Included with Pro
Loop Lab
The built-in sets get you playing. Loop Lab lets you play yourself: write melodies, program drums, sample anything, then perform it all live on the main screen.

Create · Melody loops
Step Sequencer
Tap notes onto the grid, slide to hold them, and stack chords. Pick a key and a scale (minor, phrygian or major) and every note fits. Loops run 1, 2 or 4 bars, with copy and paste and an octave shift for each bar.
- Bass
- Boomer, Wobble, Donk, FM Bass, Reese, Acid
- Leads
- Hoover, Trance, Sync Lead, Supersaw, Pluck
- Keys
- Rave Stab, Rave Piano, House Organ, Juno Pad, E-Piano
- FX
- Laser, Vox Ahh
- Samplers
- Pitch Sampler and Slicer: play any sound as an instrument
- Stack instruments as layers, each with its own sound and effects
- Tap a knob's name to record its movement over the loop
- An arpeggiator that turns held chords into patterns
- Time stretch: half, double or triplet pace, reverse, and Jungle or octave styles

Create · Drum kits
Drum Lab
Program a beat across up to 14 lanes from 196 drum sounds, or import your own. Every style preset deals a fresh beat at the right tempo, and the dice deals another.
- Simple view to sketch fast, Advanced view for accents, rolls, choke and pan
- Import a batch of your own samples at once into My Sounds
- Eight kit effects: Filter, Crush, Tape, Drive, Punch, Echo, Space and Width
- Swing and humanize, so it grooves like a person played it
- Save the kit and it plays on the main screen like any other

Sample
Cut Loops From Anything
Bring in a sound and Cut Loops does the hard part. It detects the tempo (tap it in if it guesses wrong), snaps your selection to 1, 2, 4 or 8 bars, and fits it to the beat.
Record Audio
Sing, rap or play along to a metronome.
Upload From Files
WAV, MP3 or M4A, from anywhere in Files.
Audio From Video
Pull the sound out of any video on your phone.
Saved Recordings
Reuse something you recorded earlier.
Keep the pitch while changing speed, or repitch it like a record. Cut clips can become melody loops or a drum kit.
