An often used technique in music production to spice up a song is to reverse a sound. Commonly used in Electronic forms of Dance music is a reversed Crash Cymbal which can be a great way to lead in to a main section of a song and create excitement and build tension before the beat begins. You may also hear reversed guitars in popular rock and psychedelic rock tunes. In fact virtually any musical form can benefit from the occasional reversed sound. Logic makes it easy to achieve this, but there are a couple of important steps to bear in mind. So let's jump straight in to this Quick Tip and explore how to reverse a sound or melody in Logic!
I've used a Green Apple Loop: African River Kalimba 01 for this tip. You can choose any loop. Here's what it sounds like:
We want to reverse the sound of this loop (which is currently a MIDI Region). So, we need to convert the MIDI regions into an Audio Region. Bounce in Place is probably the quickest way to do this.
Select the region and choose: Region > Bounce in Place
From the Bounce in Place Options I'm choosing:
Even if you're working with an audio region to begin with I would recommend either copying the original audio file and/or bouncing it to a new audio file, because reversing audio in Logic is a destructive process and will permanently alter the audio file.
Logic will calculate the samples of the audio region and immediately reverse the contents of the original file permanently. The region display will be updated in the Arrange area.
But please remember, I did say 'reverse', 'original' and 'permanently' in the same sentence! In case you skipped reading that part at the end of Step 2, now is a good time to undo (Command+Z) and choose Audio File > Save a Copy as... before continuing! Do bear in mind that many of the functions in the Sample Editor are destructive and will permanently change the audio file you process!
So here's what our reversed region sounds like:
It might go well in a fill, or an alternate chorus, or panned far right/left or cut up and left subtly in the mix somewhere... You decide. Reversing audio is one case where going backwards can take your music forwards...!
