The input and output channels from my 2nd Symphony I/O module don’t show up

If you have installed a 2nd i/o module in your Symphony I/O and the input and output channels are not showing up in Apogee Maestro or in your DAW, there are a few things to check:

1. First, launch “Apogee Maestro 2” from your Applications folder. Go to the “Input Routing” and “Output Routing” tabs. Click the “Reset Routing” button in each of these tabs. Do the channels for the 2nd module show up now? If so, the issue is now resolved and you can ignore the rest of this post. If not, proceed to the next steps.

2. With your Symphony I/O connected to your Mac via USB, launch the “Symphony I/O Firmware Updater” app from Applications> Utilities. Check to see that all the versions are current. If it gives you the option to update, then update by following the instructions in this link: Updating firmware. If it only gives the options to “force-update” or “quit”, then confirm that the version for the “secondary i/o module” actually shows up and does NOT show “N.A.” or “0”. If it is showing the firmware version properly, quit the updater. If it shows “N.A.” or “0”, then quit the updater and proceed to the next step. Do not force-update.

3. You may need to confirm that the 2nd i/o module is connected properly to the Main board. If you feel confident opening up the unit, proceed with the instructions. If not, you will need to have an Apogee dealer do this or send it in for a repair.

Instructions for checking ribbon cable

Unplug power from SymI/O

Remove screws and lid from SymI/O chassis

Gently pull up a little with your thumbs on each side of the ribbon cable connecting the i/o module to the Main board until you’re able to pull the ribbon cable out. Do this to both ends of the ribbon cable and remove it from the connector.

Please note whether the ribbon cable is gray or black. If it is black, you will need to contact our Tech Support and request a gray ribbon cable.

If the ribbon cable is gray, carefully set the ribbon cable back into place, making sure to line up with the pins in the connector. Gently push on each end until the ribbon cable is FIRMLY in place… if it’s not pushed down all the way, the boards won’t power up correctly.

Put lid back on chassis and plug power back into unit.

Once the unit is powered up, launch “Apogee Maestro 2” from your Applications folder and click “Reset Routing” in both the “Input Routing” and “Output Routing” tabs.

Why are the input and output level/volume popup indicators not showing up?

Several Apogee products have pop-up level indicator graphics that will appear on the desktop of your Mac when the input and output levels are adjusted from the device or from the Mac’s keyboard volume buttons.


If the pop-ups aren’t appearing, there are a few things to check:

Launch ‘Apogee Maestro 2’ from your Applications folder, click on the ‘Apogee Maestro 2’ drop-down desktop menu and select ‘Preferences’. Confirm that the ‘Display pop-ups’ checkbox is checked. If you don’t see this option, then pop-ups aren’t available for the product you’re using.


If you’ve confirmed that the ‘Display pop-ups’ checkbox is checked and you’re still not getting the pop-ups, try the following:


– Unplug/replug your Apogee device

– Restart your Mac

– Launch ‘Activity Monitor’ (Applications> Utilities> ‘Activity Monitor’), click the ‘View’ drop-down desktop menu and select ‘All Processes’. Type ‘apogeepopup’ in the searchbar in the upper right-side corner of Activity Monitor. Once you see ‘ApogeePopup’ displayed in the list, highlight it and force-quit the process by clicking the ‘X’ button in the upper left-side corner of Activity Monitor. Wait a few seconds and you should see the popups again after adjusting input/output level.


*Note for Duet Firewire and Ensemble Firewire customers*

There was a known issue with pop-ups not working for Duet Firewire and Ensemble Firewire when using any version of Mac OS 10.8. It is recommended that you use either a version of Mac OS earlier than 10.8 or later than 10.9.



Apogee Maestro crashes when I launch it

If Apogee Maestro 2 is crashing every time you try to launch it, follow the steps below:

– Go to your Applications folder and locate the ‘Apogee Maestro 2’ icon.

– In the ‘Get Info’ window, check the ‘Open in 32-bit mode’ checkbox.

– Close the Get Info window and relaunch Apogee Maestro.

One for iPad & Mac: After changing AA batteries ONE is not seen

If the unit remains connected to your iPad, iPhone, or iPod Touch while changing batteries, then you will need to disconnect the ONE from the iPad and reconnect for it to show up.

Apogee recommends either plugging in the AC while changing AA batteries or disconnecting the ONE from the iPad then changing batteries.
