I use Vegas to make music , i use it as others might use a sequencer.
I create all kinds of music but mostly electronic stuff and i have been wanting midi /rewire and all the stuff that has been mentioned in the past here on the board.
I have officially given up on vegas supplying the needed functions for someone like me that´s creating music in Veg rather then just recording.
I do however love using it for just recording and editing so i´ll keep on using it for just that

When creating tunes in Vegas i find very frustrating to move big sections and try things out in Vegas as its just not very fluid in that respect.
So i present to you the ultimate workflow that i just recently stumbled upon.

What i do is take the song im working on (when i have the basics down and have done all my recordings) and i make regions for 1 bar or whatever you might want to use and then i set the tracks up in sections (ambience, bass , drums etc ) and render each section with included markers/regions.

Then i open the tracks up in SForge and extract regions to seperate folders for each selection of tracks.
Then i open up Ableton Live and set the regions up as clips in the same sequence as the song and Voila...total freedom !!!!

Now you have the tune in its original form but are free to try whatever mix of sections you might think of.
Now you are free at last to do MIDI / rewire /arrangements and LIVE arrangements .

I mention this because it takes me 10 minutes to set up a tune from vegas into Live ....Awesome! ...Finally !
