If you want to bring (Import) an MP3 or Audio file into CUBASE and analyze it for learning/teaching or
Simply reusing it for a song or track you are composing – Here is how you do it…

For example, if you want to be able to slow down (tempo wise – without changing the pitch) an audio track so that you can figure out what is being played and examine the arrangement or simply use it as a loop, read on…
Although you could technically do this to an entire song (3 minutes +) it’s better to break the song/track up into separate 4 BAR segments. This is because all of the TEMPO/TIME stretching – compressing capabilities of CUBASE are based on the idea of working with “small” 1-4 Bar loops.
So, the first thing to do is define “LOOPS” or small segments of the song/track for processing.
To start, we will define a 4 bar area or “loop” that we want to examine.
To do this we want to set the LEFT / RIGHT boundary (or the start and end of the loop) markers in Cubase… Remember at this point the TEMPO that is set in Cubase has no relationship to the audio
you have just imported since the DEFAULT tempo of a new project in Cubase is 120 Beats Per Minute or 120 BPM. IE: Cubase has NO idea and does NOT care if the audio you just imported has ANY tempo value of any kind.

NOTE: To set (adjust) the Left and Right “markers” – Set LEFT Marker by holding down the “Ctrl” key
And clicking (and sliding) in the RULER area – Set RIGHT Marker by holding down the “Alt” key and
clicking (and sliding) in the RULER area.
After setting the L & R “Markers we can preview the “LOOP” by clicking on the “LOOP Enable” icon in
The transport bar.

Once we like what we HEAR, we will “split” the “loop” by Right Clicking, Hovering over the “EDIT” category and then choosing “Split Loop” from the sub category of the menu.

Next, we’ll select the area that we just “split”

Now COPY / DRAG this “loop” to a new track… NOTE: whenever you drag a piece of audio –
(or MIDI for that matter) to a “blank” area, Cubase will “Auto-Create” a NEW track for you.

Now, we want to turn what we have identified as our “loop” into a NEW piece of audio.

You will now see this dialog box…


Next, focusing on our new piece of audio or “loop”, we want to figure out what the ACTUAL tempo of this loop is… First, double click on it to open the “SAMPLE EDIT” window.
The Sample Edit Window…

Since we KNOW this “loop” is 4 BARS long, we need to tell Cubase, right here…


After telling Cubase the correct BAR count, it calculates the TEMPO as seen above.
Cubase now tells us that the ACTUAL TEMPO of this 4 bar loop is 104 Beats Per Minute.
The last step before closing the sample edit window is to enable the “PREVIEW”
Button.

After closing the SAMPLE EDIT window, you will notice that the “loop” region
Looks like this…

This indicates that this “loop” or “region” will adjust itself to whatever tempo
You set in the “TEMPO TRACK”…
Let’s open up the TEMPO TRACK window and set the TEMPO…


Like this…

Now we’ll see the BARS and BEATS grid change to the NEW (correct) Tempo!

You can now change the TEMPO TRACK at will and the TEMPO of audio region we worked on will
Change accordingly – Without changing the pitch!
