Taking a classic synth into the modern world
MS-20 style circuitry stays true to the original sound, with the Behringer K-2 bringing this classic synth into the modern era. The original synth was renowned for changing the synthesizer world. The award-winning semi-modular monophonic synth providing advanced way to create sounds and timbres at the time. Since then, it has held its notoriety throughout the years thanks to its analog circuitry and versatile parameters that make it so sought after.
The K-2 stays faithful to the original, retaining the same circuitry, versatile VCFs and powerful oscillators whilst introducing modern-day connectivity. With 36 controls in total, the Behringer K-2 provides a hands-on approach to sound design and tone-sculpting. It provides you with the means to create limitless sounds and even expand your sound design capabilities with external gear.
Pure analog circuitry
At the heart of the Behringer K-2 is a pure analog signal path. Great care has been taken to stay true to the original, keeping the same VCO VCF and VCA design with matched transistors and JFETs. This faithful recreation provides exceptional sound shaping options, allowing you to create everything from powerful basses to leads, pads and everything in between. You can then add texture by introducing the wide range of amazing effects, ranging from delays and reverbs to distortion.
Vintage oscillators and versatile VCFs
The Voltage Controlled Oscillators deliver a wide variety of sounds from the four variable oscillator shapes. Each of the shapes has variable pulse widths and ring modulation for in-depth tone sculpting. The dual oscillators come complete with a VCO mixer, allowing you to control the volumes of VCO 1 and VCO 2 and even blend between the two for interesting sonic results.
The main core of the K-2 is spearheaded by the K-2s versatile 24 dB/octave filter, allowing you to switch between High and Low-Pass Cutoff frequencies, as well as their respective resonance settings. The high-pass filter allows you to set the levels of the signals below the cutoff frequency. This results in the reduction of fundamental and lower-order harmonic levels. The low-pass filter controls the volume of the signals above the cutoff, reducing high-end harmonic content. This can add texture and skew the way tones sound for in-depth control.
Pushing the envelope
Accompanying the VCOs and VCFs are the dual envelope generators. The envelope generators provide further tone-sculpting capabilities by modulating your sound in various ways. The first generator affects the frequency modulation, providing controls for Delay, Attack and Release. The second envelope adjusts the cutoff frequency and amplitude modulation of the VCA. Controls for the second generator include Hold, Decay, Attack, Sustain and Release.
16-note poly-chain, Eurorack ready design
Although the K-2 is a monophonic instrument, the built-in 16-note Poly Chain functionality allows you to combined multiple synths for up to 16-voice polyphony. This can be highly useful for live performances and experimenting with different sounds and gear.
The rugged yet compact design makes the synthesizer highly portable. It can easily blend in with the studio or on the road. One of the most versatile design aspects is the ability to transfer the K-2 into a standard Eurorack case. It also features MIDI and USB connectivity on the rear for use with computers and music production.
