You so obviously don't know what you're talking about, that I'm tired of wasting time and energy.
I have made a living doing NOTHING but playing music professionally for many years. I think that makes ME a pro.
I don't have a job repping keyboards. I don't have a job teaching, honorable as that is. I'm not retired from anything.
FYI, Roland US has contacted me about the pianist mode and assured me it will be corrected in the next OS upgrade. Free even. There are a couple of other minor bugs that are also slated for fixes.
Someone asked for opinions about the BK-7M from USERS. I tried to help. I'm sorry I did.
I played a Tyros 4 for several hours on each of two occasions. I can't recommend it. Who CARES if I can't recommend it? I'm pretty certain you don't, because you have found that it fits your needs. I'm also certain that if you were paid to represent Roland, as you are by Yamaha, you would have a much deeper knowledge of the module and be touting it instead of running it down to suit your own purposes.
All you know about it is that three of your customers, and three people here tried it and didn't like it. You even tried to lump me in with them, which just isn't true.

Buyer beware??? Are you kidding me? Did you see that long list of faults that you get in a $4900. Yamaha? Give me a break. I wasn't talking about hearsay; I was speaking from personal experience.
I'm talking about a module that costs considerably less that $1,000. It sounds terrific, is easy to use and it suits my purposes at this time. Why do you insist that it doesn't?
I don't like to argue. Apparently you do and I'm finished with this thread.
You can now come back and twist something else around and you will win. Congratulations.
I feel you are hurting this forum. Just my opinion, you understand.
I'm sure Nigel will delete my posts again. I'm past the point of caring, because of you. It's not me.
