I suppose in all my years I've played arrangers, I've never played a Bolero style. Yours sounded so good, that I called one up on the SD7 and recorded something. I called asked DNJ if it was o.k. if I posted it for comparison and he said sure. So here it is. Certainly different from the Korg. I like 'em both, but then I BOUGHT them both so I should.
It was the first time I really used the onboard audio recorder. Levels may have been a little hot.
