Melodi

Omnitone

Semi-random melody sequencer/generator that outputs gate and 1V/oct pitch. Eight tunable parameters set the mood of the generated sequence.255

Capabilities 1

Semi-Random Sequencersemi-random-sequencer
Generates semi-random melodic sequences with 8 tunable parameters controlling skip probability, gate length, tie probability, pitch trend, scale quantization, octave range, sequence length, and internal clock speed.255

Jacks 6 — 3 in / 3 out

NameSignalVoltageDescription
Inputs (3)
CLOCK INclock—Connect external clock signal.255
CYCLE TRIGGER INtrigger—Jack trigger to restart the sequence at the beginning.255
TRIGGER INtrigger—Accepts a trigger to prompt Melodi to generate a new sequence.255
Outputs (3)
CLOCK OUTclock—Outputs clock signal.255
GATE OUTgate—Outputs the gate of the notes in the sequence.255
PITCH OUTcv—Outputs the pitch (in V/OCT) of the sequence.255

Parameters 12

NameTypeRangeBehavior
CLOCK SELECTswitch—Switch selects internal or external clock. Up = internal clock; down = external clock input.255
CYCLE TRIGGERbutton—Button (and corresponding jack) trigger the sequence to restart at the beginning.255
LENGTHknob1steps – 16stepsSelects the number of notes to play in a sequence (from 1–16, or infinitely generating at the max position).255
NEWbutton—Prompts Melodi to generate a new sequence.255
ON/OFFswitch—Determines if the sequence will loop continuously or require retriggering to play again.255
PLUCKknob0% – 100%Sets the length of the gate, from short plucks to gliding between notes (portamento).255
RANGEknob1octave – 4octaveSets the range of notes from 1 to 4 octaves (unquantized).255
SCALEmenu_setting—Selects the quantization of the notes used in the sequence: perfect notes, pentatonic scale, diatonic scale, chromatic scale, or completely unquantized.255
SKIPknob0% – 100%Sets the probability that a note will be skipped in a sequence.255
SPEEDknob20BPM – 2000BPMSets the tempo of the internal clock, between 20 and 2000 BPM. Only active when the CLOCK SELECT switch is set to internal.255
TIEknob0% – 100%Sets the probability that a note gets tied to the next, effectively making the note last two clock cycles.255
TRENDknob0% – 100%Sets whether the sequence trends upwards or downwards in pitch.255
