Karl,
Thanks for asking. Let me step through just to simplify from my end.
Expand a new vocal track to show Take Lanes (1 Lane to start).
1) Record a take on a new track of lyric line 1 (first line on the lyric sheet). Stop. Disarm Lane 1.
2) Click the "+" on the Take Lane to create a new Lane.
3) Set the cursor about halfway back through the lyric Line 1 above.
4) With the first Lane unmuted, arm Lane 2 and click record to grab lyric line 2. Stop.
5) Now disarm Lane 2 and arm Lane 1 to record lyric line 3.
Record takes back forth like this (odd-numbered lyric lines on Lane 1 and even-numbered lyric lines on Lane 2).
So, inherently, what I'm trying to accomplish is limiting the number of Take Lanes to 2, but record multiple lyrical lines back and forth because they either overlap words or they're just too intense to get them all in a contiguous performance.
Hope this helps. Thanks!
