Tom,
Great track. I can only wish I had the technical skill to cook up something this polished.
It sounds like your inspiration are those splendid extended one chord instrumental tracks Miles did when he first went electric- i.e In a Silent Way. A difference I'm hearing is the bass part- I remember a more simple bass line that held down the groove. Nonetheless, I like the part you composed. And the keyboards are lot more up front. It may not be possible to emulate Tony Williams with a drum machine. (These observations could be totally meaningless in terms of what you are trying to do.)
Great stuff. Keep it coming.
Bert
