For accuracy in the mapping of species....
...this is being moved to the forbes vs nigricornis page. These two species cannot be determined from one another on photos. Both Forbes' and Black-horned can have a great deal of black on the antennae, head, pronotum and limbs.

From previous work by a researcher who collected and recorded the song of many individuals throughout many states, it is generally accepted that Forbes' occurs west of Ohio and Black-horned occurs east of Ohio. Both species occur in Ohio.

States close to Ohio are difficult for identification to species.

Tree Cricket
looks a lot like this Black-horned Tree Cricket (below) but wait for more expert opinion

Black Horned Tree Cricket
would be my guess.

I agree, Black-horned Tree Cricket
While for many species one can rely on antennal markings for an ID, the overall color, the black limbs and pronotum, the black antennae, and the browish head put this TC in the nigricornis group. There is a chance it could be a Forbes' TC, but they are only ID'd by the singing of the male in certain temperatures. Although you mention this TC was making a lot of noise...this is a female. Thus, it would have been a nearby suitor making the noise. The females wings wrap around the body; the males wings are paddle shaped and lay atop the body.

yes I saw the wings and they
yes I saw the wings and they wrap around. So it had to be female
