: I just upgraded Studio One Professional from 3.5 to 4.6. All is well except for a problem with the track mute and solo functions. They light up when engaged, but don’t work. When a track is soloed, it lights up, but all tracks continue to play, even tho’ their mute buttons are on. Also, when a track is muted, it lights up and the volume drops slightly, but you can still hear it. Is there a control somewhere for these functions? This was no problem with version 3.5, or those before it. I'm using a Windows based Creation Station from Sweetwater, with the 192 Mobile interface.
