Behringer has announced its Korg MS-20-esque synth, the K-2 MK II.
Although only produced from 1978 to 1983, Korg synthesizers have been favored by numerous world-famous artists including: Aphex Twin; Arcade Fire; Daft Punk; Depeche Mode Gorillaz; Snarky Puppy and a host of others. An ultra-affordable and modern homage to that iconic synthesizer, the K-2 MK II lets you conjure up virtually any sound with incredible finesse and ease. It features a pure analog signal path, dual authentic VCOs, extremely flexible VCF and VCA filters and now also featuring OSC sync, FM and PWM plus V/Oct. for all CV/Gate in/outs.
Great care has been taken in engineering the K-2 MK II, including the true to the original VCO, VCF and VCA designs and pure analog circuitry with matched transistors and JFETs. This highly-focused attention to detail is what gives K-2 MK II its ultra-flexible sound shaping capability, which covers everything from super-fat bass and lead tones to stunning effects – all the way out to the otherworldly sounds of your imagination.
The very heart of K-2 MK II’s sound is its versatile 6 dB High/12 dB Low filter. The high-pass filter sets the level of signals below the cutoff frequency, effectively reducing the fundamental and lower-order harmonics levels. The low-pass filter controls the level of signals above the cutoff, which reduces higher-order harmonic content. K-2 MK II’s VCF Peak controls provide emphasis to the signals at the crossover frequency.
K-2 MK II’s authentic Voltage Controlled Oscillators (VCOs) provides an incredible range of 4 variable oscillator shapes with variable pulse widths and ring modulation for the ultimate in sound creation. VCO 1 waveform choices include triangle, reverse-sawtooth, noise and pulse. VCO 2’s waveform can be selected from reverse-sawtooth, square, narrow pulse and ring, where both oscillators are operating. The VCO Mixer allows you to adjust the levels of VCO 1 and VCO 2 to create an overall mix and a wide range of amazing effects.
K-2 MK II’s Low Frequency Oscillator (LFO), the Modulation Generator, features a selectable Waveform (reverse sawtooth, triangle, sawtooth) and 2 separate Envelope generators to help you craft incredible sounds! Envelope Generator 1 has controls for Delay, Attack and Release Time, while generator 2 adjusts the cutoff frequency modulation, as well as amplitude modulation of the Voltage Control Amplifier (VCA). Dials for this generator include Hold, Decay, Attack, Sustain, and Release for unparalleled envelope-shaping control.
While it is a monophonic instrument (one note at a time), K-2 MK II’s 16-note Poly Chain function lets you combine multiple synthesizers for up to 16-voice polyphony – plus provides vastly improved reliability and stability over its 1970s and ’80s predecessors.
Designed to handle the rigors of life on the road or in the studio, your K-2 MK II can easily be transferred into a standard Eurorack case for the perfect integration into your existing system.
K-2 MK II has 36 controls, all laid out in a highly intuitive format that puts the joy back into your music creation. And you can expand K-2 MK II’s tone-sculpting capabilities beyond your wildest dreams by utilizing the multi-I/O patch bay to connect external devices at virtually any point in the signal path.
