Re: [LAU] Touchpad to MIDI

Hi Will, as others have said this is very easy with a Pd patch. Use Pd from here, preferably over other distributions: http://msp.ucsd.edu/software.html Install the [hid] external using the "Find externals..." menu entry. Write a patch that loads this external library into pd, for example by creating an object [declare -lib hid] More help at the Pd mailing list at https://lists.puredata.info/pipermail/pd-list// Eventually you will have to change the permissions on the /dev/input/deviceXX file to have Pd read from it directly. Oh, I found it handy to disable the pointing device I am querying in Pd in the xserver so I don't click somewhere by accident and can still use another mouse to point and click: List all X input devices xinput --list filter for numeric ID of "USB Optical Mouse" xinput --list | grep "USB Optical Mouse" | cut -d "=" -f 2 | cut -f 1 get the number for the "Device Enabled" parameter of that mouse xinput --list-props `xinput --list | grep "USB Optical Mouse" | cut -d "=" -f 2 | cut -f 1` which in my case was 164. Then change its value to 0 or back to 1 xinput --set-prop `xinput --list | grep "USB Optical Mouse" | cut -d "=" -f 2 | cut -f 1` 164 0 xinput --set-prop `xinput --list | grep "USB Optical Mouse" | cut -d "=" -f 2 | cut -f 1` 164 1 best, P
