Sequoia includes a professional 4-point editing function. The method is especially effective and intuitive, since it connects the advantages of a linear audio editing studio with those of a non-linear hard disk system.
Two display areas let you view and play back source and destination tracks simultaneously and independently of each other. The lower area of the screen (source) displays the source material, i.e. all of the recorded material and takes.

The upper area displays the target tracks (destination). The cut material is arranged here with the mouse or keyboard. You always retain control of the whole project by being able to navigate in the source material while playback is running in the destination area.
The actual editing takes place via markers. In and out markers in the source indicate the material that should be copied into the destination after a cut command.

This method may be used to quickly realize steps that would otherwise be very time-consuming, e.g. replacement of a passage in a finished multi-track edit with a version that may be played slightly longer. For source/destination, only in/out markers in the source and destination.
The edit command inserts the correct passage and moves the remaining audio material synchronously across all tracks to the new edges of the cut.
