Midi setup for keystep pro, QY10 and cubase

Hello everyone,

I’m the proud recent owner of a Chroma, and I’ve connected it (not without difficulty, thanks to Steinberg) to Cubase.
I use it for 4 VSTs without any problems.
But I found a QY10 in my boxes.

First question: is the KSP capable of doing this?
Second question: have any of you tried this? (with a QY or other midi hardware sequencer)

Below is a diagram to summarise…
