Yep, that's pretty much what I expected from you, Kingfrog...
Nobody gives a damn what you USED to do, especially as it wasn't playing (there are karaoke singer forums where you would be GOD! Which is what I feel you need, from what you post).
A washed up, retired, has been imitator of another, far more successful singer is EXACTLY who needs to come here and tell us (from his perspective of being unable to play) what our mistake is in not choosing the same equipment as him!
As I said, were I to beard you in your den, say a singer's forum, and admit I couldn't sing, needed Auto-Tune on everything, and had to punch in on every line, I don't think you would be particularly impressed, no matter HOW well I played keyboards, or who I played with (my list of credits includes many of the industry's greats). And if I verbally abused you while still admitting I couldn't sing, your patience would run extremely thin.
Mine has run out.
In future, I will not be responding to anything you post. I hope that you have the class to not take this as an opportunity to shoot me in the back, but, well, let's just see...
