@Bangflip Can you please post your noisy data so I can try a different smoothing algorithm on it? I'm porting something from the Arduino world for fun.

Yes, I deleted already my old data, but recorded this curve today, that you can use it. It's an strange curve.

I got this curve by send the pitchbend Data from Pure Data to Cubase and record as automation. All values linear via Mackie Mode. Then I switched Cubase to "Houston" Mode and recorded the the output of cubase with pd into the array. The result is always the same. I thought it has maybe to do with the 20 years old algorithm for my houston hardware. Because if I send the midi data via mackie mode to pd, it's much smoother, without these artefacts.

The curve you can see here is also a little bit different in what I described after starting this thread, because the artefacts are in the opposite direction. But it's clear to see with the eyes, how the curve should be. Would be cool, if you could also post, what you came up with. I am interested in the result.

@Bangflip I don't really understand this thread with respect to the hardware, but I was just curious if this thing I ported from the Arduino library "ResponsiveAnalogRead" (https://github.com/dxinteractive/ResponsiveAnalogRead) could remove all the negative first differences without making any assumptions about which way the signal should be heading (it can). I think it's just a self-adjusting version of the exponential moving average stuff that @whale-av posted. Put both files in the same directory and open "houstonData.pd" to run it.

Interesting, thank you! Will keep this for future needs.
