Instruō

A clock generator and processor that converts a single internal or external clock into seven related clock pulse outputs, with spread-controlled division/multiplication, probabilistic masking for random or repeating phrasing, pulse width control, and live/lockable output states.892

Capabilities 4

Clock Dividerclock-divider
Seven outputs with spread-controlled division values down to sixty-fourth notes; individual outputs can be locked to specific division values.892
Clock Generatorclock-generator
Internal tap-tempo clock generator with smart tempo following; also accepts external clock input.892
Clock Multiplierclock-multiplier
Seven outputs with spread-controlled multiplication values up to octuple whole notes; individual outputs can be locked to specific multiplication values.892
Trigger Sourcetrigger-source
Each of seven outputs produces 5V clock pulse signals with programmable probability and pulse width.892

Jacks 11 (4 in / 7 out)

NameSignalVoltageDescription
Inputs (4)
CLKtriggerAccepts an external trigger/clock to set the module's tempo; glōc will smoothly follow tempo changes in the incoming signal.892
Probability CV Inputcv-5V to 5VBipolar CV input that sums with the Probability Knob position to modulate trigger probability across all outputs.892
RSTtriggerResets the internal division/multiplication counter and resets the 8-step repeating phrasing density pattern to step 1.892
Spread CV Inputcv-5V to 5VBipolar CV input that sums with the Spread Knob position to modulate the division/multiplication spread across all outputs.892
Outputs (7)
Clock Pulse Output 1clock≤5VDefault assignment: semiquaver triplets (sixteenth note triplets) at the base clock rate when Spread Knob is centred.892
Clock Pulse Output 2clock≤5VDefault assignment: semiquavers (sixteenth notes) at the base clock rate when Spread Knob is centred.892
Clock Pulse Output 3clock≤5VDefault assignment: quavers (eighth notes) at the base clock rate when Spread Knob is centred.892
Clock Pulse Output 4clock≤5VDefault assignment: crotchets (quarter notes) — the base clock — when Spread Knob is centred.892
Clock Pulse Output 5clock≤5VDefault assignment: minims (half notes) at the base clock rate when Spread Knob is centred.892
Clock Pulse Output 6clock≤5VDefault assignment: semibreves (whole notes) at the base clock rate when Spread Knob is centred.892
Clock Pulse Output 7clock≤5VDefault assignment: dotted semibreves (dotted whole notes) at the base clock rate when Spread Knob is centred.892

Parameters 5

NameTypeRangeBehavior
Mode ToggleswitchThree-position toggle selecting Lock (left), Regular (centre), and Live (right) programming modes for the clock outputs.892
Probability KnobknobAt centre (noon), all outputs fire at 100% probability. Turning left introduces coin-toss random logic reducing trigger probability; turning right introduces an 8-step density mask for repeating phrasing. Both extremes result in zero probability.892
Zones
Random Phrasing
Repeating Phrasing
  • Random Phrasing -100–0%Coin-toss logic reduces trigger probability randomly; fully left yields zero probability.892
  • Repeating Phrasing 0–100%8-step density mask creates repeating pulse/rest patterns; fully right yields zero probability.892
PWM KnobknobGlobally adjusts the pulse width of all seven clock outputs; turning anticlockwise decreases pulse width, turning clockwise increases it.892
Spread Knobknob892
Tap Tempo ButtonbuttonPressing twice calculates a new tempo; ignored when external clock is present. Also used in Lock mode to select/deselect output lock states, and to save configuration when held. LED colour indicates status: white blinks at steady tempo, amber during transition, off-white when external clock is present.892

Firmware history 1 version

VersionReleasedNotes
1.1.0Added Run/Stop behaviour as an alternative to Smart Tempo Following for better integration with external clock sources that stop and start. Also added the Assigning glōc Behaviour startup configuration feature.892
