i considered script self-modification but you get into messy territory, and you can do almost everything you’re probably thinking of with variables and presets.
CV.OFF is cv offset per output.
CV.OFF 1 V 1
cv.offset and cv values get added together. for easy transposition. cv.offset can be negative, but the outputs are 0-10v clamped.
in your example, if you wanted random offset per cv, you have many ways of doing this… the easiest would be:
trig 8: X RAND 2
trig 1: CV 1 V ADD 1 X
trig 2: CV 1 V ADD 2 X
etc… X is a temp var.
or, there are tons of ways to do this, really.
