Symphony64 PCI card – User's Guide
Symptom - Hardware interfaces aren't locking to word clock.
Solution - Check that the PCIe card port is enabled in the Symphony Source drop down menu (Maestro Control
window). Check the PC-32 connection at the PCIe card and at the X-Symphony connector.
Check the word clock cable and master clock source.
Symptom - Because my Symphony system isn't correctly configured, no controls appear in the Maestro Control
window. How can I make settings to correct the issue if they don't appear in Maestro?
Solution - The Clock Source Select and Symphony Source settings are duplicated in the OS X utility Audio
MIDI Setup. Open Audio MIDI Setup (found in Applications > Utilities) and set Properties For to
Symphony 64. The settings Clock Source and Source will then become accessible.
Symptom - I see the following error message on my Mac screen: "No hardware has been detected on
the (primary/secondary) port of Symphony card(s) x."
Solution - If no hardware is indeed connected to the specified card and port, disable the card/port with the Sym
phony Source setting. If an interface is connected but not detected, check the PC-32 connections and
verify that the interface is locked and running at the desired sample rate.
Symptom - I see the following error message on my Mac screen:"The sample rate of hardware connected to
Symphony card(s) x doesn't match the Core Audio rate."
Solution - This message is displayed when the sample rate of hardware doesn't match the sample rate displayed
in Audio MIDI Setup. This error message is most likely to occur when hardware is clocked to an
external clock or an SBus connection has been made on the specified card and port. Verify that the
external clock source is running at the same sample rate as the computer. If the error message occurs
on a card/port with an SBus connection, verify that both computers are running at the same
sample rate.
Symptom - I see the following error message on my Mac screen:"A bus error has occurred on the (primary/sec
ondary) port of Symphony card(s) x."
Solution - This error message indicates that system synchronization has been briefly lost. Carefully check
that all PC-32 connections are completely and firmly inserted. Check that all hardware clock cables
have no intermittant connections by phsically shaking them. Check that the PCI cards are completely
and firmly inserted, and that the PCI bracket is installed. If two cards are installed, check the ribbon
cable that connects the cards. Finally, verify that all hardware interfaces are clocked to one master clock
source.
Symptom - My Maestro configuration (mixer or routing) resets when I re-start the Mac or change sample rate.
Solution - To load your Maestro configuration automatically when starting your Mac: 1) create the desired
Maestro configuration and save it 2) drag the saved file icon into the Dock 3) Control-click the icon,
and check the "Open at Login" item.
