2.3 Connecting 12 Step
The 12 Step can talk to computers and tablets via USB, and MIDI hardware via MIDI cables (KMI MIDI
Expander required). Both methods can be used independently or simultaneously.
2.3.1 To A Computer
Connecting the 12 Step to a computer requires three things: a 12 Step, a computer, and a USB A to
USB B cable (the “classic” USB cable). Simply plug the 12 Step’s main USB port into a USB 2.0 (or
greater) port on the computer. The 12 Step will receive power from the computer.
Note : The 12 Step can also be used with a USB hub connected to a computer. It is highly recommended
to use a powered USB hub, not a bus-powered hub. Bus-powered hubs may not be able to provide enough
power to the 12 Step to function properly.
