For sample and loop based musicians, Logic Pro and Logic Express have a quick solution to getting a track started and keeping the creative flow going with this clever Tempo feature.

Note: In order for this feature to work properly you must apply a little musical knowledge beforehand:

Ensure you know the exact length of your sample loop in beats and bars.

For the best results make sure you know the meter (time signature) of the loop and apply it in the transport bar

---

Step 1

In the Arrange page click on the audio loop you wish to use as your tempo base in order to select it. The loop in this example is 1 bar in length and is in the 4/4 time signature.

---

Step 2

Click in the Bar Ruler and drag the resulting green stripe to match the length in beats and bars of the sample. As the sample in this example is 1 bar in length, the green stripe is lengthened to 1 bar.

Note: If the sample had been 1.5 or 2 bars in length, the green stripe would have reflected this also.

---

Step 3

In the menu bar at the top of the screen select Options>Tempo>Adjust Tempo using Region Length and Locators.

---

Step 4

From the resulting pop-up dialogue box click the Globally button in order to change the tempo of the whole song to match your sample.


Note: If you click on Create in the dialogue box a tempo change will be created from the point of the green stripe in the Bar Ruler

---

Step 5

You have now performed a tempo change in Logic to match the tempo of your chosen sample. You should now see:

• The green stripe in the Bar Ruler matches the length of your sample
• The tempo in the Transport bar has changed

Enjoy!
