Hi Icelander, I just noticed this post, though it is an old one. I assume that by now you have made a choice about Korg Arrangers.
I have, yes, but perhaps not quite in the way you might expect, for as things turned out I actually ended up not getting a Korg at all but a Roland (E-A7)!
Now, this wasn't really the plan, I'll admit, but I started this whole search a good while ago and in between "something happened" on a rather global scale that changed everything, you know (for everyone everywhere!). So I was forced to change my parameters from what was 'desirable' to what was actually
obtainable - and this was the result.
I decided that maybe I should give Band in a Box a try.===Just add a MIDI keyboard of your choice and save an awful lot of money
Well, obviously I already do have BBox or else I wouldn't be on this forum
But for me that still left out the need for sound sources that a bare boned Midi controller wouldn't have (I don't sing and all my music is instrumental, I might add), among other reasons, so I decided against that, at least for the time being
The good news is I still ended up saving "an awful lot of money" since that particular Roland is much cheaper than any of the 'desirables' I initially had on my list.
I appreciate the insights regardless, if not but for future references
