This may very well be user error, I can't suss it out. LAP 6.1.1, OS9. Every once in a while, when I press play, Logic will only play the track that is selected in the Arrange window, as if it were solo'd somehow. If I select a different track, it will switch to that one. I am not in 's' key solo mode; there are no muted tracks or objects; and there are no solo or mute buttons active on the channel strips. The only way out of this is to quit and restart Logic, which makes me think it's a bug; however, I figured I'd ask first to be sure I'm not missing something. Thanks for your help, u b i k
