I missed the original version, but this sounds very good to me; flowing changes and with such a big band I like the horns being out front... although I`ve no idea how you created them, they are impressive
Hi, Robert.
Thanks!
The original version was only slightly different in content, in ways probably only of interest to me.

I use a wind controller called an
EWI (electronic wind instrument) that's hooked up to my computer via USB. When I blow into it and press the buttons, MIDI information is sent to my computer, which triggers virtual instruments.
The "virtual instruments" are basically physically modeled versions of the saxophones and flugelhorn. That means that - unlike static samples - the timbre and volume are responsive to the breath pressure. It's a lot more expressive than playing a sampled instrument.
Mario also uses one.
Thanks for listening and posting!
