This features is something that is just a Biiiiig time savers and you miss it when you don t find it on the new daw aka studio one (coming from Sonar)
Basically on each plugin window we have all tracks controls (mute , solo , automation arming ect ) , it s really a gain of time to be able to solo the tracks your tweaking without havin to go from the plugin to the tracks and go back on plugin ext back and forth ...
