i have question. if i play ssl, but next song i want chang play vinyl. so, i want take out ssl software or have any convenient
resource can do ?

you dont need to take out SSL, just switch your mixer channel to phono entry...

also you might want to unload the deck in ssl on the turntable you're playing the real vinyl on so you don't get weird output out of ssl. hit alt (option)-shift-left or right arrow (depending on the deck) to unload the track.
