Hi Diki,
let me tell you the names of a few of the great sounding styles John Smies created for the Korg Micro Arranger that did not come with the factory presets:
Steely Feel, Stand by Me, Hammond Jazz, A Whiter Sh, Lodi, CountryRds, AlwaysMind, Maggie, Dire Straits, Wonderful (Tonight),
Let It Be, Groovin', Hotel Ctt (California), plus great Latin, and Soul Jazz, and lots of slammin' funky "groove" styles.

My favorite of his much enhanced programs, or what I call, John's "sounds on steroids", are the electric pianos and B3 organs.
The variety of realistic vintage Rhodes are incredible.
I especially like the way John set up the rotary Leslie effect on many of the Hammond organ programs where I can easily switch speeds: Slow/fast/stop;
Recently, I include the Korg Micro Arranger when I gig . . .
and everytime I do, I receive many compliments.
Thanks, John
