i'm interested in buying an akai ewi 4000s and i'm wondering if its really worth it to buy everything off of patchman. they claim they do a bunch of stuff to set it up, but is it really that much or even necessary? i'm liking the vl70-m with the mod chip and the presets, but the wireless midi is a little excessive. i can find both the 4000s and vl70-m for about 500 each, and that would save quite a bit but is it worth it to get it all from patchman? or just the chip and presets?
