Myself and Nedim both have the Kronos. I use the Kronos on Stage for weddings.
It is a breathtaking instrument, and I can do rudimentary arranging playing using both the Drums, Combinations, with/without Karma. Karma gives the Kronos lots of randomness you won't find in an arranger.
Go over to Korg or Karma-Labs and check it out.
It complements the Tyros 4 perfectly.
We used an original Korg Karma keyboard on a few tracks in the studio (making an advertisement), not that many years ago, and it was a pretty cool instrument.

The
Wavestation was another cool Korg synth my buddy had in his studio (since sold the instrument)...have you ever tried one, Al?

PS...Donny should be using a Kronos with his microArranger...that would be a nice combination...and still nice and compact.
