Yep. I did it for years. Ended up using Drums on Demand Loops, Guitar loops (either created by myself or purchased, Stings I learned to and could arrange, Bass was my biggest weakness.

Now I can assemble the same "loops" and play them and change them "live" in pre looped patterns. Any leads I do are done like vocals. Live and at the end of the tracking of the loops.

Arrangers like sequencers don't replace talent they are TIME SAVERS. No 20 something should be using an Arranger. they should be diving into a full blown workstation.

The first thing that attracted me to arrangers were the quality of the voices. When I heard them in the style players the decision was easy. But I will still have to write entire arrangements for some music. Some songs don;t lend themselves to loops.
Others are completely legato in places.

Talent is not reserved for those who play a particular keyboard. Nor is it self assured.
Talent is like the Right of Way....You never "have" it. It can only be yielded to you.

I may find Usher talentless but his success belies my opinion but does not disqualify it.
