A quick tip I found out the other day (that speeds up things for me) is to hold the 'SEL' button of a track and get the levels for that track (Level, Panning, Delay and Reverb)
You can use the C1-C4 encoders to change the values quickly.
No need to assign them to one of the 3 track knobs (only if you want to automate these values)
