I have randomly incoming values like for example these:

As soon as the value changes I want to blend, slide or fade to the new value while acceleratiing gradually and decelerating again to the end. the slide object is just decelerating. It starts too sudden. Does anybody have an idea?

I'm on Windows. I can't get msd (pmpd) running on my Machine, tried f0.smooth externals with the same results as slide.

I still haven't found a solution to tis:

smoothing-changing-values-inertia-slide-acceleration

but better ask (or serach for slide) in the main max-msp list.

this abstracion was found on the main list. there was an object that those

this internally. cant remember the name. mybe lp.scanmpf?

lp.scampf may be the object. Maybe I can patch something with that somehow but it's still not exactly what I thought of. I have to slide between values that don't change gradually but abrupt. Like smoothing a rectangular wave to something sine-like.

it will help to learn more about what your trying to accomplish.

sounds like youre trying to smooth input from a sensor.

it's not from a sensor it's user input. the user can choose the destination coordinates of different objects. the objects then move to these coordinates. this movement should accelerate and decelerate softly.

run a search on the main max list for "exponential"

You said the time between the inputs is unknown. However, once some object is clicked, you know how far it is distance-wise and you've probably got an idea how long the motion should take (which could be settable too).

I'd scale the distance value to something like 0-255 and use a lookup table for your scaling-per-datapoint function (how far it moves per time-step). Then you can tweak / draw the table just how you want it, or have multiple tables (like: further objects could behave differently, etc.) The cool functions talked about here can be used to fill the tables ... then you get to see what they look like graphically, too.
