BEHRINGER / AKS MINI

The legendary, Pink Floyd-favored “EMS Synthi AKS” is reborn as a polyphonic synth! This 3-VCO pure analog design faithfully reproduces 1970s circuitry. Equipped with a traditional dual-axis joystick, spring reverb, and a knob-recording 16-step motion sequencer, it infuses modern production and live sets with the ultimate vintage sound.

The “AKS MINI” is a new-generation programmable analog synthesizer that faithfully reproduces the circuitry of the legendary attaché case-style “EMS Synthi AKS”—a name etched into synthesizer history—in an astonishingly compact size, while evolving it into a 3-voice polyphonic instrument.

Five Core Advantages That Inspire Modern Creativity
1. “Pure Analog Signal Path” Faithfully Reproducing the Circuitry of a Historic Masterpiece
From the three VCOs (voltage-controlled oscillators) at the heart of the sound, through the legendary AKS filter (VCF), all the way to the VCA, it maintains a pure analog signal path from start to finish with absolutely no compromises.
The rich waveforms produced by the adjustable sawtooth and square waves generate the rumbling bass and sharp leads essential to classic psychedelic rock and experimental electronica.

2. Overwhelming physical control via the traditional “2-axis joystick”
The “2-axis joystick”—an iconic feature of the original hardware—is faithfully reproduced on the front panel.
You can freely assign any two parameters (e.g., filter cutoff and LFO speed) to the X and Y axes for intuitive, hands-on control. This enables organic and intricate modulation expressions that are fully integrated with your performance—something absolutely impossible with mouse clicks or standard knob operations.

3. 128-Step Motion Sequencer That Dynamically Records Knob Movements
In addition to recording notes, it features a “Motion Sequencer” that captures the movements of the front-panel knobs exactly as they occur.
With a maximum of 16 steps and 10 pattern memories, you can easily build “patches that evolve on their own”—where the sound continues to change gradually or dramatically over time. It also features a “Smooth” function for seamless transitions and an instant data clear function.

4. “27-Key Touch Keyboard” and Comprehensive Play Modes for Enhanced Playability
It features a 27-key capacitive touch keyboard that delivers high playability without compromising the unit’s compact size.
In addition to “Poly (Polyphonic) Mode,” which weaves together chord progressions and beautiful layered harmonies, it features “Unison Mode,” which stacks three VCOs to produce a thick, wall-like monophonic sound. Furthermore, the high-quality digital spring reverb, which adds a rich sense of space and depth, achieves both a space-saving design and inspiring effects.

5. State-of-the-art connectivity and full MIDI specifications that integrate seamlessly into any production environment
While embodying the spirit of vintage gear, the interface is fully modern.
In addition to a 5-pin DIN MIDI IN jack, it features a USB-C (MIDI) port. Since all parameters support NRPN/CC control, you can freely perform precise automation from your DAW and bulk load/save patch data. Furthermore, Sync input and output jacks enable perfect tempo synchronization with other drum machines and modular synths during live performances.

True portability for any setting
With dimensions of 40 x 124 x 193 mm and a weight of just 0.36 kg, it features an ultra-lightweight and compact design.
Since it supports power delivery via USB Type-C, it can be powered not only by a studio PC but also by a smartphone charger or a portable power bank. Whether at your usual production desk, on a live stage, or by your bedside while traveling, wherever inspiration strikes, that space instantly transforms into a rich analog sound laboratory.
