[sdiy] Chemtronics Rubber Keypad Repair Kit, was: Roland JP-6 / juno 60 LFO trigger button

[Bob Weigel]

I had some success also.  However problems repairing

* A Dx100

* My own CS2X

* had to do some others multiple times because the stupid paint doesn't 
always form a flat enough surface when it dries!

It's ok for push buttons I think.  But not keyboard movements.  The new 
kits I'll have ...you just slap them on and press down with your 
thumbnail and voila.  Brand new contact 100% of the time.  The time you 
will save over painting all the contacts in a 61 key unit is enough to 
pay for the kit..not to mention the lowered likelihood of the paint not 
drying flat enough on some of them.  There's no comparison. -bob
