Isn't DAW functionality speculative? Realband recorded audio and will let you split tracks into clips but I don't think it did everything Cubase Sx could do did it. What are things that RealBand does better than
Cubase 5
Sonar X3
Similitude
Reason 7
Apple Logic
Orion Synapse
Reaper
Fruity Loops
Ableton LIve
All of these are so different from each other

We should respect how our competitors do things because more or less most of these aren't that expensive. So I always try to support the creators of products when I can.
