[sdiy] U-20 questions

[Tim Parkhurst]

Hi All,

I love the sounds on my Roland U-20 but it has two problems:

1) Funky key contacts. Many keys don't sound, or trigger a dozen times when
you hit the key once (a really neat effect if you could turn it on and off).
I pulled the rubber contact strips and used conductive ink to "re-plate" the
contact pattern about two years ago. This helped a little, but now the
problem is as bad as it ever was. Is there a better way to refurbish the
contacts, or do I just replace the contact strips? And where do I get
replacement contact strips? I'm just using the U-20 as a sound module right
now, and this is a reasonable workaround, but the machine has a nice
keyboard and I'd probably use it as my master controller if the darn thing
worked properly.

2) A Two line LCD and four buttons do NOT make a user interface!!! Are there
any editor/librarians for the U-20 out there? I know Unisyn has a U-20
'module' but I just don't have the $200 or so right now to spare. Any other
choices?

Thanks as always!
