Hey all,
Does anyone have a non linear interpolation object that works something like "line" but does a nice ease-in ease-out acceleration curve? I'm finding line a little ugly for my Gem interpolation needs...
If one does not exist I'd appreciate any suggestions on how to approach this, I started messing with a sigmoid function but having trouble figuring out how to change the variables to have precise control of the in and out points... I'm finding a lot of references to the problem on google, but few (code) examples.
Thanks! Ben
Hi Ben, how about low-pass filtering?
good gain, Thomas

Hmmm,
I'm really not that familar with filtering algos, how can I use a signal as a pd control? (descrete messages). Anyone have an example?
fade~ sounds nice, same signal->control issue...
Thanks Ben

well you can use filtering not only for audio-signals but also for descrete messages "streams".
fade~ sounds nice, same signal->control issue...
there are several signal->control objects (like [env~], [snapshot~], avg~), but i guess, you know that...

Hi Ben, here's a small illustration how i'd employ low-pass filtering for smoothing of control messages.... this one uses the dsp, but if one has a message stream at constant intervals purely message-based filtering would be equally possible.
best greetings, Thomas
