Hey Jeff, good to see you back here. I have both Epidendrums and Dendrobiums that put out roots from the stems. Not sure about the Dens growing in soil, but the Epi's certainly will.
On the other hand, the Dens are more likely to have purple flowers than the Epi's.
I don't know what your cuttings may be, but I would tend to lay them horizontally on some very loose potting mix with lots of perlite in it, keep them in bright shade and mist often until you see some roots emerging.
