Operators

• A add(a b): Outputs sum of inputs.
• B bounce(rate mod): Outputs values between inputs.
• C clock(rate mod): Outputs modulo of frame.
• D delay(rate mod): Bangs on modulo of frame.
• E east: Moves eastward, or bangs.
• F if(a b): Bangs if inputs are equal.
• G generator(x y len): Writes operands with offset.
• H halt: Halts southward operand.
• I increment(step mod): Increments southward operand.
• J jumper(val): Outputs northward operand.
• K konkat(len): Reads multiple variables.
• L loop(step len val): Moves eastward operands.
• M multiply(a b): Outputs product of inputs.
• N north: Moves Northward, or bangs.
• O read(x y read): Reads operand with offset.
• P push(len key val): Writes eastward operand.
• Q query(x y len): Reads operands with offset.
• R random(min max): Outputs random value.
• S south: Moves southward, or bangs.
• T track(key len val): Reads eastward operand.
• U uclid(step max): Bangs on Euclidean rhythm.
• V variable(write read): Reads and writes variable.
• W west: Moves westward, or bangs.
• X write(x y val): Writes operand with offset.
• Y jymper(val): Outputs westward operand.
• Z lerp(rate target): Transitions operand to input.
• * bang: Bangs neighboring operands.
• # comment: Halts a line.

IO / Norns operators

• ' timber engine(sample octave note level position): Triggers sample player.
• " timber param(sample param value): Sets timber param on bang.
• / softcut(playhead rec play level rate position)
• \ softcut param(playhead param value): Sets softcut param on bang
• > g.write(x y value): Sets grid led on bang.
• < g.read(x y): Reads specific coordinates. If value > 6 outputs bang.
• : midi(channel octave note velocity length): Sends a MIDI note.
• % mono(channel octave note velocity length): Sends monophonic MIDI note.
• & midi in(channel): Outputs midi note
• ^ cc in(cc): Outputs midi cc value
• ! cc(channel knob value): Sends MIDI control change.
• = OSC (path;x;y..): Locks each consecutive eastwardly ports. ; is delimeter for values
• $ r.note(mode scale): Outputs random note within scale.
• ? levels(param value): Sets selected volume level on bang
