Definaltly agree they are different. Creating the music and preforming the music are two different worlds. Rarely do the talents that go into creating a piece get the credit that the Singer who performs it gets . Or the money.
We were discussing Donny's find of what I think is a great new tool for the performer. Creating the music it plays takes lots of different tools and talents.
BTW I really liked the way the unit morphed from one song to the next. I wish my Arranger could do that.
