Help: My RD-700 has become uneven

[trazom]

A little over 3 years ago I purchased a slightly used Roland RD-700. It sounded/responded absolutely fantastic for some time.

After a while I began to notice that the keyboard seemed to be uneven. It was very slight however, and I considered the possibility that I might be imagining it.

But it has gradually gotten worse and worse, and now there is no question that it is uneven. In particular the mid-range of notes is less controllable. Middle C often sticks out, and most of all the A above it. The A stands out quite harshly... striking the key with the velocity that would produce perhaps a mp-volumed sound on another note ends up being a painful FF!

The unevenness and this A in particular have made it so I can hardly stand playing the thing! I only use it to simulate an acoustic (I'm a classical pianist  ). I know I should just get a real acoustic but I can't currently due to financial/space reasons.

I have been searching but can't find any info on this. I hadn't realized the digitals would require maintenance from regular and careful use.

I don't have much extra money at the moment, so I don't think I can afford to have it serviced... and purchasing a new instrument is currently out of the question.

So..... Does anyone have any Do-It-Yourself advice to fix this? Though I can't afford servicing, I could probably afford ordering some small replacement parts (such as contacts or whatever's in there) if they're not too expensive.

My friend and I are pretty smart and have opened up and fixed laptops and things, soldering in replacements parts.

But I have no clue what's going on inside this Roland and if there's an intuitive and cheap way to fix this uneveness.

Any advice?

I hadn't realized the digitals would require maintenance from regular and careful use.

Considering how unreliable most household appliances are (e.g. I just scrapped an otherwise rather good, quite upmarket, cordless phone because the buttons are packing up) I reckon most keyboards do pretty well. I must admit I've never seen that particular fault before and I can't think offhand what's causing it, though it's clearly down to whatever senses key velocity inside there.

Any digital piano under heavy play will need a new keyboard. I think that is your issue.

You can call Roland at 323 890-3700 or call a local MI store that does keyboard repair.

Good Luck,
