  Automating values from custom points

  Posted by Jack Sewell on June 16, 2010 at 8:21 am

  I would like to modulate the values of an effect parameter from two custom points along the value spectrum.

  I was thinking about using a slider which was some how mapped with 0 being point A and it’s highest value being point B. This is the theory of course but I’ve no idea how to do this……

  I’ve tried lots of searching for this but can’t find any thing.

  Any ideas?!

  Many thanks as always! 🙂

  If you mean you want the value to be randomly changing with the number constantly staying within certain parameters, you can do it with wiggle. Say you want it to be between 25 and 75. Make it 50 and add a wiggle expression like wiggle(1,25) Every 1 second the value will shift +/- 25 from 50, meaning, it’s going down as far as 25 or as high as 75.
