Load any audio file into Quick Sampler, or create samples by recording directly into Quick Sampler with hardware like a microphone, synth, or drum machine. Automatically tune and loop a sample, create a "sliced" instrument that's great for a drum loop or vocal phrase, or use Quick Sampler as a simple one-shot player for single drum hits. You can also convert sliced loops into a Drum Machine Designer kit, where individual slices are loaded onto pads to provide maximum control of playback and plug-in effects.
Add a sample
- In a project, choose Track > New Software Instrument Track.
- Click the Instrument slot in the new channel strip, then choose Quick Sampler from the pop-up menu.
- To open the Quick Sampler window, click Quick Sampler in the Instrument slot.
- Drag a file from the Logic Pro files browser, Loops browser, a region from any track or from the Finder into one of these areas of the Quick Sampler waveform display:
- If you want Quick Sampler to automatically set the tuning, loudness, length, and loop points of the sample, choose Optimized.
- If you want to keep the original tuning, loudness, and length of the sample, choose Original.
- To listen to your sample, play the Quick Sampler with musical typing or a connected USB or MIDI keyboard. The sample is mapped to keys above and below the defined root key, which by default is C3. Notes below the root key play the sample at a lower pitch and slower speed, while notes above play the sample at a higher pitch and faster speed a sample.
Choose the sample playback mode
After you’ve added the sample to Quick Sampler, you can choose the playback mode. Click one of these options above the waveform display:
- To play a sound across the keyboard range or if you want to loop a sample, choose Classic mode. The sample plays while you hold a key and stops when you release.
- To play a sample from start to end whether a key is held or not, use One Shot mode. A simple note trigger will play the entire sample. Use this for triggering single drum sounds.
- To divide a sample into individual hits, use Slice mode. Slice mode analyzes the sample and divides it into slices based on the transients in the sample. The slices are then mapped to keyboard keys so you can play each slice independently. You can also create a Drum Machine Designer track from a sliced sample, where individual slices are loaded onto pads to provide maximum control of playback and plug-in effects.
Use Flex mode
Click the Flex button to turn on Flex mode. When Flex mode is on, your sample plays at the original length and speed of the source file—even if you play above or below the root note of the sample. Use Flex mode and Follow Tempo with a melodic phrase or drum loop to transpose the pitch in real time while matching the current project tempo.
After enabling Flex mode and Follow Tempo, individual slices stretch or contract depending on the original tempo of the loop and the current project tempo. Sampler stretches slices so that there are no gaps between slices. This is especially useful when you want to take a fast loop and play it at a much slower tempo.
Edit the sample
You can use the Quick Sampler waveform display to set sample start and end points, set loop points, set fade in and fade out points, and more.
Create a Drum Machine Designer track from a sliced sample
You can quickly add a Drum Machine Designer track to your project based on a sliced sample.
- Add a sample to Quick Sampler, then click Slice.
- Make adjustments to the slices in the Sampler waveform display.
- Click the Action pop-up menu (or Control-click the Sampler waveform display), then choose Create a Drum Machine Designer Track.
Logic Pro automatically creates a new software instrument track with Drum Machine Designer inserted. Each sample slice is mapped to a pad in the Drum Machine Designer. Each pad corresponds to a particular MIDI note.
A new MIDI region is also created and placed at the beginning of the project in the tracks area. The region contains MIDI notes of each slice placed sequentially in ascending order, so when you play the project back, it plays the sample back as it sounded in Quick Sampler. But you can quantize the notes, add or remove notes, and make any other edits as you would to any MIDI region in the Piano Roll Editor.
You can also quickly create a Drum Machine Designer track, as well as other sample-based software instrument tracks, by dragging audio files to the track header in the main window.
Edit samples in the Drum Machine Designer
You can edit each sample slice directly within the Drum Machine Designer. Click a pad in the drum grid to see the sample in the waveform display, below the drum grid. Change the playback mode, adjust the start and end point of the sample, adjust the fade in and fade out, and more.
Additionally, you can access of all of the Quick Sampler controls, which in the Drum Machine Designer are separated into two page views:
- Click Q-Sampler Main to see and edit the sample in the Quick Sampler waveform display.
- Click Q-Sampler Detail to change the sound of your sample with the Quick Sampler’s two LFO (low-frequency oscillators), Pitch envelope, Filter envelope, and Amplitude envelope.
Create a MIDI region from a sliced sample
You can create a MIDI region of a sliced sample, then add it to the Tracks area or a Live Loops cell. Drag from the lower portion of the waveform display in Sampler to the Sampler track lane in the Tracks area or to a cell of the Sampler track in the Live Loops grid.
You can also copy and paste the MIDI region:
- Click the Action pop-up menu , then choose Copy MIDI Pattern.
- You can paste the MIDI region into the Tracks area or a Live Loops cell:
- In the Tracks area, select the Sampler track, move the playhead where you want to place the MIDI region, then press Control-V.
- In the Live Loops grid, select an empty cell of the Sampler track, then press Control-V.
The pasted region contains MIDI notes of each slice placed sequentially in ascending order, so when you play the project back, it plays the sample back as it sounded in Quick Sampler. But you can quantize the notes, add or remove notes, and make any other edits as you would to any MIDI region in the Piano Roll Editor.
