Symphony64 PCI card – User’s Guide
Maestro Control Window
Settings Pane
Apogee’s Maestro software provides control, routing and low latency mixing functionality for the
Symphony 64 system. The application consists of two windows, Maestro Control and Maestro Mixer.
Interface Drop Down Menu – The Interface drop down menu, found in the upper left corner of each Mae-
stro window, is used to select the Apogee interface whose settings are displayed in the Maestro window.
Details of the Interface drop down menu are shown below:
Identify Unit – This feature is disabled when interfaces connected via Symphony PCIe are selected.
Clock Source Select (This setting is duplicated in Audio MIDI Setup as Clock Source) - This drop down
menu is used to set the clock source of the rst hardware interface connected to the Master PCI card’s
Channels 1-32 port. When set to Internal, the selected interface derives clock from an internal crystal;
when set to External, clock source selection varies with each Apogee interface, as described below.
Rosetta 800/200 – When set to External, the specic source (ADAT/SMUX, AES or WC input) must
be manually selected on the Rosetta’s front panel.
AD-16X – When set to External, the AD-16X accepts clock from its Word Clock input.
DA-16X – When set to External, the specic source (WC or Input) must be manually selected on the
DA-16X’s front panel.
If any other interface but the rst is selected in the Interface drop down menu, this setting will be greyed out.
Symphony Source (This setting is duplicated in Audio MIDI Setup as Source) - This drop down menu
selects PCIe card ports to be enabled for use. Ports that have a PC-32 connection to hardware interfaces
or another Mac should be enabled, while unconnected ports should NOT be enabled.
If only port 1 is used, set Symphony Source to PCI Card 1, Port 1 (CHANNELS 1-32)
If ports 1 and 2 are used, set Symphony Source to PCI Card 1, Port 1-2 (CHANNELS 1-64)
If ports 1,2 and 3 are used, set Symphony Source to PCI Cards 1-2, Port 1-3 (CHANNELS 1-96)
If ports 1,2,3 and 4 are used, set Symphony Source to PCI Cards 1-2, Port 1-4 (CHANNELS 1-128)
For space considerations, the ports are numbered 1 to 4 in the Symphony Source drop down menu.
Figure C, shown on page 9, indicates the number assigned to each port.
If an unconnected port is enabled, no interfaces will appear in Maestro. Make sure that all enabled port
have a PC-32 connection to an interface or another Symphony-equipped Mac.
