Overgrown Crucifix Epidendrum Radicans

[Dr. Dave 4u]

Hello again!

I believe I have let my Crucifix Epidendrum Radicans get overgrown. I had it outside this summer and it was very happy and bloomed beautifully. But now its almost taller than my window frame and falling over.
It doesn't seem to be making keikis.
Can I just cut it off half way and seal the cuts with cinnamon?
Will the trimmed sections also grow?
As you can see in the pic its put out tons of aerial roots.

Anyone with experience growing this?
Your help is greatly appreciated...
