My brother's lent me his old Roland D70, only problem is about 3/4 of the keys don't work! If you have any experience 'under the hood' of a Roland, or can offer helpful advice, please get in touch.

Cheers.

There may be a configuration issue, octaves for instance, or there may be a mechanical or wiring fault.

I know a keyboard roadie who cures such faults with a gentle tap of a rubber mallet.
