funneling in toward a target number

January 17, 2009 | 5:47 am

hi everybody,
there must be a simple way to do this (right?). I feel like I’ve done
it the hard way, and I’d like some feedback–if anybody can tell me
about a simpler method I’ve overlooked. Or other suggestions.

I’d like to have a range of numbers that funnels down toward a target
number. (My idea is that I’ll use this to control the frequency of a
bunch of partials. These upper partials of a given fundamental will
scramble around an increasingly circumscribed range, each eventually
landing on a different target frequency.)

I’m using two tables and counting through them, getting the Y values,
and plugging them into the range inlet of drunk objects. (I’ll scale
all this later, right now I just used values btw. 0-127). One table
is used to define the upper limit, the other for the lower limit.

Maybe it’s time to figure out Markov chains? Or is there another way?
here’s the patch (Max 5)…

best,
Sam

Hi Sam,

This looks like a reasonable enough way with stock Max objects. Here’s a slightly modified version of your patch (consolidated metros, etc.).

best,
Zachary

Markov chains are Stateless by nature.

Though there is a perceptual change in time, your math needs to be
stateless I would presume.

I’m unsure how to use your binary attachment below, seems to be a MIME
attachment problem.

thanks Zachary

I learned a lot going through your version of that patch.

best,
Sam
