Remarks
• The state of the variable is saved not only with the patch (or multi or host chunk), but also when
a script is saved as a KONTAKT preset (.nkp file).
• The state of the variables is read at the end of the init callback. To load a stored value manually
within the init callback, use 
read_persistent_var()
.
• You can also use the 
on persistence
callback for retrieving the values of persistent varia-
bles
• When replacing script code by copy and replacing the text, the values of persistent variables
are also retained.
• Sometimes, when working on more complex scripts, you'll want to "flush" the variables by re-
setting the script. You can do this by applying an empty script in the respective slot.
Examples
on init
declare ui_knob $Preset (1,10,1)
make_persistent ($Preset)
end on
User interface elements, such as knobs, should usually retain their value when reloading the in-
strument
