adjacent \Ad*ja"cent\, a. [L. adjacens, -centis, p. pr. of adjacere to
lie near; ad + jac[=e]re to lie: cf. F. adjacent.] Lying near, close, or
contiguous; neighboring; bordering on; as, a field adjacent to the
highway. ``The adjacent forest.'' --B. Jonson.
Usage: Adjacent, Adjoining, Contiguous. Things are adjacent when they
lie close each other, not necessary in actual contact; as, adjacent
fields, adjacent villages, etc.
...
So this patent doesn't cover a control line lying over the waveform.
Just incase there is a photo in Road's "Computer Music Tutorial" of
someone editing control points associated with a waveform (with a lightpen
or something). The photo was '70's IIRC, certainly earlier than 1989.
Don't have a copy to hand, so I can't look up the page number, but if
anyone cares I'll nip over to the library tommorow and scan it.
