DUET-FW INTERMITTENT CRACKLING / POPPING / NOISE / DISTORTION

Temporarily turn-off/disable Airport, Bluetooth and wireless networking features to verify whether this affects the issue. Also try adjusting your I/O Buffer Size. Only install Maestro Software when the Duet-Firewire device is the only peripheral/external device connected to your Mac. Disconnect any external devices to ensure proper testing and troubleshooting for intermittent noise.
