So I have two video clips. Lumix and Gopro

I have two audio sources I want to use. The Lumix recorded with a shotgun mic and additionally an ZoomH6 recording.

I want to be able to balance the Lumix and ZoomH6 independently. Is there an easy way to keep the audio apart and sync them in the timeline?

I have already used the multicam settings to REMOVE audio from the gopro...

I tried audio sync a couple diff. ways but end up with a solid single multi / sync clip. I think best case I have the second (zoom) audio sync'd but below the main video with the lumix audio. If that makes sense?

Finding multicam and multi audio tutorials has proven difficult.

TIA! Also my first stab at color correcting manually with color wheel :) not TOOO shabby I think.

You must properly prep the material prior to multicam sync. Procedure in this tutorial by Sam Mestman:

If it doesn't sync properly -- IOW enabling angle editor via SHIFT+CMD+7 doesn't show synced A/V -- that is a sync issue not a failure to balance each channel.

A sync failure can be from several causes. One cause is poor audio quality or short clips having insufficient data to analyze the waveform. Clips shorter than about 30 sec are more likely to have sync failures. If the cameras were widely separated during recording, sync is more likely to fail since the audio is different on each camera.

I will check that out right away, I followed the last video and took my 8 gopro vids (it splits them automatically) and syncd with my one lumix vid... It's off about 4/5 frames im trying to manually move them all now... reallllly super annoying

This video look suuuppperr helpful thank you!

Now to just figure out the sync concern! Seems like its good between Lumix and the H6 audio, but the go pro falls behind...should all be 24p

You can selectively adjust and attempt re-sync of a single camera or audio clip within an existing multicam clip: support.apple.com/kb/ph12661?locale=en_US

Whats odd is that after just starting fresh again with a new multicam clip; the audio is ALL sync'd only the gopro video falls shortly behind. Super easy to spot with fine guitar movements. I will read through this link thank you again!
