I've owned my Yamaha PSR2000 for over 4 months now and must always first load a Registration Bank & Reg Memory before any sound can be heard from the KB. This procedure has become a 'second nature' habit for to me now, but I somehow recall (when I purchased the KB?), that I was able to initially power and then play it (hearing the sounds), without having to load in a registration bank first. Is this just wishful thinking on my part, or are others of you able to initally power up and play the PSR2000 (hearing sound when playing the Keys) without having to load in a Registration FIRST? Thanks in advance for your response. - Scott
