Hi miden.
I read your original post before any edits, and I have to say mate your way too hard on people here and yourself.
I don't think you understand what people are saying in general here.
I personally really liked your demo and the mere fact that you could over hit the notes is excellent in my opinion. It really shows off what is possible, and it gave a real world response from the sound. Not another perfect bubble keyboard sound.
So for what it's worth, I think your demo accomplished everything you wanted, and I personally enjoyed it. If the other sounds are like that in the Library, I'd love to buy it myself.
A Guitarist would hate the buzzing, but that's a different story. Do you honestly think there are many guitarists that even understand what a multisample is. Their needs are different than ours.
Hope you understand what I'm saying and keep on posting your demo's. Don't ever let anything said on a forum stop you from sharing your music.
Some people will never be pleased no matter what, so when you do something don't do it for them. Do it for yourself and those interested.
Regards.
James.
