MIDI I/O (AudioBox iTwo). MIDI stands for "Musical Instrument Digital Interface. "
MIDI inputs and outputs allow connection to, and communication with, external
MIDI equipment. One function of these ports is MIDI sequencing but the MIDI
protocol can be used for much more than instruments and sequencing.
Power User Tip: MIDI is not audio but is frequently used to trigger or control an audio
source (such as synthesizer, keyboard, or sound module). It's important to ensure that your
MIDI data is correctly sent and received by the appropriate hardware or software devices.
If you want to record the audio from the device your MIDI Out is controlling,
you'll need to return the audio to an AudioBox input channel. Please refer to the
documentation provided for your MIDI devices for help with MIDI setup and usage.
Main Outputs. These are the main outputs for your AudioBox interface. The Main
Output knob on the front of the unit controls the volume level of these outputs.
Power User Tip: You must connect speakers or headphones directly to your AudioBox
interface in order to monitor playback from your computer.
