Sorry I missed your response before I posted..
No insult was intended..If you played the piano parts by ear, you must already be familiar with Tune1000's sequence, because you are dead on..
Are the piano parts part of the style?

Here is another possibility, maybe the style is taken from the sequence..

Way too close not to be associated one way or another..

I modified the sequence as above and came very close to what I heard in your song[of course without a Tyros ..can't duplicate the ending..
So this reinforced my opinion...right or wrong

Scott I also agree that a good arranger player can do a great job, but please don't toot the horn as if players using sequences can't pull off great performances...you can be just as skillful...besides that even great arranger players can't play my rooms without some sequence arrangements.....Sounding like the record is very important in some venues...
Personally, I prefer playing the old fashion way...left hand bass, drums, piano and a color sound[organ/guitar etc]..

BTW, making our own sequences is great, but I only know a handful of people that can do it like the pros....I don't think you are one..
It takes a super ear, great timing and lots of patience.....yes I tried the business in the early years...nearly impossible to make a living in the sequence business..

Again Wolf with or without sequence help...a great job on your tune..

And No, I don't want a Tyros2, even though it sounds "nice"..
