Using HID with a PS3 controller

rjohn45

Hi everyone,

Hope you're all doing well. I'm fairly new to Pure Data and I've come up against a problem that I can't seem to get by. I've connected a PS3 controller via the hid object and I'm trying to make a series of beats in a PD patch that I control with the controller. Assigning parts to the buttons is no problem really but I'm finding it very difficult to use the joysticks correctly. I'm attempting to use them to control volume, and when I move them they do adjust via the slider I have them connected to via a send object, but when I let go of the joystick, because its spring operated, it reverts back to the middle and the volume stays at 50, rather than remaining where I had moved it to. Does anyone know of a way to fix this so that the spring mechanism of the controller is mitigated in regards to whats happening in the patch? Thanks a mill, cheers!

@rjohn45 The sort of challenge I like.
I have put a "sensitivity" fader.
Picking up the volume again where it was set the last time is easy with [moses].
But the joystick takes time to flick back to 50.......and at the same time you do not want to simply ignore messages that decrease the volume intentionally.

You will have to set the sensitivity fader so that intentional messages work but letting go of the joystick does not flick the volume down a little bit (and then store your patch so that it is remembered).
That will make the volume just very slightly unresponsive...... a very small delay but hopefully unnoticeable. I can't see how to avoid that.

At the top left of the patch is a testing setup for me as I do not have a joystick..... you can delete that bit and put your joystick data in where [inlet volume] is.
Here it is......... mitigate_volume.pd

It should ignore leftward movement of the joystick..... everything happens on the right hand side.
An alternative would be to use leftwards as "turn down" and rightwards as "turn up"...... and a much slower change in the volume..... possible of course..... a sort of "nudge up" "nudge down"...........
