Mind that the E-A7 is not a high-grade arranger, I'd rather get a BK-9 with a discount. An E-A7 following a Tyros 5, I guess this won't result in much joy (and I've been a long-standing Roland supporter).
If you don't need the arranger functions, why not a synth? I would definitely wait for NAMM and Musikmesse in spring.
Actually I'm hoping my BK9 will work as a Synth in a band setting as well as it does as an Arranger. I'm sitting in with a Blues Band with hopes for some future gigs and I've spent a considerable amount of time progamming some setups for that. Mostly Hammond / Piano stuff. Very different from my Arranger setups. I thought that if this band works out I would get a Roland VR 09 or Hammond SK1 to go with my Casio Privia piano. Just for my own info I contacted Roland and found out that the BK9 has the same organ engine as the VR 09 so I don't need to spring for a new board. And the Pianos are as good as the Casio so unless I really want two keyboards I'm good there too.
This Sat. I'm doing a OMB in a new place in Habersham SC ( look it up, its really a cool little upscale town ) and it will be all Arranger so my BK9 is getting a workout.
BTW where did you see them discounted, I still may want another.
