It is possible, and easy todo:

Let's take the cutoff example:
- first send a page/subpage select to say to the xpander you want to edit a parameter from this page.
F0 10 02 0B 22 00 F7 // Page and subpage select , 22 for VCF/VCA, subpage 0.
- now increment VCF Cutoff as if you were turning the first rotary encoder
F0 10 02 0A 00 18 00 01 00 00 00 F7 // Page edit follows, 18= rotary encoder, 01: increment.
- to decrease the value:
F0 10 02 0A 00 18 00 7F 01 00 00 F7

You can use MIDI-OX and set MIDI Sysex Echo into the Xpander to get all the message when tweaking the parameters.
Just don't forget to send the page/subpage if your parameter is in a different page.
