CHAPTER 21. LIVE MIDI EFFECT REFERENCE 289

21.5 Random

The Random Effect.

Random adds an element of the unknown to the otherwise commonplace pitch parameter.

The Chance control denes the likelihood that an incoming note's pitch will be changed by a

random value. You can think of it as being something like a dry/wet control for randomness.

The random value that determines the pitch change is created by two variables: The Choices

control denes the number of different random notes possible, from a range of 1 to 24; the

Scale control value is multiplied by the Choices control value, and the result dictates the

pitches that random notes are allowed to have relative to that of the incoming note.

For example, if you play the note C3 with Chance set to 50 percent, Choices set to 1 and

Scale set to 12, half of the resulting notes will play at C3 and half will play at C4. But with

Chance set to 50 percent, Choices set to 12 and Scale set to 1, half of the resulting notes

will play at C3 and half will play at one of any semitone that is between C#3 and C4.

These examples assume that the Sign buttons are set to Add and the Mode button is

set to Rnd. The Sign controls decide whether the random alteration adds to the original

note's pitch, subtracts from it, or does a little of both. The LEDs above the Sign controls

give you a visual idea of how output pitch compares with that of the original.

The Mode button determines whether the alteration will be random or, when set to Alt,

will cycle between the allowed output notes in a xed order (sometimes known as cycle

round-robin). The Chance control behaves a bit differently in Alt mode - at 100 percent,

the next output note will always be the next note in the series. At 0 percent, the next output

note will always be the incoming note.

For example, with Chance set to 100 percent, Choices set to 12 and Scale set to 1, playing

1 2 ... 286 287 288 289 290 291 292 293 294 295 296 ... 409 410
