Exploring the Behringer MS-1 MKII: Features, Sound Quality, and Performance

Authentic 1980s Sound with a Modern Twist
The Behringer MS-1 MKII is a faithful recreation of the iconic Roland SH-101, one of the most beloved monophonic synthesizers from the 1980s. Known for its classic analog sound, the SH-101 was a go-to instrument for basslines, leads, and arpeggiations in the early days of electronic music. Behringer, renowned for producing affordable recreations of classic synthesizers, has brought the MS-1 MKII to life with updated features while preserving the essential character and sound of the original SH-101. With the MS-1 MKII, Behringer offers musicians and producers a chance to capture the essence of a vintage classic without breaking the bank.
Overview:
The Behringer MS-1 MKII is a monophonic analog synthesizer featuring a single oscillator, classic SH-101-style filter, and a built-in step sequencer and arpeggiator. It captures the distinct sound and layout of the original but introduces some modern conveniences such as USB and MIDI connectivity, an updated build quality, and additional modulation options. Its compact design and straightforward interface make it easy to use, and it’s equally suitable for beginners and seasoned synthesists looking to add vintage flair to their setup.
Sound Engine:
At the heart of the MS-1 MKII is its 100% analog signal path, which delivers the same rich, warm tones that made the SH-101 a classic. The MS-1 MKII retains the original’s single oscillator design, allowing for detailed sound shaping through pulse width modulation, frequency modulation, and a noise generator. Despite its simplicity, the MS-1 MKII’s sound engine excels at creating thick basslines, smooth leads, and aggressive squelches. The analog nature of the synth ensures that it has a fat, punchy sound that stands out in any mix, making it ideal for electronic genres like techno, house, and synthwave.
Oscillators and Waveforms:
The MS-1 MKII offers a single analog oscillator with selectable waveforms, including saw, square, and sub-oscillator settings. This oscillator can be tuned across a wide frequency range, allowing for deep bass sounds or high-pitched leads. The inclusion of the sub-oscillator is crucial, as it adds depth and thickness to the sound, making it possible to create powerful basslines and layered tones. The oscillator can also be modulated using the LFO for vibrato effects, and the pulse width modulation creates interesting, evolving tones by altering the waveform shape in real-time.
Filters and Modulation:
The MS-1 MKII features a classic 24dB low-pass resonant filter, which is a key element in shaping the sound. The filter can be modulated using the envelope generator, LFO, or key tracking, allowing for expressive sound manipulation. The resonance of the filter is capable of self-oscillation, a characteristic that adds depth and character to the sound when pushed to higher settings. Additionally, the MS-1 MKII offers a flexible LFO section with triangle, square, and random waveforms, enabling modulation of pitch, filter, and pulse width for dynamic sound creation.
Effects Processing:
While the MS-1 MKII doesn’t include built-in digital effects like reverb or delay, it shines in its raw analog sound, which pairs beautifully with external effects. Many users love running the MS-1 through outboard gear or plugins to add delay or reverb, but even without effects, the synth’s natural analog richness provides more than enough presence and warmth for most uses.
Polyphony and Voice Modes:
As a monophonic synthesizer, the MS-1 MKII focuses on a single voice at a time, making it perfect for punchy basslines, sharp leads, and arpeggios. Monophonic synths like the MS-1 excel in scenarios where clarity and focus on one note at a time are crucial, such as in electronic dance music and sound design. While it doesn’t offer polyphony, its monophonic nature is true to the original SH-101 design, delivering that same tight, responsive performance.
Keyboard and Controls:
The 32-note full-sized keyboard on the MS-1 MKII offers a classic feel with velocity sensitivity. The tactile feel of the keys is responsive, and the pitch and modulation wheels allow for expressive real-time performance. Behringer has also included the iconic modulation grip handle, just like the original SH-101, allowing for keytar-style playing. The MS-1’s control panel is laid out clearly, with dedicated knobs for every function, making it easy to tweak sounds in real-time without diving through menus.
Sequencing and Arpeggiation:
One of the standout features of the MS-1 MKII is its built-in step sequencer and arpeggiator, which give users the ability to program and play rhythmic patterns on the fly. The step sequencer allows for the creation of intricate patterns with ease, while the arpeggiator offers multiple modes for generating rhythmic note sequences. Both features are essential for live performances and studio work, as they can quickly add movement and rhythm to any track.
Build Quality and Durability:
Behringer has done an excellent job with the build quality of the MS-1 MKII. The chassis feels sturdy and durable, and the controls are solid with a satisfying tactile response. The synth’s compact, lightweight design makes it easy to transport, whether you’re taking it to the studio or on stage. Despite its affordability, the MS-1 MKII doesn’t feel cheap or flimsy—it’s designed to withstand the rigors of performance and studio use.
Connectivity and Power Base:

The Behringer MS-1 MKII offers comprehensive connectivity options, including MIDI In/Out, USB-MIDI, and CV/Gate for integration with other gear. This makes it easy to use the MS-1 MKII as part of a larger modular system or DAW setup. The synth can be powered via USB or an external power supply, making it a versatile option for mobile producers or those looking to integrate it into various setups.
