Best Midi Interfaces for tight timing for Cubase?

I have two midex 8s, which have good timing, but for some reason, my ports are disappearing. It’s not because of the midi device setup settings, because I’ve checked. Ports missing in other apps too.

So, I was thinking of replacing them. What other midi interfaces would you recommend? Want tight timing.

iConnectivity makes excellent MIDI interfaces. I have an older model and it has been trouble free, much better the Motu interface I used to use.
