates/deactivates step 3 or selects step 3 in menus. Press and hold to enter step settings.
  • Gate Out— Gate/trigger output from active sequence steps. Can be configured as gate, trigger, half-gate, or merged gate.
  • Rate— Sets the frequency of the built-in clock (12-2400 BPM). When external clock is patched, allows division or multiplication of clock rate.
  • Reset Input— Reset/trigger input that resets the sequence to the first step.
  • Rand Play— Gradually mutates the sequence by randomly replacing steps. Turning clockwise increases probability; returning to 0 restores current panel s
  • Step 5— Activates/deactivates step 5 or selects step 5 in menus. Press and hold to enter step settings.
  • Step 5 CV— Sets the CV value for step 5.
  • Step 7— Activates/deactivates step 7 or selects step 7 in menus. Press and hold to enter step settings.
  • Transport— Play/pause the sequence. Held for 1 second enters global settings mode.
  • QUANT
  • Step 8 CV— Sets the CV value for step 8.
  • Step 6— Activates/deactivates step 6 or selects step 6 in menus. Press and hold to enter step settings.
  • CUSTOM
  • Step/Quant— Selects step mode (single press) or enters quantization menu (press and hold for 1 second).
  • Probability— Increases the probability of random setting inversions or adjusts the degree of randomization of the probability sequence in prob mode.
  • Range— Adjusts the amplitude of the CV output in quantized 1V increments (0-8V unipolar or ±5V bipolar).
  • PRESET
  • SLEW ON
  • Custom/Shift— Activates custom sequence programming or acts as shift control for secondary functions. Press and hold for 1 second.
  • Slew— Sets the global slew time from zero up to the length of a whole step for portamento/glissando effect.
  • Reset (knob)— Sets the number of steps in the sequence (1-8).
  • Step 8— Activates/deactivates step 8 or selects step 8 in menus. Press and hold to enter step settings.
