In general, you can *refer* to another company's trademark, but you
can't *use* their trademark in a competing way (see below).


That's how I understand it, but Yamaha are very particular about syntax.
That's why I'm asking them directly, because that way I might get two things:
better clarification (because their web page details use of 'YAMAHA', but not
of 'DX7'), and perhaps even some slack (as written permission) regarding
their usual rules, if they decide my use is not in conflict, but co-
operation, which it is, being essentially a matter of interoperability. When
I make my own synthesiser ideas public, beyond emulation of theirs, it will
have its own name, which is already chosen, unless I think of a better one.

If you have a question about the exact nature of the trademark, go to
the USPTO and see who has a trademark on DX7. They have a search on
their web site. Not as easy to use as google, but it does work. Yamaha
has no more claim to the trademark than what is registered.

I did a quick search and found nothing. I did get hits on RX7 though,
so I was using it correctly. Looks like DX7 is not trademarked in the
US at least. You'll have to figure out how to do the search in the EU.
