The Tyros3 is a "workstation", according to the definition you yourself posted.
Ahh... then I didn't make my point clear enough.
I meant as in a Synth (not an arranger) that either produces it's sounds by Virtual Technology, or PCM based generation and that has a full blown sequencer.
Not an arranger keyboard that has a very limited on board synth like the Tyros and a basic sequencer with no sampling.
That's why I mentioned that if we stuck to KORG keyboards only it would be quite hard to define a difference between them because KORG Arrangers are just as deep and fully programmable as their workstation.
Neither carry any read only factory preset data, KORG keyboards are all fully programmable unlike Yamaha Arrangers which have small user memories and limited abilities for programming.
It may not be your cup of tea, but it is certainly mine, as well as many other professional players...it is exceptionally versatile for both live and studio work.
"Workstations" are too difficult for many players (pros included), hence the addition of arranger and arpeggio features.
Well there you go, your pretty much pointing out another main difference between arrangers and actual workstations yourself.
IMO arrangers are superior to an Oasys with Karma...try playing a polka or an old fashioned waltz, not to mention most other standard styles.
You don't understand the concept then.
It can certainly do that and far more than an arranger. It just doesn't come form the Factory programmed that way because KARMA only comes on Workstations which are not mean for people who want to play Polka's.
I uploaded this basic example a few days back to show KARMA playing like an arranger keyboard Style but with the added bonus that it's also able to do things an arranger can't like add a certain amount of randomness to the pattern.
For example have a listen to this.
http://www.irishacts.com/misc/file3.mp3 There's nothing really locked down to a set pattern like arranger keyboards are. Everything is being generated in real-time and if you listen to the drums for example you will hear them play more naturally just like real drummer will.
That's not me activating fills or doing anything other than playing 2 different chords. Even the main variation change you hear is generated in real-time by KARMA. It's not me changing to a different set of patterns. It's all the same data doing different things in real-time.
