Bob,
After 10 years you have a lot to catch up on!
It's a whole new world in digital audio.

Maybe the best way would be for you to tell us what you have to start with, and what you'd like to do as a good starting point.

Ex. I have a PC and want to play some keyboard parts into the BiaB song.
Or I want to record my singing and put reverb on it in my BiaB song
etc

Then we can ask the next questions (like which sounds do you want to hear when you play that keyboard) and advise what we think would be your next step to get where you want to be.
Just a thought

I do not work here, but the benefits are still awesome
Make your sound your own!
