I need new rubber contact strips for my pcr-30


These are notoriously unreliable - the contact pads age whether they are played or not.

Roland/Edirol should be able to supply a set of replacements if you can track down a service agent.

In my experience ( in the UK ) their service sucks.

They have an ex-employee who does the warranty repairs from shed at home and that's it!

They won't deal direct with the public and their sales chain can't be bothered to order parts.

Good luck.

Edirol PCR-50 wont output any data for most keyboard keys


Yes people it can be fixed by yourself at home, cheaply and easily. I’ve got an Edirol pcr-80 & prc-a30. Both have had intermittent key troubles and keys that just don’t work anymore or low/high level compared to other keys. These problems seem to start after a year or so. I’ve paid hundreds of dollars getting them fixed until I tried this on a whim. The contacts under the keys are a carbon-based contact so cleaning them with metho/alcohol just dries out this carbon. Some people say cleaning them with a pencil easier helps and it can do slightly but not properly. What you need is “Graphite Powder”. (Link for a picture of a appropriate product – just cut and paste it in your Internet heading bar, or Google image search graphite powder…)
http://images.google.com.au/images?hl=en&source=imghp&biw=1024&bih=1080&q=graphite+powder&gbv=2&aq=f&aqi=g1&aql=&oq=&gs_rfai=
Graphite powder is a dry fine powder that is conductive and perfect for the job. You can purchase at any locksmith – maybe a good hardware store, and it is sold as “non liquid lubricant for locks and machinery.”
All you need to do is unscrew the case, remove the springs that hold the keys in, remove the keys. (White keys first then black keys. Keep in order.) Peel off the rubber strip under the keys and turn over so you can see the little carbon nipples that touch the circuit board. (2 for each key) Pour a little power out on a sheet of paper and use a cotton tip bud to apply a little powder to these. Now apply a little to the carbon contacts on the circuit board where the little nipples touch. Do all this with your midi keyboard plugged in to your computer/synth etc so you can hear how you’re going with getting contact before you put it all back together. You might get a key or two going off when doing this because the graphite power is making a continuous contact across the circuit board. Just blow/lightly wipe away excess to stop this but you want to leave all the contact points evenly (if slightly) coated. Try touching the rubber strip contacts with the circuit board contacts to see if you can get a sound. This can be a bit tricky to line up and get an even contact. This sorts its self out when everything is back together.
Now put back the rubber strip. I used I tiny screwdriver to help push the rubber guide back in the holes on the circuit board. Now put the keys back (black first – with the short springs then white keys with the longer springs) screw the case back together and let me know how you went.
This I think will dry up again in time but if you get a good bit of use out of it you can just do it again… For free…

Edirol pcr 50 dont know how to work


Dont forget that the PCR50 is a Midi controller and as such has no "sound" of its own. You must have Midi compatible player or composer type software (like Reason, Cakewalk, Sonic, etc) to link up to the PCR50 to get any sound.

Some keys not triggering when humidity low.


You might want to try take a can of compressed air as used for computers and blow out any debris that may have built up.

See if that fixes it. You might also want to check out the editol web forums and ask in there as I am they might have more idea

Replacing Key Contacts


I have a PCR-30 here that has developed several dead keys over the years.  I took the thing apart to clean the contacts and see if I could improve things -- unfortunately, it had the opposite effect, and I was left with only a few keys that *did* work.
I have since found a solution though, and now have a fully-functioning keyboard once again!
You'll need a tube of pure, dry graphite powder (only a couple of bucks from your local auto-supply shop), a tiny craft paintbrush, and a willingness to take your toy apart :)
Open the PCR up, and remove the springs holding the keys on.  I used a slotted screwdriver to jam into each spring, and lift it off the hooks.  I'd suggest keeping the keys in order to make it easier to put back together.
Now pull off the grey rubber contact sheets.  Clean out any dust that's under there, but don't be too abrasive or use chemicals.  We want to keep the existing contact material intact.
Put a little graphite powder in a small dish.  You won't need much.  It may seem a little clumpy, but it's actually extremely fine.  So fine, in fact, that if you smear it on your fingers it feels greasy, despite being completely dry.
Dab your brush in there to break it up, and get the brush well-impregnated.  Paint some powder on each of the contact surfaces both on the board side, and on the back of the grey rubber sheet.  Be careful not to connect the spaces between the contacts on the board... graphite is highly conductive, and you don't want an always-on key.
As you smear each contact with graphite, you'll notice it become a little shinier if you look at an angle.  You'll also get powder spattered around places, but don't worry.  Just blow off the excess.
Once you've done all of the contacts, place the rubber sheets back on (this can be kind of a pain, getting all the pegs back in the holes.  Hook it up and give it a test (just use your fingers to push the rubber pads), and repeat the process for any keys that still aren't working.
Once they're all back to 100%, replace the keys and reassemble.  You're good to go!
-Ben
