LATOOCARFIAN(outsk, dur, AMP[, A, B, C, D, X, Y, PAN])
CAPITALIZED parameters are pfield-enabled for table or dynamic control (see the maketable or makeconnection scorefile commands). Parameters after the [bracket] are optional and default to 0 unless otherwise noted.
| Param Field | Parameter | Units | Dynamic | Optional | Notes |
|---|---|---|---|---|---|
| p0 | output start time | - | no | no | |
| p1 | duration | - | no | no | |
| p2 | amplitude multiplier | - | yes | no | |
| p3 | parameter a | - | yes | yes | default: 2.871 |
| p4 | parameter b | - | yes | yes | default: 2.75 |
| p5 | parameter c | - | yes | yes | default: 1 |
| p6 | parameter d | - | yes | yes | default: 0.75 |
| p7 | seed x | - | yes | yes | default: 0.5 |
| p8 | seed y | - | yes | yes | default: 0.5 |
| p9 | pan | in percent-to-left format | yes | yes | default: .5 |
Parameters labled as Dynamic can receive dynamic updates from a table or real-time control source.
Any values for p3-p8 are legal. Pickover recommends values for a and b between -3 and 3, and p4 and p5 between 0.5 and 1.5. Depending on the values provided, results may be chaotic noise, pitch, or silence.

LATOOCARFIAN is based on a function given in Clifford Pickover’s book Chaos in Wonderland.
The Latoocarfian chaotic function was described by Clifford Pickover in his book Chaos in Wonderland. Any values for p3-p8 are legal, but not all values will produce sonic results. Try values of -3 to 3 for p3 and p4, and values of 0.5 to 1.5 for p4 and p5.
