NanoHUB compatability with Korg PadKONTROL and Radium 49

[Dylan]

I'm writing to inquire about the compatibility of the KORG NanoHUB with non-nano products. I'm considering purchasing the Novation MkII and was wondering if the NanoHUB was compatible with the MkII, a PadKONTROL, and a Radium 49. The KORG site says the NanoHUB is made for the nano series but will it work with any MIDI Controller?

Thank you very much if you can help.
