It's a one man band. The 'members' are greatly imagined.
It's always a plus when 'other' real musicians can play the instruments on your projects. There's a certain element of freshness and surprise when you have someone play your stuff on a real kit or use their own bass and amp. Having real people read and perform your string scores and brass arrangements might even be shocking! Especially if you can't pay top dollar for their services.
So, until budget finances permit such expenditures, I'll be satisfied to perform all the member's parts myself on my DAW.
