I'm trying out SOUNDFORGE Audio Cleaning Lab having never used previous versions. There are 8 tracks available on which to place audio and you can show and hide them with the buttons on the right side. But all tracks play whether they are visible or not. Is there a way to temporarily mute one or more tracks, or conversely just play one track (solo)? Sometime I want to check which audio is coming from which track. The only workaround I've found is to drag the object volume line (the grey one) down to 0, but that's kind of a pain. I'm using version 220.127.116.11.
