My CP-70 seems to be regulated like any other Yamaha grand. Key height is determined by the panel that acts as a key stop rail, though I'm sure there's a number for it somewhere. On their small grands it's 2 11/16". Blow is 1 3/4", let off is 1/8" and dip is 25/64". Sorry I don't have the metric equivalents available for you, but I'm still using Imperial measurements since that's what all my tools are. >I wonder also if the hammer covering is leather or corfoam, as used on >other yamaha "leather" parts (If I am not wrong on that one !) It looks like leather to me. Seems to wear like it too.
