Question about Yamaha NP 30 76 Key Lightweight Digital Grand Piano with Touch Response

Roland 3000 Digital Piano 88-Key Full-size weighted keyboard

Some keys don't work at all (two); several keys must be played quite firmly in order to work. This occurs across all voices.
Oh, and one key sticks.
1) what causes this
2) who is my best bet for a correct fix - electronics specialist, music store, ???
3) who can likely fix it right, for the least $$$ (I'm broke)

    i have the same problem as you and am looking to fix it......however, i do some electrical work, and computer hardware stuff too, and i have not found the problem yet.  I have noticed that the board bows slightly in the middle due to play and general gravity, however, the boards inside are supposed to flex and give a bit. I suspect that the magnetic strike plattes on the circuit boards are worn and simply need replacing.  will see if i can solve.

    the problem is that when I press one key the other keys are all distorted and make thundering sounds. I have several pianos and they are all doing it. I run a small Music school and live near the sea. Of course I suspect corrosion but don't want to assume anything, just find out what the best way to correct the units is.

It's not really for the faint of heart, but generally this is caused by gunk getting into the key circutry. Underlying the 3000's keyboard is a silicone pad with 2 contacts on it, the measurement between each being hit is the issue usually but yours just sounds like there's something in there causing a physical or contact obstruction.

What you really want to do is to remove the keys and clean everything but this isn't easy... You could try using 99% alcohol (from a pharmacy) to clean inside it which may well help you.

There's a good thread on a similar issue at:

http://www.electronicspoint.com/roland-hp-3000s-digital-piano-dodgy-note-t18946.html

Which may help you work out how to do the disassembly if you are brave, but I would start with pouring some alcohol in and poking it and hoping for the best 1st. It sounds crude, but it works amazingly well with some things.

Several keys don't work at all


This normally indicates dust is present. I don't suppose you own a cat or dog? :) It's amazing what manages to find its way through the gaps! If you're not quite up to diy, send it to your local technician. They'll know exactly what the problem is and with any luck - clean it and assemble it within an hour or so!

Springy keys......is there a way to lesson the intensity of the spring after touch?


In a word, NO. They simulate weighted keys by adding spring force and inertial weights. It gives a more realistic feel, however it is stiffer, more like an acoustic piano. You will develop strength and get used to them... If you have been used to playing some synths that are not hammer weighted these keys will seem very springy.

I Have a Casio Privia Digital Piano and a Roland DP-10 pedal. The pedal function is inverted. When I press it stops the sustain and the effect comes back when I release the pedal. The pedal does not have...


Yep... Roland pedals are reversed, that is, normally closed contacts. Unlike some Yamaha keyboards, the Casio doesn't have an inversion function available. You have two choices to solve this: 1. Buy a pedal with the corect sense 2. Open the Roland pedal and MAYBE with a soldering iron you can move a wire to select a contact with the opposite sense.

Hi, I am undecided about which digital piano to buy: Yamaha Arius 141 or Roland F110? help appreciated, thanks, karol.


I have two Yamaha's and I will say they are maintainable. Almost ALL the weighted piano key models use a keyboard made by one company as I understand it. I can easily get service manuals for the Yamaha, not quite as easy for the Roland... same goes for repair parts. Your decision... listen to each and decide. Hint: Use a set of headphones to do the compparision rather than internal speakers as the orientation in a music store can drastically change the sound.

Need help in choosing the best digital piano you can recommend for me for A budget of 2500-3000 usd


The Korg SV188 has stunning realism in the Grand Piano arena. It uses a 12AX7 tube in the preamp output for that classic analog warmth lacking in so many garden market digital stage pianos these days. It has weighted hammer action and carries a price tag of $1,699.00 at American Musical Supply.com They even throw in a extra years coverage at no cost. The Yamaha MOXF6 88 key (same price) is another fine grand piano that wont disappointed but be prepared for a large learning curve learning all the rest of it functions, there are plenty to chose from. Roland wins hands down with its RD300nx, $1,799.00 and the RD700NX $2,699.00 simply the best digital stage pianos money can buy . Look up the specs at AMS

Does anyone have a parts list for a Roland KR-570 electronic piano? I need to find part numbers for the key-weight actuation mechanism.


Sorry I didn't find you 'til now. I just got the same problem.
If you haven't found out already, Roland has them available from the support dept. (323-890-3740) at $9.00 a piece or $200 for a full set of 88.
They say they've re-designed them to be more durable.

I have around $100 to spend on a used digital piano keyboard, and i know nothing about playing, but i would like to learn, like teach myself, i did at one point try to teach myself on a late 80"s Korg...


You will likely have to double that budget to get anything decent... but look for a Yamaha in the PSR series (61 keys minimum). To get a full 88 key, you might have to be up in the $400 range for anything really decent.

Key won't come back up on Roland digital piano


Roland FP is a nice keyboard but has a known problem on cracking key weights. There is a counter weight under each key to push the key upward. There are two sizes of weight beams, longer one for white keys and shorter one for black keys. Roland did not make the original weight beams strong enough to last. They will crack and eventually break. When it happens, the key will stay down. Fortunately, they can be easily replaced.

Roland FP-8 has 4 black screws at the bottom on each side end. Remove the screws, flip the ends up and expose the interior. Near the hinge of the problematic key, carefully ply open the hinge tabs and remove the key from the hinge. You will find a weight beam under the key. Remove and inspect the weight. There should be a metal wrapped in a plastic beam. If the metal part is missing, find the missing part and replace with a new beam. You can order weight beams from Roland. It costs about $10 each plus shipping. Put everything back in the reversed order.

I need a service manual for Roland FP8 piano, or..


Did you ever get hold of an FP-8 service manual? The weight replacement is relatively simple: The case opens by removal of eight screws, four at each end on the underside. The top then hinges up. Keyboard assembly is removed by first unplugging the two white ribbon connectors at the center, then removing the screws at the front edge (underneath) and the screws (gold) at the back of the assembly (accessible from the top). Keys pop out by spreading the two "wings" at the pivot point, and then the weights (Roland calls them "hammers") lift out. Roland will sell you new ones, but I have no idea whether the replacements are any better than the originals. I've done two of these pianos so far, and have a third waiting to be worked on. I do have a service manual, but I think I downloaded it freebee somewhere.
The other failure mode on this piano is the electolytic coupling caps on the output board - I've replaced all of them on both pianos - don't remember the value offhand.
