Launch Melodyne. Click "File," then "Open." Navigate to and double-click the audio file you want to work with.
Click "Algorithm," then select either "Melodic" or "Polyphonic," depending on the audio.
Click the "View" menu, then click "Show Note Separations." Melodyne displays the separations between notes as vertical lines.
Move the cursor over the line separating the two notes you want to connect. The cursor changes to the Note Separation Tool.
Double-click the note separator to remove it and connect the two separated notes. Repeat the process for any other notes that you want to connect. Click "File," then "Save" to save the altered audio.
