I think we all use or have tried the software mentioned above. If you don't mind, I'd like to also introduce the idea that all the features that the different software have, doesn't help more than what's in your head.
I've been listening to some of the different songs lately and realizing that the accompanying music in many of the professional produced tracks is rather mediocre. So where is the advantage in having all the equipment, and talent and only producing an average backing for a vocal.
I' m not putting down the technology we have at hand but sometimes I get caught up in the technology instead of creating music. I then have to remind myself that if I will stop and let my right brain into the mix, I might make better music.
It might be interesting to make a backing track for any popular song with the simplest software and the more limited synths, add a quality vocal and ask 100 people what they thought of the cover version. I have a feeling that few would notice the difference in the cover backing as compared to the orginal song. Most will coment on the vocal not the backing.
BTW, I think BIAB,RB,RT's could produce something 95% or better as compared to most backing music for a lot of songs.
Just a thought
