Verify that your monitors' audio signal runs through an amplifier or you have powered monitors connected to the Monitor Outputs of the Digi 001 interface. Verify that the Monitor Mode button on the front of the Digi 001 is NOT depressed (for more information on monitor mode, refer to page 40 of your "Getting Started with Digi 001" Manual).If the I/O labels on your track I/O buttons do not match your Digi 001 interface or specify "no interface", you need to set your I/O setups dialog to the factory default. Go to Setups > I/O Setup and choose the Input tab. Click on the Default button to reset your inputs to their factory designation. Continue through the Outputs, Insert and Bus tabs and click the Default button on each page.
