zenAud.io Details

zenAud.io ALK2 is the world's first sequenceable live looper/DAW. It allows an arbitrary of number of tracks and MIDI or audio clips to be looped in a live performance. Its design breaks the traditional loop pedal operation (in which the musician simultaneously performs the loops and controls the looper's operation) across two distinct phases: planning and performance.

In the first phase, you plan your song using a refinement of the pencil tools available in all standard DAWs. Using so-called "record" and "play" pencils, you can create a musical arrangement designed to be performed live. Record loops, drawn with the record pencil and which have a red outline, are placeholders for material the musician will perform onstage. Play loops, which have a green outline, in turn refer to specific record loops, completing the traditional looping operation.

Once you've created an arrangement, you hit "Record" on stage which triggers the zenAud.io's performance mode. In this mode, ALK2 takes over both monitoring and the record/play operation of the loopers on each of the tracks in the arrangement. As a result, you are free to focus exclusively on your performance, allowing you to realize rich arrangements with the rhythmic tightness and sonic polish reminiscent of electronic music styles.

zenAud.io ALK2 and ALK2 Solo are available for purchase by direct download from the zenAud.io online store at the price of €149 for ALK2 and €39 for ALK2 Solo, which includes one year of free updates.

zenAud.io ALK runs on Windows 8.1 (64-bit) or higher and macOS 10.10 Yosemite or higher.

zenAud.io's Features

ALK2 has a host of innovative features that give you amazing, granular control of your sound - without distracting you with minutia.

Unique arranged live-looping workflow. ALK allows quick and easy arrangement of where you want to perform live, using Record Loops, and where you want it to play back, using Play Loops. Build up your song structures in minutes!

ALK’s loop sequence view lets you take in your entire arrangement at a glance. Break away from endlessly layered loops and create structures: verses, choruses, b-sections and soloes.

MIDI looping is supported out of the box, giving you the ability to create loops using your entire array of software synths and beat machines. Adjust the tightness of your groove on the fly using ALK’s elastic quantize feature, simply by turning a dial.

Symmetric Routing is ALK’s answer to traditional mixer channels and effects sends/returns. Any track (audio or MIDI) can act as a mixer or group, and an effect send simply becomes a regular output!

ALK supports VST/AudioUnit effects and instruments allowing you to live loop with all your signature sounds. Plugins can be automated from the arrangement, or controlled with your favorite MIDI controller.

ALK’s Magnetic Note Repeat automatically smooths out notes triggered off-grid, easing them gradually into lockstep. Perfect for laying out a four-on-the-floor kick drum or eighth-note hi-hat pattern on the fly.

Draw accurate automation using intuitive trackpad gestures. Using a combination of mouse position, horizontal and vertical swipe gestures, and rotation gestures, you can control the shape of your curve. Adding control points for more precision is as easy as clicking within the region.

ALK's approach to performed automation, like filter or reverb sweeps, is to treat the knob, pad, or pedal as an instrument in its own right: on its own track. Routings are dynamic and can be changed over a song or set, so a single knob could control a filter sweep in one song, and a reverb sweep in the next.

With ALK's panic features, you don't need to worry about making the occasional mistake. Through a click of a pedal, you can have a perfectly played reference version of the loop replace it - useful for when you absolutely need the song to progress.

With hover auditioning, changing sounds is as easy as hovering the mouse over the track in question. However, it's still possible to leave monitoring on or off by switching to manual auditioning in the track's context menu.

ALK2 Reviews

"ALK2's track-based workflow appears to transcend the limitations of hardware-based live looping by enabling and facilitating the creation, programming and presentation of complex, pedal-free, multitrack live looping performances in a DAW-style environment."

"zenAud.io ALK2 is an outstandingly simple to use looper station, that does not share the typical shortcomings of similar products, complements their functionality with the advantages of a sequencer and also provides innovative automation options."

"ALK2 gives a wonderful glimpse into the future of live sequencing and recording."

“Over the time of our test, we became aware that the purpose of ALK2 goes far beyond that of just a better looper.”

“Costing only €39 for the Solo version and €149 for the Full version, the ALK2 is not only cheaper than your regular looping pedal, it’s just better and a great songwriting tool.”

"Relating ALK2 to a looper pedal brings to mind the old 'DJing with Ableton Live vs turntables' comparison, in terms of the simplification of the performance process and the immense creative empowerment that software brings over hardware."

"Occupying the middle ground between the focus of looping hardware and the flexibility of DAW software, ALK2 could be just what you’re looking for."

"Working with ALK2 is a lot of fun and has what it takes to inspire one's own creativity and spontaneously implement ideas"

"For hands-free, pedal-free and worry-free live looping zenAud.io ALK2 is the best possible choice"

"As a looping musician, I can’t believe the stages I used to go through just to create one track without ALK. With it I am now more confident than ever on stage."
