To transpose a MIDI or audio region in Logic Pro, select it, press **I** to open the Inspector, expand **Region**, then change **Transpose** by the required number of semitones. Positive values raise the pitch, and negative values lower it. For selected regions or notes, the U.S. default shortcuts are **Option-Up/Down Arrow** for one semitone and **Option-Shift-Up/Down Arrow** for an octave.

For a whole song, inspect the region types first. Changing the project key doesn’t automatically move every recording and MIDI part together. I’d make one phrase work, then extend the change across the arrangement after checking loops, Session Players and drums.

This is the Mac workflow. Keep an untouched copy before a broad edit, especially when the project already has pitch offsets or several ways of following harmony.

## Choose the pitch change you actually need

| What should change?                          | Use                                 | What it changes                                   |
| -------------------------------------------- | ----------------------------------- | ------------------------------------------------- |
| A whole MIDI phrase during playback          | Region Inspector: Transpose         | A playback offset; the stored notes stay editable |
| Only selected MIDI notes                     | Piano Roll pitch edit               | The selected note pitches                         |
| A recorded or imported audio clip            | Audio Region Inspector: Transpose   | The selected region’s pitch                       |
| What a MIDI instrument receives in real time | Transposer MIDI FX                  | Incoming MIDI before the instrument responds      |
| Parts that follow the song’s key or chords   | The appropriate key or chord source | Only the regions configured to follow that source |

Apple’s [default key-command table](https://support.apple.com/guide/logicpro/main-window-tracks-and-various-editors-lgcpe8314fe2/mac) confirms the semitone and octave shortcuts. Those keys also serve other functions in other selections, including automation and Marquee operations. Click the intended editor and check the selected objects before using them. A custom key-command preset can differ.

![Three pitch changes: note editing changes stored MIDI notes, Region Transpose changes playback pitch, and Project key requires checking Pitch Source](https://storage.ghost.io/c/20/71/2071c898-de7d-454c-9b19-3de1581e628d/content/images/2026/10/logic-pro-transpose-choices.webp)

Choose what should change before choosing the control: notes, region playback or the source followed by a region.

## Transpose a MIDI region without rewriting its notes

1. Select the MIDI region in the Tracks area.
2. Press **I** and expand the Region parameters.
3. Double-click **Transpose** and enter the offset. Use **\-2** for two semitones down or **12** for an octave up.
4. Play the phrase with its actual instrument. Check the bass register, chord voicing and any non-musical trigger notes.
5. To undo the offset, restore the previous Transpose value. Use 0 only if that was its original value.

Apple’s [MIDI region parameters](https://support.apple.com/en-us/guide/logicpro/lgcpf7c0d270/mac) describe Transpose as a semitone change during playback. If the Piano Roll still shows the original note positions, that doesn’t mean the offset failed. A playback parameter and a note edit are different things.

For example, C, E and G shifted down two semitones become B-flat, D and F. The major-triad shape stays intact. Transposing the root does not automatically turn a major chord into a minor chord.

If you later need the offset written into the MIDI data, the same manual documents **Functions > MIDI Region Parameters > Apply All Parameters Permanently**. Preserve a copy and review the other region parameters first, because this command applies more than transposition and then resets the affected playback parameters. Do not use it merely to make the screen match what you hear.

### Change only the selected notes

Open the region in the Piano Roll and select the notes that should move. Drag them vertically, or use the default semitone or octave shortcuts with the editor focused. Apple’s [note-pitch instructions](https://support.apple.com/guide/logicpro/change-the-pitch-of-notes-lgcpfa6e848c/mac) describe the vertical move and the pitch feedback in the help tag.

Check the selection before pressing Command-A, since the editor can show more than one region. For moving a chord’s upper voice while its bass stays put, select that voice alone. The [Piano Roll workflow](https://logicpros.net/logic-pro-piano-roll/) covers selection and voicing in more detail.

## Transpose audio while keeping the project tempo

For a vocal, guitar, sample or imported backing track, start with the region method in [Apple’s audio-pitch instructions](https://support.apple.com/en-us/102146). You do not need to change the project’s BPM to ask for a different pitch.

1. Select the audio region in the Tracks area.
2. Press **I**, then expand **Region**. Option-R opens the Region Inspector separately.
3. Set **Transpose** for the semitone change. Drag in the field, or double-click it and type the value. The [audio region reference](https://support.apple.com/en-us/guide/logicpro/lgcpf7c0af60/mac) notes that the pop-up menu’s values step in whole octaves.
4. Use **Fine Tune** for a smaller offset in cents when the recording sits between semitones.
5. Listen to consonants, sustained notes, attacks and the transition into the next region. Recheck timing against the unchanged project tempo.

Whole-region transposition moves the recording as a whole. It doesn’t selectively repair an off-key syllable while leaving every other note untouched. Use [Flex Pitch for individual vocal-note correction](https://logicpros.net/logic-pro-flex-pitch/) when that’s the actual job.

Pitch processing can change the character of a recording, especially with a larger shift. Judge the result as a musical choice. Compare it in the mix, and consider a new performance when the voice or instrument no longer suits the part. There’s no universal artifact-free semitone limit.

