Slowest slew with smoothest start/stop

i must be doing something dumb here, i have a patch with two offset signals mapped to midi knobs. when i turn the knobs, i want the offsets to change with the smoothest/slowest “ease in” and “ease out” possible. no matter which slew module i try, with whatever log/lin/exp settings, they still come to an immediate halt without easing to a stop first. i’m using this as a visual patch to move a dot around on a screen, i need it to slowly come to a stop when i turn the offset knob, but instead it suddenly stops dead in its tracks.

ive tried layering slews, using log slews like dintree, ive used nysthi SL uSlew module, how can i patch up this smoothed offset change to cover up my shaky performance fingers?

I vaguely recall someone describing a module that implements inertia, which I think is the concept you’re after. With inertia, there is resistance to get moving (or rise), then after incoming energy abates, it continues. With strictly inertia, it would just keep going, but in the real world, friction would cause it to fall (decay). This is all components of physical modelling, so perhaps there are some physical modelling modules that can be bent to the purpose.

lol! i figured it out. i was being dumb i guess, i kept setting the rise and fall curve shapes to be opposite eachother, i thought i was supposed to do that for some reason. this produced the desired result for me:

Some slew modules even offer symmetry between up and down, like the Sickozell.

I was immediately thinking about “that’s not possible” :reverse_button:
