Arturia Rig 16

[Trancer]

I am very interested in the Rig 16.

For the moment my hardware instruments and my three hardware effects (Strymon Bigsky, TimeLine
and Oto Boum) are connected to a Studiolive 32sx and the routing is really simple and functional.

My question is the following.

There are plenty of inputs on the Rig 16, but no auxiliary inputs to connect my three effects.

So if I want to use all three of my effects, I have to sacrifice six Rig 16 inputs.

So not enough inputs on the Rig 16, so I should have completed the Rig 16 with a pre 8 (but no longer available) for my other synths if I understood correctly.

What solution should be planned to have more entries, given that no more manufacturing of the 8 pre?

Will I have to take Berhinger to complete my 8 missing entries?

With the risk that not the same quality.

Can the Rig 16 editor route my three hardware effects to all my synths or to some of my synths as needed?

What solution could be optimal, functional and which could offer me the same routing possibilities as my Studiolive 32sx (synths and effects)?

Thank you in advance for your answer.
