How to change the pitch and tempo of a song

Pitch and tempo are separate controls in Morpha, so you can move a song into a more comfortable key without slowing it down, or stretch time without detuning it. Here is how to do both.

Step by step

1. 1
   Open your file

   Go to the studio and drop in your track. Any common format works, including MP3, WAV and FLAC.

2. 2
   Open advanced settings

   Below the presets, open the advanced settings so you can see the individual pitch and tempo controls.

3. 3
   Set the pitch

   Enter a positive number of semitones to raise the key, or a negative number to lower it. Twelve semitones is one full octave.

4. 4
   Set the tempo

   Adjust the tempo or speed factor to make the track faster or slower. Leave it at its original value if you only want a key change.

5. 5
   Transform and compare

   Run the transform, then use the player to compare the result with the original. Nudge the values and rerun until it sits right.

6. 6
   Download

   Export the result as an MP3 or WAV. The file is saved straight to your device.

Tips

• Small pitch moves of one or two semitones sound the most natural.
• For a vintage varispeed feel where pitch and speed move together, use the tape-style combined mode instead of separate controls.
• If the rhythm feels off, reset tempo to its original value and change only the pitch.
