You can open the following editing areas directly in the Arrange window by clicking the corresponding button at the bottom of the window.
Mixer
Sample Editor
Piano Roll Editor
Score Editor
Hyper Editor
The Mixer is where you mix your project. Each track is played back through a channel strip. You can adjust the level and pan position of a channel strip, add effects, mute and solo tracks, and send the output of a channel strip to other channel strip types, such as output and auxiliary channel strips.
Full details can be found in the Mixing chapter.
The Sample Editor displays the contents of audio files as waveform graphics. You can use the Sample Editor to precisely edit audio files (and regions). The Sample Editor also features a number of useful destructive processing tools. These allow you to time stretch and pitch shift audio, change sample rates, extract MIDI grooves from the audio, and even quantize audio.
Full details can be found in Editing Audio in the Sample Editor.
The Piano Roll Editor displays MIDI notes as beams on a grid. The piano keyboard to the left is aligned with the note pitches represented by each beam. Note length is indicated by the relative length of each beam. Note position is displayed from left to right—a ruler and vertical grid lines make it easy to see where notes begin and end. Note velocity (how hard a note is struck, and usually how loud) is indicated by color.
Full details can be found in Editing MIDI Events in the Piano Roll Editor.
The Score Editor uses traditional music notation to display the MIDI note events (plus pedal and other event types) of MIDI regions. You can insert and edit MIDI note events in staffs, and use musical symbols to clarify their meaning in this editor. Text, such as lyrics, titles, and comments, can also be integrated into the score. The Print function allows you to print complete scores, with staff numbers only limited by the paper size.
Details on using the Score Editor can be found in Working with Notation.
The Hyper Editor displays MIDI note or controller events as vertical beams, placed along a user-defined time grid. This makes the Hyper Editor the ideal place to:
Add or edit controller data, such as note velocities. It makes some editing tasks—such as data scaling—much faster.
Quickly create and edit MIDI drum parts.
