Note: In some cases, audio input ports number 17 and number 18
on your computer may show a port name such as “ZERO
INVALID AUDIO1, INVALID AUDIO2” or “INPUT17,
INPUT18.” These audio input ports are invalid, and cannot
be used.

may display its own port name rather than obtaining the

by using System Setup or the ZERO Edit application.
MIDI connections
In order to send and receive MIDI messages via the MIDI connectors, you
will need to obtain commercially-available MIDI cables. Connect these
cables between the ZERO4’s MIDI connectors and the MIDI connectors of
your external MIDI device.
MIDI IN connector: This receives MIDI messages from another MIDI device.
Connect it to the MIDI OUT connector of your external device.
MIDI OUT connector: This transmits MIDI messages from the ZERO4. Con-
nect it to the MIDI IN connector of your external device.
