This is my first time doing a ‘multi-track’ video in a very long time. Irish jigs, melody on piano accordion with piano accompaniment.
In this case I just recorded the melodies first, hoping I could bring across a strong enough rhythm in my playing to make recording the accompaniment relatively easy - then just listened to the video on another device while recording the accompaniment track. With a few places where it threatens to jump the rails, I think it works OK.
