When you manipulate music digitally, it is essential to understand the key of a song, i.e., the set of notes and chords that make up the music's foundation. When you remix a track, you may change the music pitch of whatever audio you are remixing to get the right feel, timing, and texture for your creation. 

While many software exists to help you change the key, many users may use FL Studio as it has several pitch-shifting plugins like Pitcher, Newton, and Harmor to adjust the pitch of a sample without much affecting the sound quality. In this article, we will see how to change keys in FL Studio on desktops and phones. So, without wasting time, let's quickly get started. 

Change Pitch of Piano Roll in FL Studio on PC

You can use MIDI packs to start a song, but not like the original key. There may be cases where you may find a sample better for a different song in a different key. Here, you can change the key of a MIDI part using the Piano Roll than the Sample Settings. Let's see how to change the key in FL Studio. 

Step 1. With the Draw tool, double-click the MIDI clip you want to change the key of. Doing so will open up the Piano Roll with the MIDI notes.

Step 2. Press Ctrl+A (Windows) or CMD+A (Mac) to select all notes in the part. 

Step 3. Tap the arrowhead icon in the upper-left corner of the Piano Roll window. Hover your mouse over "Edit" to see some transposing options in the second section.

Step 4. The "Transpose Up" and "Transpose Down" tabs are both in increments of a semitone.

Now, if you have a MIDI part in the C# minor key, you can increase the key of the MIDI part significantly by 200 cents to be in F# major.

Change Pitch of a Sample in FL Studio Mobile

FL Studio makes the job pretty easy if you have an audio clip or sample that you would like to change the key.

🎊Here's how to change the key in FL Studio in a few steps.

Step 1. Have the audio clip selected (say as a pattern).

Step 2. After selecting the audio clip, double-click it to bring the "Master" window for your audio file. 

Step 3. Go to the "Pitch" option under the "Time Stretching" option in the Master window to change the key.

Step 4. You can select a different mode through the "Resample" dropdown menu at the right section of the window.

Step 5. You can easily change the pitch if you choose "Auto" as the Mode. 

Step 6. If you look at the top left-hand side of the screen, you will see it says "Pitch shift - 100 cents". On changing the knob, it will change the amount of cents that the pitch is being changed. 

Note: Every 100 cents is a half step or a semitone. So if you go -100 cents, it will lower one key. That means if it were in the key of G, it would lower to the key of F sharp. 

Step 7. Click the white cross button (x) at the upper left window area to close the Master window. Then, listen to the audio to see the changed results. 

By repeating the same steps, you can change the key by making it half a cent higher.
