Logic Pro (X) Live Loops - queuing multiple cells: error


New Member
Hi, everyone. I'm learning how to use Live Loops. According to Apple's LP User Guide:

To queue multiple cells, select the cells (using Shift), then press Option-RETURN

However, this error msg always pops up: "Command not available because the selected cells are muted."

I don't have any muted cells. I also checked in the Key Command Assignments, and Option-RETURN is listed as the key sequence for "Queue Cell/Scene Playback."

Can some of you explain what's wrong? Thank you!
