Now that you've looked closely at a track of music in Reason, let's go deeper and get a glimpse into one of Reason's most powerful features: control over instruments.
You can actually record nearly any movement of any knob, lever, or button on a Rack device. The movements are stored in the instrument's Sequencer track and then get sent to the Rack during playback. If you want to see what controller information looks like in a track, you must first tell Reason to display it.
