I upgraded to the newest Sonar Platinum, ver.23.3.0 Build 51, and Track List pane in Piano Roll view has changed almost beyond recognition: [image]c:\tmp\track list.jpg[/image]
There are no padlock icons, also in addition to midi tracks audio tracks have appeared due to some reason.
How do I disable a track then? Maybe I'm missing something really simple but Help has not given me any clue...

Hi. Does this help?

All the best.

Thank you, downloading the new documentation now, will see if it clarifies things.

From your OP this is the one you probably need.

Click the filter button next to the midi tracks you want to see in the PRV.
Then click the global filter button on the PRV header. This will show you only the tracks you choose with the filter selection.
 
As far as locks... you don't need them anymore. there is a global lock feature now.
At first I was a little hesitant about these new changes. I had a WFT is this moment myself.
But after toying with it a few days I realized these changes are amazing and a much needed improvement.
 
 

Almost perfect. 
The only thing I miss is that the track selection is not saved with the preset/project. E.g. I filter 3 tracks in, but only the selected one(s) are visible. I select all 3 and save the filter preset and project. After I reopen it, only one track out of three is selected, so in order to make all 3 visible I have to manually select all 3 again.

"Persistence of View" (Thanks Crag Anderton for the catch phrase)
is, in my opinion, is the most problematic work flow slowdown of any in Sonar.
