I've learned my lesson very well ....this is why I'm sticking with Yamaha...I have changed so many times with every model of every manufacturer and for a busy giggin pro as myself its really a strain to crunch down and switch all setups, convert, mix & match styles, sounds, etc, when you switch companies. I for one have had enough and realize it ain't no big deal and it's not a big change sound wise with today's units if you know how to make it sound great, especially if you use the arranger to back up your vocals as an accompaniment source. Most sound so good already.
