Another thought on this subject.
Back in the early 90’s I met a great One Man Band. He used several keyboards to get the effect we get out of our present keyboards. He programmed his instruments – sax and clarinet, with a lot of vibrato, put them slightly out of tune and cut a good part of the bass. He repeated that thought with the rest of his keyboard.

He sounded authentic – he captured the time. A true pro.
