Your points are well taken but I doubt if many people here have experienced the same frustration as yourself.

Most of the folks on here are arranger players, so they're quite happy with their arrangers. 'Horses for courses,' isn't it? There seem to be two separate camps - arranger people and synth/workstation people. Almost a Hadfields and McCoys situation at times, I think. There are overlaps, of course, and no doubt you'll get some interesting replies from them.
