I had a morning wedding at Leu Gardens where I played electric violin to backing tracks. The main song request was A Thousand Years for the Processional and Recessional, but starting at different parts in the song. For this I made 2 separate tracks with different loops so I could anticipate longer or shorter needs. This is an example of why it's good to also be somewhat adequate at audio editing within a DAW! I use Logic Pro.
Violinist with a habit for anything creative.
