KL-8™ Owner’s Manual

MIDI IN AND OUT

The KL-8 can send and receive MIDI information over USB, allowing you to use a controller to play a soft-synth 

on your laptop, or record and play back MIDI using a digital audio workstation (DAW) on your computer. The KL-8 

doesn’t generate MIDI information on its own, nor can it be controlled via MIDI; it simply transmits the infomation 

between the 5-pin MIDI and USB connections.

To send MIDI to your DAW to control a soft-synth, connect the MIDI output of your keyboard to the MIDI IN on 

the KL-8 using a standard MIDI 5-pin DIN connector. Please refer to your DAW’s manual for instructions on how 

to set up a MIDI record/playback track or soft-synth. To play back MIDI information from your computer to control 

an external device, connect the MIDI OUT on the KL-8 to the MIDI input on your keyboard or other MIDI-enabled 

device.
