The Elektron Octatrack MKII is what happens when a sampler gets tired of following the rulebook. Eight tracks of dynamic, real-time sampling power packed into a compact, road-ready chassis — this machine has been shaking up live performance setups for over a decade, and it's not done yet. From Nine Inch Nails to Thom Yorke, artists who demand more from their gear keep arriving at the same conclusion: the Octatrack MKII.
Real-Time Sampling and Sound Manipulation
Record live audio from four balanced inputs, resample internal tracks, or pull directly from the main and cue channels — then time-stretch, pitch-shift, slice, and loop your captures into something completely unrecognizable. That's the whole idea behind the Elektron Octatrack MKII.
Live Stereo Sampling with Time-Stretch and Pitch-Shift: Capture audio in real time and immediately reshape it without missing a beat — ideal for improvisational live performance and in-depth studio composition alike.
Versatile Machine Types per Track: Each of the eight stereo audio tracks can be assigned a specific machine type, so long samples, dynamic loops, and live inputs all get handled with exactly the right behavior.
Three LFOs per Track with LFO Designer: Deep, customizable modulation per track opens up wave-weaving possibilities that most samplers simply don't offer, letting you breathe movement and unpredictability into every sound.
Crossfader Performance and Scene Control
The crossfader on the Octatrack MKII isn't just for show — it's a proper performance tool. Assign parameter scenes to each side, then choose your approach. A gentle nudge creates smooth, natural transitions between states, while a sharp flick delivers wild, head-turning moments that'll leave the crowd guessing. Either way, you're the one pulling the strings.
Contactless Performance Crossfader: The silky-smooth, contactless design allows for precise transitions between A and B parameter scenes without any mechanical wear — because nobody wants their most-used control to give out mid-set.
Two Insert FX per Audio Track: A vast palette of reverbs, filters, phasers, delays, and more can be stacked per track, giving you the kind of sound-shaping depth that used to require a full outboard rack.
Scene Assignment for Dynamic Live Transitions: Set up dramatically different parameter states on each side of the crossfader and toggle or morph between them on the fly, creating transitions that are either seamlessly smooth or gloriously unhinged — your call.
Sequencing, MIDI Control, and Live Integration
The Octatrack MKII isn't just a sampler with delusions of grandeur — it's a full-blown live performance hub. Eight dedicated MIDI tracks let you sequence and automate external synths, drum machines, and hardware, complete with LFOs, arpeggiators, and parameter locks. Pair that with the legendary Elektron sequencer and you have something that can hold an entire modular setup together while simultaneously running your samples, effects, and transitions.
Eight Dedicated MIDI Tracks: Control external gear with the same level of precision as internal audio tracks, including LFOs, arpeggiators, and automation — making the Octatrack MKII the central nervous system of any hardware setup.
Live-Friendly Elektron Sequencer: Make pattern changes, introduce variations, and sequence both internal sounds and external MIDI gear on the fly, with the kind of precision that rewards both planning and spontaneity.
Full Mixing Desk Functionality: With configurable stereo inputs, balanced main and cue outputs, and a headphone output, the Octatrack MKII can serve as a portable mixing desk for your entire live rig — one less piece of gear to carry, one more reason to love it.
The Octatrack MKII Is Built to Last
The Octatrack MKII isn't trying to be everything to everyone. It's trying to be everything to the right people — live performers, sound designers, and producers who want deep creative control without being chained to a laptop. Its backlit buttons are rated for 50 million presses, its OLED screen stays readable even in dim venues, and its compact 5 lb frame fits into a backpack without complaint. It ships with nearly 5 GB of factory content from Loopmasters, Sample Magic, Origin Sound, and Samples from Mars, so creativity starts the moment you power it on. For performers who demand more from their gear, the Octatrack MKII consistently delivers.

Quick Guide
Frequently Asked Questions
The Octatrack MKII is an 8-track dynamic performance sampler and sequencer designed for live performance, sound design, and studio production. It's particularly popular among producers and performers who want deep, real-time control over samples, loops, and external MIDI gear.
The Octatrack MKII has a steep learning curve and is generally better suited to intermediate or experienced users who are already comfortable with hardware sequencers and samplers. That said, many users report that the investment in learning pays off significantly once the workflow clicks.
The MKII features several hardware upgrades over the original, including a brighter OLED screen, improved hi-res encoders, more dedicated buttons for a streamlined workflow, and a contactless crossfader. It is also fully backward compatible with all MKI projects and data.
Yes, the Octatrack MKII includes eight dedicated MIDI tracks that can sequence and automate external synths, drum machines, and other hardware with LFOs, arpeggiators, and parameter locks, making it an effective control center for a broader hardware setup.
The crossfader allows you to assign different parameter scenes to each of its two sides (A and B), then blend or switch between them in real time during performance. Moving the fader gradually morphs between the two states smoothly, while sharp movements create dramatic, abrupt transitions.
