This is a serious omission from Sonar's automation functionality and it really causes me serious headaches.
When you are automating an effect in a ProChannel FX Chain for instance, the edit filter in the automation lane shows "Volume" instead of the name of the parameter you're automating. For God's sake, at least indicate what PLUG the automation lane is for. It's ridiculous! I have to remember, by heart, what parameter each lane is automating because Sonar doesn't tell me unless I actually navigate through the edit filter menu and see what plug is highlighted in bold.
This is all very well and good when you just have a couple of automation lanes, but try managing the automation of 10 parameters in a Guitar Rig effects chain. It's a nightmare! From Sonar's marketing blurb one would be led to believe that they are keen to develop a strong electronic music user base, but they are seriously lacking in the automation stakes.
