My son( 8 yrs old) has 61 keys touch response keyboard recently bought but we started classes later and found piano teacher ( we were initially looking for keyboard teacher) and wondering How long I can use this keyboard ? My son complains of keyboard keys being so soft and he says it will be difficult for me to switch to Piano as I will used to it ( must be his way of pursuing me to buy him piano) but I am non-musical mother hence don't know what to do ? I am not sure how long he will take interest in learning though at this point of time, he seems serious. BTW, he is about to finish Easiest John Thompson Book 2 and I guess pedalling thing will start soon. I have an option to extend only sustain pedal with this model.
