“Bus Error” when using Symphony64 PCI card or Symphony64|ThunderBridge

Bus Error is a message that will appear in the Apogee Maestro 2 window under the System Status section. This is typically a communication issue between the connected device, and the Symphony64 or Symphony64|Thunderbridge.

This can be caused by several things:

  1. A common cause for this is that the port setting in Audio MIDI Setup (Applications>Utilities) is set to Ports 1-2, when only one port is actually being used.

  2. A bad PC32 cable (DigiLink)

  3. If using a Symphony I/O, the AIM setting could be incorrectly set to “USB Audio”, “Standalone”, or “Pro Tools HD”, instead of the “Symphony” setting.

  4. Connecting a single device to Port 2 (17-32), instead of Port 1 (1-32)

If only one device is connected and you are receiving the Bus Error message in the system status window in Maestro, please revert back to the Port 1 (32 channels) setting in Audio MIDI Setup. You may need to reboot your computer for the new setting to take place. Secondly, ensure by pressing and holding the right-hand encoder knob on the front panel of SymphonyIO, you are in fact in “Symphony” mode.

Symphony Audio Interface Mode

Requirements to connect Symphony I/O to Apogee Symphony 64 or Mobile PCI cards:

  • Apogee Symphony 64 Thunderbridge or Symphony 64 PCIe card (sold separately)
  • OS X 10.8.5, 10.9.5, and 10.10 and higher (64-bit and 32-bit kernel modes)
  • 2GB memory required, 4 GB recommended

 

Pro Tools HD Audio Interface Mode

A Symphony I/O based Pro Tools system consists of two independent computer connections: audio (to a Pro Tools HD PCI card) and software control (via USB to an Intel Mac running Maestro 2). In the case where PCI cards are installed in a PowerPC Mac or Windows computer, it’s possible to run Maestro from a separate Intel Mac, such as Mac Mini or MacBook.

Note:

Running Symphony I/O in Pro Tools HD mode on a PowerPC Mac requires an older firmware version. You can request this older firmware by emailing: betafeedback@apogeedigital.com. Only the 8×8, 16 Analog In/Digital Out, and 16 Digital In/Analog Out modules are compatible with versions of Pro Tools HD older than version 9. The 16×16 Analog In/Out and 2×6 modules are only compatible with Pro Tools HD versions 9 and above.

 

Requirements to connect Symphony I/O to Avid Pro Tools PCI Cards:

  • Avid Pro Tools HDX, HD Native or HD Core/Accel/Process card installed in a computer in accordance with the Pro Tools HD Compatibility Grids, available at www.avid.com
  • Pro Tools 8.1 (requires older Symphony I/O firmware), 9.0 or greater, 10.0 or greater, 11.0 or greater

Requirements to run Apogee Maestro software, to control Symphony I/O via USB:

  • OS X 10.8.5, 10.9.5, and 10.10 and higher (64-bit and 32-bit kernel modes)
  • Apple Intel Mac

USB Audio Interface Mode

 

Requirements to connect Symphony I/O as a USB audio interface:

  • OS X 10.8.5, 10.9.5, and 10.10 and higher (64-bit and 32-bit kernel modes)
