Jimmy, Jazz or swing needs a great brass section.
My set up;
1-Left hand Synth brass
2-Right 1 Strong deep brass
3-Right 2 High Trumpet (Up one octave
4-Chord harmony, when added, was a third type of brass – Three to four notes.

I keep working one hand against the other trying to create a real sounding brass section. Left hand leading the right – Sometimes only left hand.
A must – A high amount of Touch Sensitivity so that I can control the volume of the instruments, especially the left hand.

Your Kn7000 is capable of doing it very well Jim.
