Omnitone / omnitone/rhythmi

Rhythmi

Rhythmi is a Eurorack drum sequencer that allows you to dial in your groove, and explore it by evolving the pattern and modulating the energy. It allows for rhythmic inspiration and creativity without the burden of step programming. [28]

Capabilities

  • CV Input cv-input
  • Clock Source clock-source
    Generates internal clock when no external clock is patched; can also divide/multiply an external clock by up to 10x. [28]
  • Drum Sequencer drum-sequencer

Inputs (2)

NameSignalVoltageDescription
In clock — External clock input. [28]
Reset mixed — Resets the module to the beginning of the loop. [28]

Outputs (7)

NameSignalVoltageDescription
CRASH trigger — [28]
HI-HAT mixed — Outputs gates and triggers depending on whether an open hi hat or closed hi hat is played. [28]
KICK trigger — [28]
Out clock — Outputs the clock used by the module, including the clock dividing/multiplying and the swing. [28]
SNARE trigger — [28]
TOM trigger — [28]
TOM CV cv — Outputs the pitch of the tom with v/oct tracking, quantized to a minor pentatonic scale. [28]

Parameters (11)

NameTypeRangeMin FWBehavior
Base Pattern button — — Determines where in the loop specific hits start playing as density is increased. There are 5 different base patterns. Changed by long pressing the encoder knob. [28]
CHH menu_setting — — Closed hi hat voice control. [28]
Density menu_setting — — Sets the total amount of hits that occur for a particular piece given the syncopation setting. [28]
Energy menu_setting — — Macro control over kick, snare and tom densities and syncos. As energy increases, densities rise until the cursor turns red, at which point crash and kick are triggered at the beginning of each loop. Further increase biases synco towards 50-50. [28]
Evolve menu_setting — — Turn the encoder to explore variations of the drum pattern. Turning counter-clockwise returns to the root rhythm. Short pressing randomizes variations. CV can also randomize variations when enabled by holding the speed encoder and pressing the evolve encoder; CV randomization triggers when evolve value exceeds 75%. [28]
Length menu_setting 2clock pulses – 32clock pulses — Sets the length of the loop from 2 to 32 clock pulses, displayed on the vertical LED strip in groups of 8. [28]
OHH menu_setting — — Open hi hat voice control. [28]
Speed menu_setting — — When no external clock is patched in, sets the internal clock speed. When an external clock is patched in, acts as a clock divider/multiplier up to 10x. [28]
Swing menu_setting 50% – 90% — Sets the placement of every second clock pulse from 50% (no swing) to 90% at maximum. [28]
Synco menu_setting — — Sets the approximate ratio of non-syncopated and syncopated hits for a particular drum piece. [28]
Tom Amount menu_setting — — Sets the number of available pitches for the tom to play, akin to how many different tom drums a drummer has available. [28]
