Hello everybody, First of all, I'm not an expert... My son plays the piano quite well. I would like to give him a device that offers alternative sounds + which effects, without having to become a professional first (desire to deepen already comes...) So it should be relatively fast fun and give as many possibilities as possible. 1 Does this model +/- have these characteristics? 2 Can it be connected to the speakers, e.g. through a stereo amplifier, or are other interfaces required? Thanks. Marcello
