First, the good. This is a GREAT sounding string machine and vocoder. It really nails the classic Roland sound, and is a sweet looking machine. However...build quality is quite disappointing, particularly for the price point (I bought when these were around $700; Behringer has since dropped the price). The keyboard feel is pretty mediocre (I understand Behringer designed it themselves; might be wise to outsource this to a manufacturer with some expertise) and some of the toggle switches are already starting to fail (require multiple presses to engage / disengage). I love the sound, but don't have much confidence this thing will last for more than a few years. Disappointing - really wanted to like all this new Behringer gear and for the most part it does sound great, but quality is still pretty poor and remarkably uneven. Oh well - I guess you do get what you pay for, don't you?
