Gary.., I mean no disrespect my friend, but you couldn't be farther from the truth on this issue. It's not your fault because you don't play modern music, and as such honestly don't really know what an individual needs the keyboard to be capable of.

I'll give you an excellent example. I have recently attempted to create a modern style of music on my PSR-S700. The S-700 is a MOTL arranger keyboard that (price wise) was right next to the workstation MOTL models (that were priced the same).

Not only do current arrangers lack the sounds and (just as important) the styles to create modern music, but some MOTL arrangers (such as my S-700) are lacking MAJOR abilities that are CRUCIAL to creating modern music, and without them makes an arranger very DIFFICULT to use for these styles. Also.., not to forget the absence of "ASSIGNABLE" REAL TIME CONTROL KNOBS on many models.

Unless it's hidden deep within a menu somewhere that I've not found.., my S-700 (and I would assume MANY others in the S series) lack the ability to SYNC a tones LFO settings to the internal midi clock.., AND more shocking the inability to SYNC some specific EFFECTS settings to the midi clock. It doesn't stop there either. Another HUGE omission you'll find when creating user styles (at least on the Yamaha's) is the mod wheel CANNOT be used to adjust crucial parameters within style parts and RECORDED to that style part.

For example.., if I was to create a Dubstep style, I would need the ability to not only modulate the sound with the wheel, BUT the ability to perform other functions at the same time such as:

-Using the mod wheel to control the LFO rate of the selected tone.
-Using the mod wheel to open the filter
-Using the mod wheel to control the LFO rate of the chosen effect.
-Using the mod wheel to control DSP depth for distortion.

These are just a few things that are CRUCIAL not only to Dubstep, but to MANY styles of electronica. Sure I can make these settings when playing a sound in REAL TIME.., but the purpose of the Style Recording is also to SIMPLIFY song creation. Without the functions I mentioned above means that the user has no choice but to MANUALLY play each of the parts through the duration of the song. There's nothing simplistic about that, and it's an EXTREMELY time consuming process.

Now.., I haven't had the chance to really dig into a Korg arrangers style recording functions.., but if there was ANY arranger on the market that I would "assume" had these abilities.., it would be Korg (who IMO have the BEST combination of a synth/workstation/arranger on the market today).
