Yamaha Genos external instrument issue

Hello.
I have an Yamaha Genos routed to Cubase 11 pro via Focusrite Scarlett 8i6 as an external instrument - cables are all correctly connected and I have had some success witn recording, though there are some problems i would appreciate any help you might be able to provide.
Whtever voices the Genos came with, I can record these voices fine via midi in Cubase. The only issue is that specifically the FX that the voice is presented with in the Genos, is not retained in playback through Cubase. Recording the *default voices and playing them back is not an issue generally - aside from that caveat.
The main problem is, Yamaha has certain expansion voices for the Genos available on their website, which I downloaded and installed on my instrument. I would like to record these expansion voices, but the patch script for the Genos in Cubase does not have them and they cannot be selected and thus, they cannot be recorded.
What do I do in order to make these expansion voices available to be selected within Cubase so that they are recorded? Are there any extended patch scripts available/how does one make a new one?

To summarize, the recorded voices have no effects on them during playback, and expansion voices cannot be recorded at all since they arent visible in the patch list for Genos in Cubase.
Thank you in advance.

I assume you are using the MSB LSB implementation of the Yamaha Genos.
Do these additional voices concern Super Articulation 2 ?

I have an old clavinova CVP303
and I had to modify an existing midi patchname file
to configure it for my keyboard

No I think it must be the superior pack

In this case if it is not in the already existing files you will have to create them with a copy to modify in word for example
