  Parameters for Scale question Again in conjunction with sound keys,

  Posted by Richard Altman on May 22, 2012 at 1:19 am

  so i have a png/jpeg that i need to scale up to around 228% to be a decent viewable size,
  using sound keys i’d like to fluctuate (to the beat obviously) between 270 and 444% if the triggerLevel gets beyond 1
  

  from my understanding, if the soundkey value gets over 1 wouldn’t the scale based on the condition fluctuate between these two numbers, either exclusively or inclusively between their values?

  thanks in advance, apologies for the ignorance, and as usual sincere appreciation and respect

  ok, so i just went into the default expression produced by pickwipping the scale to the soundkey parameter and added [temp+100, temp+100] works well enough for me [simple minds, pleasure etc]

  nonetheless, an explanation of the trigger question if you have time would be appreciated, if not i’m sure eventually [cryogenics] i’ll figure it out

  Try changing the last line to this:

  if (sk1 > triggerLevel) [270,270] else [444,444]
