PRV track panel color is different

How different is "way different"? The shade of PRV note colors will change with velocity and selection status, but it should still be in the same "family".

You have the Violins track selected as the active track, but not shown in the PRV. If you make Truepianos or Dim Pro Bass the active track, I think you will find that the shades are closer together - i.e. the notes of the active track will get darker. If you then select some notes in the active track as well, they should be pretty much the same as the color patch in the tracks pane.

The non-active tracks just get a lot lighter so that the active track stands out. Depending on the color, I agree it can be hard to see the relationship at a glance. I don't think there's any way to disable that, but you can disable the velocity-based shading by setting PRVColorizeVelocity=0 in Cakewalk.ini.

Cakewalk.ini will be in a path like:

C:\Users\Randy\AppData\Roaming\Cakewalk\SONAR X1 Producer\

Open it in Notepad, add PRVColorizeVelocity=0 under the [WinCake] section, save it, and restart SONAR. If there's no [WinCake] section, you can just add it.

You wouldn't notice a big difference. With PRVColorize enabled, a note with a velocity of 64 will match the color patch in the tracks pane. As the velocity decreases, the color becomes less saturated, and vice versa. It's fairly subtle in comparison to the active/non-active/selected changes.

Hard to be sure without seeing the full picture of what's active/selected and what's in the velocity pane. But based on the title of the image, I would have to say the second group of notes are just all at lower velocity than the first. That's what PRVColorizeVelocity does when enabled.

I usually see more variable continuously variable shading because I record everything in real time with natural velocity variation. But if you copy-pasted bits from different sources or manually entered notes at different times with different default velocities, you could get a group of notes that all have the same velocity, but lower then another group like that.
