Greetings -

I just got a DX7 II D. It is virtually mint.

However, the keys don't trigger any sounds. If I run midi INTO the DX7, I DO get sounds. So the synth itself works, just not the keys.

NONE of the keys work.

Any thoughts? I got this DX7 from a friend who has had it in storage since the 90s. I don't think it's a battery issue, because the sounds are intact. Also, I don't think it's a key membrane issue, because NONE of the keys work.

Any comments or advice?

thanks much Richard
