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:

Interference

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 modulator, 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 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.
  • 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, marking the beginning of the sequence.

Symmetry

Symmetry is a dual quantizer / scale arpeggiator module based on symmetric distribution of pitch. It has two separate sections sharing a common scale with 10 scale types, and pitch selection and randomization options, providing a vast range of scales. Use it as a quantizer, an arpeggiator, a stepped random voltage generator, or an interval generator.

Stoev Symmetry Eurorack module

Main controls

TYPE knob and CV input – set the type of scale*.
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 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 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. Orange color indicates that there are no more expansions or contractions available for the scale. When 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 inputs and outputs

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