Symphony64 PCI card – User's Guide
Let's look at a specific example of a Symphony system consisting of two AD-16Xs, two DA-16Xs, 1 Mac Pro and 1
MacBook Pro.
As shown at right, the required PC-32 connections are 1) from the hardware interfaces to the Mac Pro's Sympho-
ny 64 Channels 1-32 port and 2) from the MacBook Pro's Symphony Mobile card to the Mac Pro's Symphony 64
Channels 33-64 port.
Settings are especially crucial when configuring a multi-Mac system:
• Ensure that the sample rate of both Macs is the same.
• Set Symphony Source on the Mac Pro to Ports 1-2.
Note: the Symphony Source setting is fixed on the MacBook Pro, as there is only one port available.
As shown in the routing diagram at right, the hardware interfaces' inputs and outputs are routed to the Mac Pro's
software inputs and outputs 1-32, and the MacBook Pro's software inputs and outputs 1-32 are routed to the Mac
Pro's inputs and outputs 33-64.
Provided you've set your software to use the Symphony driver's input and output labels, the Mac Pro's 33-64
inputs and outputs are labelled SBus In/Out 1-32. This makes routing signals between the Mac Pro and MacBook
Pro as easy as choosing SBus Out 1-2 on one computer and SBus In 1-2 on the second computer.
To illustrate the simplicity of routing between Macs, here are the steps required to route a Logic software instru-
ment running on the MacBook Pro into an auxiliary track's input on the Mac Pro:
• In the Logic session running on the MacBook Pro, set the software instrument's output to SBus 1-2.
Because no hardware is connected to the MacBook Pro, only SBus inputs and outputs are available.
• In the Logic session running on the Mac Pro, create an auxiliary track (Options > "Create New Auxiliary
Channel Strip" in the Mixer window) and set its input to SBus 1-2 and the output to SymOut 1-2. Now, the software
instrument's output is routed to the audio track's input and then routed to the DA-16X hardware output 1-2.
