This is not an arranger keyboard synth but a form of toy, small hands = small keyboard keys
The manual is sufficient
it is very easy to use, not making head
My ERRF has since 1999, I like most is that we have no fear of damaging it, I find it a bit expensive. The sounds are really good but then sr pourraves really in the pourraves What we would do our children not gter Nol? It is for them as they are given with gouache paint brushes to paint on 5cts 10g printer paper: the brush only drinks water he rejects the paper that does not want: feedback, it warps made ditches and everything flows to make beautiful EMDU tasks, has the FCHE DEFINITIONS with paint. With this machine is the same thing except that a 200 score!
Sr good exprience with it did not refer this choice but it's too late!
