The Orca operations Manual

The base operators are present in every version of Orca, no matter the platform:

• A add(a; b): Outputs sum of inputs.
• B bus(a; b): Outputs difference of inputs.
• C clock(rate; mod): Outputs modulo of frame.
• D delay(rate; mod): Bangs on modulo of frame.
• E east: Moves east, or bangs.
• F if(a; b): Bangs if inputs are equal.
• G gen(x, y; len): Writes cell at offset.
• H hold: Holds south operand.
• I incr(step; mod): Increments south operand.
• J jumper(val): Outputs north operand.
• K kat(len; in): Reads multiple variables.
• L less(a, b): Outputs smallest of inputs.
• M mul(a, b): Outputs product of inputs.
• N north: Moves north, or bangs.
• O read(x, y; read): Reads operand at offset.
• P push(len, key; in): Writes east operand.
• Q query(x, y; len): Reads cell at offset.
• R rand(a; b): Outputs random within inputs.
• S south: Moves south, or bangs.
• T track(key, len; in): Reads east operand.
• U uclid(step; max): Bangs on Euclidean rhythm.
• V var(write; read): Reads and writes variable.
• W west: Moves west, or bangs.
• X xwrite(x, y; in): Writes operand at offset.
• Y yumper(val): Outputs west operand.
• Z zlerp(rate; target): Scale south operand.
• * bang: Bangs neighboring cell.
• # comment: Holds a line.

The special operators make use of a platform's devices, here are the suggested special operators:

• $ self(cmd): Send a command to Orca, or load external file.
• : midi(ch oct note velocity*): Send a midi note.
• ! midi cc(ch knob val): Send a midi control change.
• ; pitch(oct note): Send pitch byte out.
• / byte(high low): Send a raw hexadecimal byte.
• = play(ch oct note velocity*): Play note with built-in synth.
