Hi Andy,
Long time no see! I'm getting the same problem and it does make a 
difference to the tuning. You can tell by swapping roller assemblies 
between different keys. I can free up most of the "stiffies" with 
cleaning/oiling but not all and then after a couple of weeks they are 
stiff again! I also get the same pulsing feel on some of these keys but 
on inspection can't see lumps on the roller surface or capstan. Makes 
me wonder if the roller axle holes have worn unconcentrically(sp?).
I see Markus is now selling pinch rollers singly for $5 or offering a 
fitting service. Also Martin told me recently they should have some 
soon. I think I'm going to replace a few. What we need is some 
advice on how to fit them and if axles are supplied with them - how 
about it guys?

Dear all - advice needed.

I've been doing a good bit of recording on #1145 lately (at last!), and 
I've been having quite a bit of trouble keeping individual notes set 
up. I'll adjust everything before I start, then after 1/2 hour, some 
notes are 'out' again. Also, I can feel a distinct vibration on certain 
notes, and adjusting the pad/roller doesn't seem to make much 
difference. I tried spinning the rollers by hand, and while some spin 
freely, the problem ones barely move. I'm not terribly technically-
minded, but am I right in thinking I have a problem with these 
rollers? Is this a stupid question? What can I do about it?

Help!

Andy T.
