Stoev modules for VCV Rack

Stoev is a collection of virtual Eurorack modules. Each module is designed like a physical device, and as part of a composition/performance system. Currently released modules include:

Interference is a poly rhythm generator module based on wave motion. It can generate up to 8 separate but interrelated rhythms, providing a wide range of rhythmic patterns – from very simple to very complex. Use it as a trigger sequencer, a clock generator, a clock divider, or all at once. Even try it as a sound source.

Stoev Interference Eurorack module

Main controls

PLAY button and CV input – start/stop the sequence.
Tempo knob and TEMPO CV input – set the speed of the sequence in BPM.
EXT CV input – an external clock input. Sets the speed of the sequence, bypassing the internal tempo.
Tempo indicator – flashes at the current tempo.
RESET button and CV input – restart the sequence.

A, B, C, and D

Four separate rhythm generators. Each has a:

  • Ratio knob and CV input – set the ratio of the rhythm generator to the tempo. The CV input expects 0.5 V/division, offset by the knob.
  • On/off button – turns the rhythm generator on/off.
  • Trigger output – a separate output for the rhythm generator.

Trigger outputs

CLOCK – outputs a steady rhythm at the current tempo.
R – the primary sequence. Outputs a rhythm generated by the currently active rhythm generators.
R’ – the secondary sequence. Outputs a rhythm complementary to R.
ACCENT – outputs a steady rhythm at each repetition of R (and R’), marking the beginning of the sequence.


When only two rhythm generators are active R and R’ are the same.

Symmetry is a dual quantizer/arpeggiator module based on symmetric distribution of pitch. It has 10 different scale types and pitch selection or randomization options providing a vast range of scales*. Use it as a quantizer, an arpeggiator, an interval generator, or a stepped random voltage generator. Even try it as a digital noise source.

Stoev Symmetry Eurorack module

Main controls

TYPE knob and CV input – set the type of scale*. The CV input expects 1 V/type, offset by the knob.
Pitch-unit buttons – set the pitches in the scale*. Starting with a root at the 12 o’clock position each consecutive button in clockwise direction is one semitone above the previous one.
RANDOM button and RAND CV input – generate new pitches in the scale.
AXIS knob and CV input – transpose the current scale in steps of one semitone. Range of +/-12 semitones.
INTERVAL knob and CV input – offset the CV output of section B in steps of one semitone. Range of +/-12 semitones.
ƒ button – changes the function of < and > buttons.
< and > buttons – when the light of the ƒ button is off, < and > buttons set the tonal expansion or contraction of the scale*. On each button press the scale is expanded or contracted one more time. Yellow color indicates that there are no more expansions or contractions available for the current scale. When the ƒ button is lit in red, < and > buttons set the arpeggiator mode. Green color indicates the currently active mode: > – up, < – down, <> – up/down, off – random.

A and B

Two separate sections sharing a common scale. Each section has a:

  • CV input – the main input. Connect a signal for quantization here.
  • TRIG input – when Symmetry is used as a quantizer and the TRIG input is connected, the input signal is quantized only when a trigger/gate is received. If the TRIG input is not connected, the input signal is quantized continuously. When Symmetry is used as an arpeggiator, the next pitch is output only when a trigger/gate is received.
  • CV output – the main output.
  • TRIG output – when Symmetry is used as a quantizer, outputs a trigger each time the input signal is quantized to a new scale degree. When Symmetry is used as an arpeggiator, outputs a trigger each time a trigger/gate is received at the TRIG input.


When the inputs of section B are not connected, its outputs mirror the outputs of section A.
