Can Cubase Rewire to an older version of itself?

I don’t use rewire, so this is ENTIRELY SPECULATION :open_mouth:

I know it works fine to run 2 different versions of Cubase simultaneously, e.g. Cubase 10 & Cubase 8.

I wonder if these could then be rewired to each other? If so then it seems possible to use an old 32-bit version of Cubase to natively host 32-bit plugins.

or not

Never tried, but I don’t think you can.
Something with Cubase always want to be the master and not the slave.
But you should be able to do it with Reaper, that is pretty lightweight as a added bonus.
