Chapter 5. The Reason Sequencer -- Close Up > The Transport Panel - Pg. 100

The CPU and Audio Clipping LEDs To the far left of the Transport Panel are the CPU and Audio Clipping LEDs. The CPU meter is a real-time indicator of how much of the computer's CPU is being used within a given Reason song. As you begin to accumulate more and more virtual synths, real-time effects, and equalizers within a song, this meter will tell you how much more CPU you have left until your audio "drops out." The Audio Clipping LED is a warning light to alert you when the audio output of Reason is in danger of clipping or distorting. To demonstrate this, open the Reason Tutorial Song and turn up one of the volume faders until you see the clip LED shine a bright red. It is important to keep an eye on this, because you really don't want to clip in the digital domain. Trust me; it sounds terrible! Figure 5.32 shows a graphical example of digital clipping. Figure 5.32 Both of these audio clips were taken from the Reason Tutorial Song. The image on the left is an example of digital audio that is not clipping. The image on the right is an example of digital audio that is clipping. Creating and Managing Tracks Now that you've covered the basics of the Transport Panel, you're ready to move to the left side of Reason's sequencer, called the Track window. This is where all the tracks in a song are created and maintained. If you are not new to the concept of sequencing, this section should look similar to other programs you have used. If you are new to this whole game, you'll be happy to know that understanding this portion of the sequencer is a snap. Creating and Cutting Sequencer Tracks in Reason There are a few ways to create a sequencer track in Reason: A sequencer track is automatically created whenever a Reason synth device is created. You can choose Sequencer Track from the Create pull-down menu. You can right-click (Windows) or Ctrl-click (Mac) anywhere in the sequencer or Device Rack and select Create Sequencer Track.
