I've used Audacity for a few thinks and I like it. However, I'm not trying to produce a song to play back or distribute (yet). I'm just trying to notate what I improvise when I'm following a leadsheet or play along with an MP3. This allows me to work up better, more consistent phrases and leads to use as a foundation at band rehearsals and performances. Plus, my hand notation is horrible and even I can't read what I've scrawled on a leadsheet. If I don't write it down or record it, I can't remember what I did later - for a repeat during the same song or another day. I'm hoping that the end result of my efforts with BIAB is a base library of fills and solos that I can re-use or enhance whenever we perform the song again, and maybe something my composer buddy can build on later when scoring these songs for horns or orchestra, if he hasn't done that yet.
