You would do well to learn Realband as your DAW and see what you may need that it doesn't do.

It does some things no other DAW can do, and can't do some other things. They all have their pluses and minuses.
You'll already have it and will likely find it meets your needs for quite a while.

Question 2- How many instruments do you desire to record at a time?
What is your budget?
How will it connect? Do you have a desktop with a PCI slot, or a laptop that will need something that runs thru USB?

I do not work here, but the benefits are still awesome
