Vadim, what you are not getting here is that most top of the line arrangers are virtually as powerful as workstations as they are arrangers, whereas most workstations have NO arranger capability at all.

Both the T2 and the Korg line (not Roland, unfortunately) allow almost as much voice editing capabilities as their workstation cousins, have capable samplers, and extensive sequencing abilities (the Rolands have that, though!).

Your minivan/suv analogy only exists in the minds of users, not in actual capability. What we have in an arranger is a minivan that, if you press a button, morphs into an SUV! Something no workstation (even Oasys) can do......

As I said earlier, the only REAL difference is the sound-set, which can be remedied with the sampler section, and the availability of good urban styles. The first manufacturer to address this is going to make a fortune..!!

I do a lot of production work myself, and if at all possible, I will always start with recording a 'style sketch' into the arranger's sequencer. I can then work on it in traditional workstation workflow, but with the advantage that the whole basic tracks effort takes a fraction of the time it would with a workstation.

I can then add in recorded audio, more parts on external MIDI gear or soft synths to give it that extra sheen. But all in a fraction of the time a traditional production takes. THIS is why an arranger is at the heart of my production workflow. If workstation addicts want to take more time than necessary, that OK with me.....

So rejoice that, in one keyboard, you have an arranger, AND a workstation. Most soccer moms would LOVE a mini-van that morphs into a sporty SUV!
