I'm with Andrea in this one.
Everybody should do what they want, explaning how and why they do it and that's all.
We can all learn from each other... I'm only playing live since one and a half years ago and I'm sure I would have things to share with everybody about different issues, the same way people like Uncle Dave (with a lot of experience) could share with me.
About the thread: "onboard speakers", my previous keyboard was a (I was "poor" at that time...) Roland VA-3. I know the onboard speakers wasn't as good as another keyboards, but anyway I would never play ONLY with those speakers. I'm very used to studio monitoring, and so I need a clear and transparent PA system, even at a very low level. I used the onboard speakers alone only one time, in a small church playing only organ (the singer didn't need amplification).
I got a non-onboard speakers thinking of this and who's gonna tell me I did it wrong?...
If I find this post about onboard speakers, I'll try to learn something from other people experience and maybe express my opinion, but I'd never tell anyone he's completely wrong and I'm the right one.
Let's just share our experience, our little secrets, our tricks, our way of playing, the equipment we use and let's all "upgrade" ourselves. WE'RE ALL IN THE SAME BOAT!! So why not only help each other?!
(Sorry everybody about the bad english but I'm a little stuck at it...)
