GiO by APOGEE – User’s Guide
Troubleshooting
Symptom -
There’s no signal at GiO’s output.
Solution -
• Verify that the System Preferences Sound windows are
configured as described on page 17.
• If there’s no output after checking the items above, open Audio
MIDI Setup, set Properties For to GiO, and toggle the sample
rate (labelled as Format) from one setting to the other and back.
Symptom -
The input connected to GiO isn’t getting to my audio
application
Solution -
Check that the audio software has been configured to use
GiO for audio inputs and outputs, as described on pages 10-18.
Symptom -
When recording, the input is delayed in my headphones
Solution -
Decrease the I/O buffer size in your audio application.
See page 21 for more information about setting the I/O buffer.
Symptom -
I hear clicks and pops when recording or playing back
from my DAW.
Solution -
Problems with clicks and pops usually indicates that the
I/O buffer in your DAW (audio application) is set too low. Please see
page 19-20 for more information about setting the I/O buffer.
Symptom -
When recording in GarageBand, I can see an input
signal but I can’t hear it.
Solution -
To hear the input signal of a record-enabled track,
Monitoring must be set to On. Double-click a Real Instrument or
Electric Guitar track header to open the Track Info pane, and verify
the Monitoring setting at the bottom of the pane. On an Electric
Guitar track, highlight the guitar amp and click Edit to reveal the
Monitoring menu.
Symptom -
When connecting speakers to GiO, there is hum and/or
buzz at the output.
Solution -
In most cases, a steady hum or buzz at the output is
caused by grounding issues between GiO and the connected
equipment. Because bus-powered USB interfaces are grounded
through the USB and audio connections, and not through a
3-prong grounded AC connection, the situation may arise where
the grounding configuration of the connected equipment must be
modified. Check that the computer is grounded with a 3-prong AC
connection.
Some experimentation may be required to find the grounding
configuration that results in the lowest noise. It may be useful
to disconnect all equipment except GiO, the Mac and a pair of
headphones, and then connect additional equipment one piece
at a time.
Symptom
- GiO doesn’t appear in OS X System Preferences
Solution
-
• Verify that OS X 10.5.8 or later is installed.
• If so, choose About This Mac, then click More Info... to open
System Profiler. In the Contents column, open the Hardware
disclosure triangle and click USB.
• Verify that GiO appears in the USB Device Tree pane.
• If GiO does not appear, try another USB cable or port.
Symptom
- Neither the Transport nor Stompbox switches operate
with GarageBand or Logic Studio.
Solution
-
• Ensure that GiO software and MIDI drivers have been installed
• Verify that the correct version of GarageBand (version 5.1) or
Logic Studio (9) is installed.
