Step-by-step explanation:
The best view for recording long parts and organizing the form of your track in a music production software is the arrangement view.
In the arrangement view, you can easily arrange and organize different sections of your track such as verses, choruses, and bridges. It provides a linear timeline where you can drag and drop audio and MIDI clips to create the desired structure and flow of your track.
