Not sure if you mentioned budget at all. So I will just recommend away
An Antelope Orion 32+ has 32 ins.
A Presonus Quantum 4848 also gives you 32 inputs at half the price of the Antelope Orion.
Alternatively you could get an interface that has 2xADAT in/outs (eg a UAD Apollo x6 or 8) and get two Behringer ADA8200s which would give you a total of 8+8+8 = 24 hardware inputs… with an Apollo that wouldn’t be too cost effective, but I’m sure there are cheaper interfaces out there.
OR Alternatively you could chain up two or three UAD Apollos via Thunderbolt.
Digital Mixers are also great (Presonus, Allen & Heath, Behringer x32) but they do usually have quite a footprint space-wise and the fewest support ADAT which is really annoying when it comes to expanding ins/outs.
