Best MIDI Interfaces & Hubs
MIDI interfaces and hubs are the unglamorous connective tissue of a MIDI setup: boxes that turn USB into 5-pin MIDI, merge multiple MIDI sources into one, or let a phone or tablet talk MIDI wirelessly. Nobody buys these for fun, so the buying question is entirely about port count, latency, and whether the box does exactly the one job your rig actually needs.

Frequently asked questions
Do I need a MIDI interface if my keyboard connects by USB?
No, a USB MIDI keyboard talks straight to your computer over the same cable that powers it. Interfaces matter when you have older 5-pin MIDI gear, need to connect multiple hardware devices at once, or want to go wireless.
What is the difference between a MIDI thru box and a merge box?
A thru box copies one MIDI input to multiple outputs, so several synths can receive the same signal. A merge box does the opposite, combining multiple MIDI inputs into a single output, which matters when two controllers need to feed one device.
Is wireless MIDI reliable enough for live use?
Modern Bluetooth MIDI interfaces are stable enough for most live and studio use, with latency low enough that most players cannot feel it. For mission-critical timing-sensitive rigs, a wired connection is still the safer default.
