5.5. Randomness/Probability
The Randomness and Probability encoders enable you to add an element of unpredictability
to your sequences and drum patterns.
To summarize how the Randomness and Probability parameters interact:
• The Randomness value determines how
much
Randomness will occur;
• The Probability value determines how
often
the Randomness will occur.
You can specify how much these features will affect the sequencers. As their levels are
increased, the following aspects of the sequenced notes can be affected:
• The playback order
• The rhythmic pattern (Steps on/off)
• The velocity (dynamics)
• The gate time
The pitches of the melodic sequencer notes will not change (though their
), so the sequence will stay within the chord structure you have
defined. But the rhythms, playback order, dynamics and length of the notes will become
increasingly disturbed as you increase these parameter values.
In a Drum pattern, only the rhythm, dynamics and length of the events will be affected.
♪
: The Randomness and Probability parameters will act only upon drum tracks that already contain
active steps. They will not generate new steps within an empty drum track. For example, if there are
no events on the snare track there will continue to be no snare events regardless of the Randomness/
Probability values.
5.5.1. Randomness
The Randomness encoder has a range of 0-100%, with 0% having no effect on the music.
But at 100% the rhythm, velocity and gate times of all three sequencers will be entirely
random, within the constraints of the Probability setting. The pitches of SEQ1 and SEQ2 will
be selected at random also within the pitches of their current sequences.
♪
: The MIDI Control Center has a Global parameter for SEQ1 and SEQ2 that will restrict the effect of
the Randomness parameter to the octave ranges of the notes. See the
section of the
chapter for more information.
The Randomness encoder is touch-sensitive, so you can check its setting without editing the
value by touching the encoder.
