Hi everyone ! First post here, thanks in advance for your replies.

I'm trying to code an automatic slider in PD to mimic the behaviour of the pitch bend slider on the Arturia Microfreak synthesizer. The slider has a range that goes from -1 to 1.
I want it to output the right float number when I touch it, but to reset to a default state (which would be in the middle, so at 0) when I release it. A bit like the inverse of a [change] objecté So when not in use, the slider always comes back at the default state.

Can someone help me with this please ?

Thank you so much !

Hi,
with this [line] it goes back to 0 in 500ms:

Thanks !

That sort of does it. I'd like for it to be a bit more stable, as I'll use it for a pitch bend. If you have any other input on that, I'd really appreciate it.

@vfsonore How about this? Uses [iemguts/receivecanvas] to detect mouseup and reset the slider.
bender.pd

Edit: Had a spare moment to fix it afterall, think I sorted it all out.

Hey @oid, thanks a lot ! i'm not able to install iemguts at the moment, and this patch is to use on a hardware instrument on a Bela board with a Trill sensor, so I'd have to compile iemguts on Bela and it's not up to my level yet. I'll study your patch and see what works for me, thanks !

@vfsonore I don't think iemguts would work with Trill anyways but Trill looks to have pressure sensitivity, so all you need to do is replace [receivecanvase] and [route mouseup] with some logic to read zero pressure, so pressure data into a [change] and than a [sel 0] should do it. You can dump the [set $1( message completely and replace the slider with your position data.

Edit: and you would probably want to read the initial position value as zero and subtract that from all subsequent position data so you do not have to worry about hitting dead center to avoid a sudden jump.
