This discussion makes me take a step back.

Virtual arrangers and daw's replacing hardware arrangers for creating music at home has followed common studio use...will it, can it, should it totally replace an arranger for live use shortly? When some of the biggest proponents of keeping arrangers from extinction are using it, is it surprising manufacturers commitments and attention to arranger development are shrinking?

Why shell out thousands when far less will get you the same thing with software, a laptop and key controller?

Or does it?

Its been said that most of us don't even approach the full use potential of our instruments. I fear the increasing complexity may discourage some of our "graying" age group, and excludes some that aren't very tech or computer savvy from using virtual setups all together.

Do you want to do proportionately more programming than playing, or more playing than programming? Maybe that's the question to ask when deciding what will work for you...I wonder how long both options will exist.