## Why changing the project key leaves some parts behind

**Pitch Source decides which regions follow a key or chord change.** Apple’s [current Pitch Source guide](https://support.apple.com/en-us/guide/logicpro/lgcp047d0131/mac) makes several distinctions that matter in a mixed arrangement:

- Ordinary audio regions do not change pitch with the key signature.
- MIDI regions default to Off, but can follow key signature changes.
- Pitched Apple Loops can follow the key signature; non-pitched material has different defaults.
- Session Player regions can follow the Chord track or their own region chords.
- Some older projects also offer Project Key, which follows the initial project key rather than later key-signature changes.

To change the project key at its start, place the playhead there, choose **Beats & Project** from the LCD display menu, then choose the key field. Apple documents that route in [setting the project key signature](https://support.apple.com/en-us/guide/logicpro/lgcp42b42603/mac). It changes the source those followers use. It doesn’t tell Logic to transpose every audio file.

If an older video tells you to open the **Transposition track**, check the project’s age. Apple says Pitch Source replaces that track, while projects created in older Logic versions can retain it. You’re not necessarily missing a current global-track checkbox.

For loop-specific choices, including key and region-chord behavior, use the [Apple Loops guide](https://logicpros.net/how-to-use-apple-loops-in-logic-pro/). A loop that already follows a changed key should not receive the same shift again just because the other audio needed a manual offset.

A short sample or riff that should keep following key changes can become your own Apple Loop. Trim the region so it starts and ends exactly on a beat, choose **File > Export > Region/Cell to Loop Library**, select the Loop type and set its key. Apple’s [steps for creating your own Apple Loops](https://support.apple.com/guide/logicpro/create-your-own-apple-loops-lgcp1de12b57/mac) say Loop files conform to project tempo, scale and key, while One-shot files ignore all three. Then replace the original region with the new loop from the Loop Browser. To send any loop back to the key it was recorded in, set its Pitch Source to Off.

## Move a whole song to another key

Imagine lowering a C-major arrangement to B-flat for a singer: the intended change is two semitones down. The following is an editing plan. It doesn’t mean every region type shares one transpose switch.

1. **Preserve the arrangement.** Save a separate project copy before broad changes. Note existing region offsets and any older global transposition data.
2. **Separate pitched parts from triggers and drums.** Leave drum mappings, articulation keyswitches and other control notes alone unless you intend to change those assignments.
3. **Move ordinary pitched MIDI and audio that do not follow a changed harmonic source.** Apply the intended interval relative to each region’s current offset. A region already at +3 should end at +1 for a two-semitone downward move, not at -2.
4. **Update the followers through their actual source.** Change the key signature for regions following it. For a Session Player following the Chord track, transpose the relevant chords; for one following region chords, change those chords. Exclude those already-shifted parts from an additional manual offset.
5. **Review the full arrangement.** Check intro, verse, chorus, transitions, alternate takes and any later key changes. Compare melody, bass, chords and loops together, then check the singer’s range.

For selected chords, Apple documents [Transpose Chords +1 Semitone and -1 Semitone](https://support.apple.com/guide/logicpro/transpose-chords-lgcp10b4d637/mac) in the chord shortcut menu. That edits chord information, which isn’t the same operation as dragging MIDI notes. The [chord progression guide](https://logicpros.net/logic-pro-chord-progressions/) explains how the global Chord track and region chords relate to Session Players.

Keep the project tempo unchanged during this pass. [Varispeed](https://support.apple.com/guide/logicpro/varispeed-alter-speed-pitch-audio-lgcp1cc678a7/mac) serves a different purpose: Speed Only changes speed while compensating pitch, and Varispeed (Speed and Pitch) changes both together. It’s useful for a tempo-and-pitch experiment, but it isn’t the region-by-region key change described here.

## Use Transposer when the change belongs to live MIDI

The [Transposer MIDI plug-in](https://support.apple.com/guide/logicpro/transposer-controls-lgceee5a5e6f/mac) shifts incoming notes by up to 24 semitones in either direction and can constrain them to a scale. Put it in a [software instrument channel strip’s MIDI FX section](https://support.apple.com/guide/logicpro/use-midi-plug-ins-lgcef1c11e8f/mac) when you want that processing before the instrument.

It doesn’t process an audio recording. Also check its Root and Scale settings: moving a phrase by a fixed interval and forcing it into selected scale notes are different operations. If a phrase’s intervals change unexpectedly, inspect the scale constraint as well as the transpose amount.

## When the result is wrong, inspect the extra pitch layer

**MIDI does not move:** check **No Transpose** in the Track Inspector. Apple’s MIDI region reference says it makes the channel strip ignore region Transpose parameters. That can protect drums, so do not disable it across the project merely to fix one pitched part.

**Only loops or players move:** compare Pitch Source across the relevant regions. Ordinary audio needs its own pitch edit. A key-signature follower needs the intended key source.

**The shift is twice what you expected:** inspect region Transpose, note edits, MIDI FX, instrument tuning and key or chord following. Changing the same phrase in two places can compound the shift. Restore the last deliberate change before adding another correction.

**The wrong drum or articulation plays:** undo the note transposition and separate musical pitches from keyswitches or mapped drum notes. Changing a trigger note can select a different sound rather than a higher version of the same sound.

After the part is in the right key, continue with the [Record & Edit hub](https://logicpros.net/logic-pro-recording-editing/) for timing, comping and the rest of the edit.
