Changes Script Overview

Controlled change in music is important for listener interest. Changes may take many forms, such as varying the tempo, loudness or velocity, melody, chords, rhythm, instruments, pan positions, or effects like Arpeggio or Note Bend.

Changes Scripts allow you to control all these and much more, including features that are not available from the standard Voice Setup or Percussion Setup controls.

You can control both the timing and the nature of the changes using simple constants, or with mathematical expressions that may include random values, current computer keyboard states, input or buffered notes, or oscillators.

Scripts allow standard programming structures like nested loops and conditional (IF-ELSE) statements.

Each voice (including Percussion) may have a separate Changes script, but any script may control any voice... and can even disable and enable other scripts. All scripts appear to run concurrently, forming a simple 9-thread multi-tasking system.

Note that Changes scripts affect the working values of variables, invisibly changing them from the visible initial values that were set via the normal controls. Those same initial values will be used every time a performance is started.

Note that the Changes On/Off button must be active in a voice for its script to run.
