Connect an audio interface to your computer. The method for doing so varies according to the make and model of audio interface, but you typically use either a FireWire or USB cable. An audio interface serves as an audio input, sound card and mixer for your computer. They enable you to route audio directly to a software application, such as FL 9.
Connect a 1/4-inch jack cable to your guitar. Connect the other end of this cable to the “Input” jack on the front of the audio interface. Play the guitar as loud as you intend to record. If the red light on the front of the audio interface flashes, turn down the “Gain” dial to reduce the strength of the input signal.
Double-click the “FL 9” desktop icon to launch the program. It may take a few seconds for the program to load fully.
Click on an empty mixer track to highlight it. Click “Shift” and “E.” This loads “Edison.” This is the native audio loop-slicer plugin. With it you can record audio segments from an external source, such as guitar via an audio interface.
Click the “In” window in the top-right of the Edison interface to assign the connected external input source, namely the audio interface, to the mixer track in FL 9. If you don’t do this, nothing will record when you start. Also, it’s essential that you select the input device after you’ve loaded Edison into a mixer channel, otherwise Edison won’t record.
Click on any of the “Auxiliary” tabs on the right-hand side of the Edison interface to assign effects to the guitar recording.
