Nektar Midiflex 4 4 port Flexible MIDI Interface

The Nektar MIDIFLEX 4 USB MIDI interface provides flexible MIDI ports for any MIDI setup on macOS, Windows or iOS. The 4 MIDI ports can be configured as 1 in / 3 out, 2 in / 2 out, or 4 out interfaces - and if you need even more ports, simply plug in another MIDIFLEX 4 to expand your MIDI power!
ALL THE RIGHT PORTS, RIGHT NOW.

No driver required: the MIDIFLEX 4 is USB-compatible, meaning setup is virtually instantaneous! Simply plug the MIDIFLEX 4 into your computer and the ports become available in your DAW software's MIDI settings.

Automatic Port Detection: Even better, MIDIFLEX 4 automatically detects whether a MIDI input or output is connected and indicates the setting with its MIDI port LEDs. So just connect your external MIDI devices and let MIDIFLEX do the rest. The 4 LEDs indicate whether a port is configured as In or Output.

Expand your ports with multiple devices: We know it's never enough - if you need more ports, just plug in another MIDIFLEX 4 to get more ports!  For example, with 3 MIDIFLEX 4s, you can build a system with 4 MIDI ins and 8 MIDI outs!
 
And if that's still not enough, you can always add another one...
