I'm thinking of buying a Kronos 61 key... A while ago I purchased a 88 key Kronos but sent it back... I just could not get by the sound of the keybed noise thumping. When people heard me playing they would ask what is that noise from the keyboard. Well, my question, does the 61 key version have a silent keybed. I would think it does being more of a synth action. I don't have a place near me where I can listen to it. Hopefully someone can answer this before I buy. Also, does the 88 key sound better with piano sounds because of the graded hammer action vs synth action? thanks Ron
