I'll let it get up to room temp then I'll give it a try...First thing I notice Very nice semi-weighted keybed 76 keys...Keyboard weight is fantastic less than 21 lbs...Super nice condition...I always wipe down with disinfecting wipes New or Pre-owned keyboard. The only thing and I knew this when buying NO Music rest...If anyone has one they would like to sell let me know please...I still use sheet music a lot at this time...Maybe I can order one from Roland US...That's all for now...Harold
