The Behringer K-2 MKII is an analog, semi-modular desktop synthesizer (80HP Eurorack-compatible) replicating the circuit design of the legendary 1978 Korg MS-20. It features dual VCOs, the gritty dual high-pass/low-pass MS-20 filters, a flexible patch bay, and expanded modern synthesis routing.

Core Specifications and Details

• Architecture: Analog monophonic semi-modular synth with 2 VCOs, ring modulator, and external signal processor (ESP).
• Filter Options: Includes both historical versions of the MS-20 filter circuits (early high-pass/low-pass revisions).
• Connectivity: USB/MIDI implementation, 5-pin MIDI In/Thru, 1/4" audio output, and a multi-I/O 3.5mm patch bay.
• Poly Chain: Features a 16-note Poly Chain function to link multiple units for multi-voice setups.

Key Advantages Over Competitors (e.g., Korg MS-20 Mini)

• Standard 1V/Octave CV Support: Unlike the original MS-20 and Korg MS-20 Mini which used the obsolete Hz/V standard, the MK II natively tracks 1V/Octave, eliminating the need for external conversion gear when patching with modern Eurorack modular setups. [1, 2]
• Added Synthesis Tools: Adds a Pulse Width Modulation (PWM) input, Oscillator Sync (syncing VCO 2 to VCO 1), FM to Oscillator 2, and a reverse trigger input directly into the patch layout—features derived from the rare MS-20M variant that are absent on standard MS-20 desktop/mini releases. [1, 2]
• Form Factor & Build: Built into a robust metal desktop chassis that easily unbolts to fit standard 80HP Eurorack cases, avoiding the wobbly knobs and flimsier keybed housing reported on the MS-20 Mini. [1, 2]
• Price Value: Offers aggressive vintage analog tone-sculpting at a significantly lower cost than original vintage units or official Korg reissues
