new sliders on synths like the arp odyssey. i was thinking of cutting
some slits in some kind of cloth or something. ideas? things to avoid?

Avoid at least the foamy kind of packing cushion material, or whatever 
it is called (I'm not a native english-speaker thus am lacking 
vocabulary on these materials ;). Maybe just see the pic under "dust 
cover.. " from my repair doc (more towards the end) at 
http://kewlers.scene.org/bitchard/diy/Odyssey/odyssey.html and you'll 
get the idea faster than with me babbling on and on :).. This material 
was crumbling slightly even when moving the sliders and no doubt 
would've been a whole lot worse even after a year.

I'm thinking about looking up something slightly more rubbery but 
retaining this foamy feel to allow the foam to recover it's shape around 
the slider. You know, maybe sth with a lot smaller and dense "air 
bubbles" or cells or whatever they're called. As you can see from the 
pics, it doesn't necessarily have to be a thin film since there's plenty 
of room between the slider and the front panel. Having something 
slightly thicker that'll compress a bit when inserted between the 
sliders and the front panel helps keeping the foam in place, with a thin 
film you should probably tape or glue it in place. The stuff I tested 
was maybe 2-4 millimeters thick.

Anyway, if you come up with sth, do share what was your solution. I bet 
we're not the only one interested in a mod/hack of sorts ;)

I believe the stuff you refer to here is "foam rubber",  which does indeed 
deteriorate and leave a rather nasty residue as it ages...

Perhaps a visit to any bicycle or tire shop will yield an old inner tube, 
unusable in its current context but providing bits of usable rubber?
