tip: msp objects for smooth jitter parameter changes


    Mar 03 2012 | 12:18 pm
    Hello,
    Yesterday I realized how easy it is to use msp objects with jitter and I thought I'd share this for those who did not realize this yet. It might be covered already in tutorials or jitter recipes, I don't know.
    did you know? :-)
    Let's say you would like a smooth parameter change from 0. to 1. in 2 seconds You need to sync this to the render metro to make it smooth
    If you use the [line] object it is hard to sync this properly to the metro, if you use [bline] you will get in trouble if your framerate is not constant. You could make your own synced line version using cpu clock, but it is much easier to use an [adsr~] object with a [snapshot~] below it connected to the render metro bang, you can get that transition that I mentioned with [adsr~ 2000. 0. 1. 0.]
    you could also use phasor~, cycle~, line~, function + line~ and what else you can think of
    Happy patching!

      Nice tip, I like the new anim objects for 3d parameter changes.

      yes, they are fun too and with a bit of routing you can add render metro synced spring behavior to other parameter changes as well

      so is there a corollary to this story? jitter objects good for MSP.....?

      I don't know about MSP, but Jitter matrices are very useful in Max. I've used them to store and recall entire states for my Launchpad. They can interpolate between complex data sets with ease, and generate easily navigated and stored data states. They translate easily into and out of list form too, so you can use them to do list processing. I'm currently building a patch that addresses a 64 voice poly~ via an 8x8 Jitter matrix. If what you're dong is using large data sets, then Jitter is the place to be, in my opinion.

      and useful thoughts good for emtpy brains.

      @Liam: oh, yes, that is certainly the case, e.g. the spectral work of Jean Francois Charles or Alex Harker's timestretcher built in jitter (work in progress )

      cool. guess I should start hacking into those jitter tutorials then. MAX just gets better and better the more you know :)
      I was reading about cell automata for composition recently too which would involve jitter bits and bobs but that is very much at the end of my massive list of things to do.

      @Liam, maybe you'll like what Luke did with conway's game of life http://vimeo.com/26537306
