You really don’t need to buy anything to learn about those topics. Just use google. There is a ton of information out there and it’s all free. After doing some research you can always ask questions here. Speaking of questions did you know that you can ask google a question? For instance you could ask “what is the difference between mixing and mastering musical songs” or “what does a compressor effect do” (do not use the quotes). You may have to dig but you will come up with your answer.

Forget what others are using and use what is best for you. As I have stated I use Sonar, but it is version 5.2PE. The current version is 8.5PE so my version is about 4 years old but it does everything I need it to do. My advice would be to pick one sequencer and learn how to use it. Try the demos as well as RealBand and pick the one that is most comfortable FOR YOU.

If you want the chord symbols to scroll by in Sonar you have to type them in. I very rarely do that. I just print out either a chord sheet or lead sheet with the chords from BiaB.

An afterthought: I don’t know what you know or don’t know about sequencing but I’m guessing based on your questions that you are a beginner; if I’m wrong I apologize. If you are just starting out I would concentrate on RealBand. It will do what you want/need it to do I’m sure. Listen to some of the very professional sounding music that has been produced with RealBand in these forums. Also I believe it has the easiest transition path from BiaB.

Good luck – I hope this helped.

Doc-take it easy John this is just a sharp scalpel. It will not cut deep so don't worry.
Me-I'm not John
Doc-I know, I am!
