You record straight into edison, assuming you have your audio input set to that mixer track and the mic plugged in !! then you sing and record, and then you can use the editor (edison) to normalize, trim or whatever needed to that audio file you have recorded. Edison is a wave editing plugin and is pretty neat, though probably much more simple that other wave editors out there these days. The way I record is by going to the mixer, pick a track and add edison as a plugin to that track. I also use it to record some outdoor sounds (birds etc) which I later edited down to individual files.
I do however use FL 12 and I do record my own vocals for my tracks. Thinking about ditching Pro Tools 9(Don't want to spend $$ to upgrade) and making FL my main DAW.Truth is I can't answer your question as I have no experience with Pro tools or cubase. Is it up there with Pro Tools, Cubase, Studio One Etc when it comes to tracking vocals or is it still better to be used for beat production. Since they came out with a brand new version of FL Studio, I was wondering were there any changes which made FL Studio more accessible for Vocal Recordings/Mixing.
