iConnectivity mioXL

Extremely flexible interface with lots of options.
Definitely geared towards the pro & semi-pro set-up as it requires a some planning and experimentation when setting up using Auracle software application.
However, iConnectivity site offers plenty of support and videos to guide you.
Highly recommended

Excellent hardware if you have lots of offboard midi connections to manage. I've tried several other options over the past 2 years and nothing comes close (except for the smaller iConnectivity MioXM which I had for a while—it's great too; I just need more connections!).

Sturdy hardware construction; lots of powerful options to route/filter midi messages. The ability to store/recall multiple configurations (say, for stage and studio use) is very helpful.

The control software provided can be a little complex at times, especially if using RTP/Midi, and the documentation is a little thin. But the support team at iConnectivity are very helpful & responsive if you do run into any issues.

If you need the features provided, you'll know; and this product delivers a good solution.

Move on from the old 5-pin DIN cables: CAT-5/CAT-6 ethernet cable is your friend.
I now have 3 of these units and they allow me easily route MIDI clock across my entire studio and connect all synths & drum machines back to my Logic Pro DAW.
The only issue is that the documentation is non-existent even online. You will have to resort to videos and forum posts to set this up for your specific configuration.

Fantastic midi interface. Probably best in business right now.
