Thank you Splaat for the test and comments,

it seems you have a one way communication between Reaper and Lemur, Lemur doesn't seem to receive data from Reaper (track name, number, vu meters).

EDIT : i just test it at home and all is working as expect, can you verify the settings in the Lemur editor. In the Lemur tab the Local IP must be the same as Host IP in the Raper settings and Lemur IP must match the Device IP in Reaper. I hope it will solve the problem.

I don't know if it's related to your configuration or the ReaperOsc file, will investigate later today.
You can try to click on the Lemur button next to Reaper track follows in the device tab. I have to work much deeper this specific part of the layout.

In regard of the jog wheel, this is a know bug from Liine and it will be fixed in the next update.

For the return to 0 or center for volume or pan, there is nothing in Lemur by default perhaps can i try a script, i hope to find some time in the next days.
