NRPN hell :)

[jojogib]

Im trying to control th fx unit via NRPN.
It works when I turn the algorithm wheel first for instance to chorus and I can change the parameter.
When i turn the algorithm wheel to delay i can change with the same NRPN the values there.
How do i manage to send the algorithm parameter for (reverb delay) first and then the parameter in this category?

like:
chorus parameter 1
or delay parameter 1
