Ensemble: General

Is it ok to leave my Apogee device plugged in and connected to Mac?

Yes, it is perfectly fine for any of our devices to remain plugged in and connected to your Mac (or iOS device). There is no harm in the device remaining powered up while you’re not using it.

What is the ‘A button’ (device ID) in Maestro for?

Most Apogee products that use the Apogee Maestro 2 control application will include a ‘Device ID’ button that can be found in multiple Maestro tabs under a graphical icon for the connected Apogee device. You will usually see this button as an ‘A’.

Here is an example of what it looks like when you have a Symphony I/O connected:



The purpose of this button is to quickly identify which Apogee device you’re adjusting parameters in Maestro for. When you click on the button, it will light up the front-panel of the corresponding Apogee device so you can see which device you are adjusting parameters in Maestro for. Click the button again and the device will no longer be identified.

Since multiple Apogee devices can be connected and appear in Maestro at the same time, it can sometimes be confusing to know which device you’re adjusting parameters for. Having more than one Duet or Quartet connected to a Mac may not be as common as having multiple Symphony I/Os or Ensembles connected, but the ‘Device ID’ buttons are there for each product, just in case.


A typical use-case:

You have 2 Symphony I/Os connected to one Mac and both are showing up in Apogee Maestro. You can go to the ‘Device Settings’ tab in Maestro and change the peripheral prefix of the 2nd Symphony I/O to ‘B’ (or any other letter you want). Now, when you click the ‘B’ button (Device ID) in Maestro, the 2nd Symphony I/O will become identified.  If you click the ‘A’ button, the 1st Symphony I/O will become identified.


How do I know what version of Maestro is installed on my Mac?

To find out what version of Maestro you have installed:
  • Open Maestro 2 (found in your Mac’s application folder) and click on the “Apogee Maestro 2″ menu in the upper left-hand corner of the desktop menu bar
  • select “About Maestro 2″. This will bring up a window showing you which version you have installed (see example below)

Does the Apple Thunderbolt to FireWire adapter work with Ensemble?

Yes:  The Apple Thunderbolt to FireWire adapter works with Ensemble Firewire and the current Ensemble FW software release, found on Apogee’s website. There is no noticeable difference in quality or performance from using a built in FireWire port.

Note: This does not apply to Ensemble Thunderbolt. This adapter cannot be used to add Thunderbolt to a Firewire computer. You simply cannot use Ensemble Thunderbolt with a non-thunderbolt Mac.

Is Ensemble compatible with Mac OS X Mountain Lion (10.8)?

Yes! Ensemble is fully compatible with Mac OS Mountain Lion (10.8). If Ensemble February 2012 software was pre-installed before updating to OS X 10.8 Mountain Lion, it is not necessary to install any new Ensemble software.


The Ensemble July 2012 release is intended for first time Ensemble installations on Mac OS X 10.7 Lion and 10.8 Mountain Lion

I hear a delay between what I play and what I hear in my monitors. Can I do anything about this?

This delay is called latency, and is caused by your computer and/or recording software.

Using the low latency mixer found in the Apogee Maestro 2 application may help. Click on the mixer tab to configure it to your desired settings. Be sure to set your desired output to “mixer” on the output page.

Ensemble’s status LED

The Ensemble’s status LED should be solid blue if you are using it in standard mode and solid green if you are using it in standalone mode.


The possible status LED indications are as follows:

• A solid blue LED indicates that Ensemble is locked to the clock source chosen in software control and that the Firewire connection is valid.

• A green LED indicates that no Firewire connection is present, and that Ensemble is operating in Stand-Alone mode.

• A flashing LED indicates that Ensemble is not locked to the selected clock source.

• A red Status LED indicates that Ensemble has not achieved a valid Firewire connection. After a few moments Ensemble will switch to Stand-Alone mode.

• A flashing red LED indicates that both error conditions are present.
