94 Chapter 4 Setting Up Your System
Connecting Your MIDI Keyboard and Modules
If using a simple MIDI master keyboard, without internal tone generation facilities, you
only need to connect the MIDI Out port of the keyboard to a MIDI In port on your MIDI
interface—using a MIDI cable.
If the keyboard can generate its own sounds, you should also connect the MIDI Out
port of the MIDI interface to the keyboard MIDI In port. If your MIDI interface offers
more than one MIDI output, connect any other tone generators (or other MIDI devices,
such as control surfaces that require bi-directional MIDI communication) to these.
