Analog Synthesizer Behringer MS-1 MK II-RD — 32-voice polyphony, 37 keys

The Behringer MS-1 MK II-RD is an analog synthesizer with 32-voice polyphony and a 37-key keyboard that blends classic analog sound with modern playability. Designed for hands-on sound design, the instrument provides direct access to oscillators, filters, envelopes and modulation sources. Its architecture supports layered and polyphonic patches while preserving the character of vintage analog timbres, and the compact 37-key format suits both studio desks and stage rigs.

Advantages

The MS-1 MK II-RD delivers true analog signal paths for warm, harmonically rich tones and a polyphonic engine that enables complex chords and textures. Physical front-panel controls offer immediate editing without deep menu diving, and the 37-key layout balances playability with portability. Connectivity options allow straightforward integration with MIDI controllers and external gear, while built-in performance controls facilitate real-time modulation and expressive playing.

Suitable for

• Live performance setups requiring polyphonic analog sounds
• Studio production and sound design for electronic, pop and experimental music
• Education and practice where hands-on synthesis learning is needed
• Integration with MIDI controllers and DAW-based workflows

Key specifications

• Analog signal path with dedicated oscillators and filters
• 32-voice polyphony for layered and chordal playing
• 37 full-size keys with velocity sensitivity
• Extensive front-panel controls for oscillators, filter cutoff/resonance, envelopes and LFOs
• Multiple modulation sources and routings for realtime sound shaping
• Performance controls including pitch/mod wheels and assignable knobs
• Compact footprint suitable for desktop or stage use
• Standard MIDI connectivity for external sequencing and control

How to use

Power the instrument, connect audio outputs to a mixer or audio interface, and set a MIDI source if desired. Select or initialize a patch, then shape the sound using the front-panel oscillators, filter and envelope controls. Use the modulation section and performance wheels to add movement and expression. For polyphonic textures, play chords across the 37-key keyboard; for single-voice leads or sequences, reduce polyphony or adjust oscillator settings. Save or recall patches according to the device’s workflow when applicable.

Usage recommendations

Position the synthesizer on a stable surface at a comfortable playing height, and use good-quality audio cables for signal integrity. When integrating with a DAW, set appropriate MIDI channels and buffer settings to minimize latency. For sound design, begin with simple oscillator and filter settings, then gradually introduce modulation and envelope changes to explore the instrument’s analog character.
