MIDI interfaces connect 5-pin and TRS MIDI instruments to computers and route MIDI between devices. Our range holds 25 MIDI interfaces and tools from 16 brands.
When you need one
Most modern controllers connect over USB, but many synths and drum machines only have 5-pin DIN or TRS MIDI. A MIDI interface bridges those to your computer. As soon as you have more than two or three hardware instruments, a multi-port interface keeps everything connected without replugging.
Hubs, thru boxes and USB hosts
MIDI thru boxes split one MIDI signal to several instruments
USB host devices connect USB-MIDI controllers to hardware synths without a computer
Merge boxes combine two MIDI sources into one
MIDI-to-CV converters drive modular and analog synths from MIDI
Timing
Dedicated interfaces with good drivers give tighter timing than chained thru ports. For clock-sensitive setups, keep chains short.
Before you buy
Count your 5-pin and TRS MIDI devices
Choose enough in and out ports
Check TRS type A or type B compatibility
Consider a USB host if you want to work without a computer
Check MIDI-to-CV if you use modular
Frequently asked questions
Do I need a MIDI interface for a USB keyboard?
No. USB-MIDI keyboards connect straight to the computer.
What is the difference between MIDI thru and MIDI out?
MIDI out sends what the device itself generates; MIDI thru copies what arrives at its input.
Can I connect a USB controller to a synth without a computer?
