Now that we've answered your question, tell us what you're trying to do. It sounds like you want to get a set up for live performance, is that right? If so, there's many threads here about that. Also what type of player are you and what style of music are you interested in?
Nothing wrong with using Biab to create an MP3 song list to play with. A top grade arranger keyboard is around $3,000 new while Biab is a few hundred and with the RT's sounds great. I bought my Korg used for $1,300. That can still be a lot if you're on a tight budget.
If you decide to try out One Man Band, let us know how it works out, the owner of that website will post here occasionally.
