This is a broad question that entails a lot of explaining how midi works.
A clock is just a pulse in most cases. You’ll need to understand how your intended clock source outputs this via midi. IE: what channel and CC is it using. Once you know this you can be sure you are selecting the correct Midi module output on the SSP.
For CV, this is the same basic idea. using the input module you would select the input on the SSP you have your clock signal coming into, and then would route that to your step sequencer modules clock input.
To go into depth here would be a very long post, and would be fraught with a bunch of back and forth.
From what I’ve just said, try to give me specifics to answer and that might be a more productive way of trying to help you.
I will admit up front that while I understand how midi works at the implementation level, that I am not a skilled user of it in practice.
