2b,
Not sure where you are aiming at...
"midi sounds"... I think it is a bit broad. Meaning a DAW may include a variety of midi loops selection, but honestly, I do not believe that midi loop content should be a decision maker in choosing a DAW. There are dozens (if not hundreds) of companies that sell midi loops "by the pound" not expensive at all, some packages have great many..loops and other midi parts that you can use in any DAW.

maybe I did not understand your question correctly, just trying to help...
