Dear Kronos Associates and friends,

A section of keys started hammering metal to metal at my last gig, annoying and intolerable noise really. I'd replaced the hammer stop felt about five years ago for the same reason. So I opened it up and sure enough a section of felt has totally worn out again from aggressive play. I'll get with Partsisparts.net for replacement felt. But quite honestly my memory's not so great on how to do it so does anyone out there have a video link for the procedure to replace the hammer stop felt? I'm pretty sure it's the RH3 hammer action. Thanks for any info you can share!

If you replace the entire line of felt, it takes a while since you have to remove all the keys (the whites are locked by tiny safety tabs which must be undone gently), then all the hammers. Especially, be careful NOT to touch the lubricated parts as this type of lube is quite hard to find and expensive. Adding the wrong type of lube can end up in a delayed disaster.

Thank you for this info. Unable to find the felts so far. Any ideas where to find that special lubricant?

Check Syntaur dot com for the felt strip.

This worked out great, thank you for the tips especially on the lubricant. I didn't know and would have been tempted to clean it all off only to realize I had none to replace it. I'm interested in getting a tube of it so if you or anyone knows where to get some please advise? I did my best to clean up what was already there and just put it back together. I had some trouble with the spring assembly on a few keys so had to disassemble one more time and fix those keys where the spring had dropped. It was THEN I remembered how to do it properly! I'm a bit slow. I took advantage of the opportunity to replace a few broken keys all that the same time. But it all worked out fine. I have two Kronos 88 keyboards, one for studio, the other for road. So I could rely on the K2 until I got the original version back up and running. The new felt in the original action is a bit mushy still, to be expected and will take some time to break in I imagine, but I'm pounding away at it. I changed the velocity in global to compensate for it and now and it's fine. This worked out really great!

Oh one other question for anyone? This is a stupid question. But when I make changes to and write an update to a set list, to which file does that update save? .PCG, .KSC, .KGE or .SNG? I write new set lists a lot and it'll save me time to just transfer those updates from one Kronos to the other via USB flash drive. Thanks for any help on this.

Hi Gaston and glad your Kronos action is now comfortable again. Wink

About updating setlists, in fact the write function in prog, combi or setlist mode doesn't actually create any usable file by itself (it only writes your updates in memory), so you also have to save your Kronos contents in Disk mode. Then the newly created PCG files will contain your Programs/Combis/Global stuff to reload later if needed, just like an "undo" function if you later do a mistake. For example, someday you might see an interesting third party sound library to test or a nice PCG file to load and without your own saved PCG files, you could overwrite stuff you might have worked hours on. So it's important to remember to do such saves often. Cool
