I'm new here...

I'm an amateur musician (mostly guitar but some keyboards too).

I've been using multitracks mainly for:

- hearing the part I'm learning on it's own
- making a version of the song with the part I'm learning/playing missing
- so when I play with the song it's only my guitar (or keyboard) I hear
- sometimes I make Rocksmith custom songs the same way
--- with all the tracks included in the mix except the guitar part

Sometimes it's fun to just dig around through the multitracks to hear new bits of the song, or make alternate mixes.

Cheers,
theseeker
