The Stylophone S2 is a unique and powerful analogue synthesizer that bridges the gap between the classic pocket instrument and professional-grade music equipment. Originally released by Dubreq, the S2 was designed to provide a much deeper sonic palette than its predecessors while maintaining the iconic stylus-based interface. Whether you are a seasoned synthesist or a curious beginner, understanding how to navigate this instrument is key to unlocking its “super-fat” analogue sounds.
What is the Stylophone S2?
The Stylophone S2 is a fully-featured, British-made analogue synthesizer. Unlike the smaller, plastic models typically associated with the brand, the S2 features a robust all-metal construction and a 37-note (three-octave) keyboard. It is designed for musicians who want the portability of a Stylophone but the sound quality and control of a high-end studio synth.
Inside the unit, you will find a 100% analogue signal path. This means the sound is generated by physical components rather than digital code, resulting in the warm, rich tones that analogue enthusiasts crave. Its compact size makes it an excellent addition to a live performance rig or a portable studio setup.
Key Features and Specifications
To get the most out of your instrument, it is helpful to understand the technical components that make the S2 stand out. Here are the primary features you will encounter:
- Dual VCOs: Two voltage-controlled oscillators provide the foundation of your sound, allowing for complex waveforms and detuned effects.
- Sub-Oscillator: This adds a lower octave to your sound, creating the “fat” bass tones the S2 is known for.
- 12dB/Octave Filter: A high-quality filter that allows you to shape the tone by cutting or boosting specific frequencies.
- LFO with Multiple Waveforms: The Low-Frequency Oscillator can modulate your sound to create vibrato, tremolo, or rhythmic pulsing.
- Internal Delay: A built-in effect that adds depth and space to your patches.
- CV/Gate Connectivity: This allows you to connect the S2 to other modular synthesizers or external sequencers.
Portability and Build
One of the most striking aspects of the S2 is its physical design. Measuring approximately 308mm x 120mm x 26mm and weighing less than one kilogram, it is highly portable. The all-metal case provides durability, while the printed circuit board (PCB) keyboard offers a smooth surface for the stylus to glide across.
Setting Up Your Stylophone S2
Getting started with the Stylophone S2 is straightforward, but there are a few steps to ensure you are getting the best sound quality possible. Follow these steps to prepare your instrument for play.
Powering the Unit
The S2 can be powered by batteries, making it truly portable. It typically requires four AA batteries. To install them, locate the battery compartment on the underside of the unit. Ensure you use high-quality alkaline or rechargeable batteries to maintain a consistent voltage, which is crucial for keeping analogue oscillators in tune.
Connecting to Audio
While the S2 has a built-in speaker for quick practice sessions, you will likely want to connect it to an external amplifier, mixer, or audio interface for recording or live performance. Use the 1/4-inch line-out jack located on the side of the device. If you wish to practice silently, you can also use the dedicated headphone output.
Using the Stylus
The stylus is your primary interface. It is tethered to the unit to prevent loss. When playing, hold the stylus like a pen and make firm, consistent contact with the metal keys on the keyboard. Unlike a traditional piano, the S2 uses a monophonic interface, meaning it plays one note at a time. This makes it ideal for lead lines and bass parts.
Basic Sound Design on the S2
Once you have the unit powered on and connected, you can begin shaping your sound. The S2 offers a variety of knobs and switches that control the analogue circuitry.
Tuning the Oscillators
Start by setting the main VCO. You can adjust the pitch and waveform to find a starting point. By introducing the second VCO and slightly detuning it from the first, you can create a thick, chorused effect. Adding the sub-oscillator will provide immediate weight to the low end, which is perfect for bass-heavy electronic music.
Adjusting the Filter
The filter is perhaps the most important tool for sound shaping. By adjusting the cutoff frequency, you can make the sound bright and piercing or dark and muffled. The resonance control (sometimes labeled as ‘peak’) adds a sharp boost at the cutoff point, which can create the classic “squelchy” sounds associated with acid house and funk music.
Using the LFO
The LFO can be assigned to modulate either the pitch or the filter. If you want a subtle vibrato, assign a triangle wave LFO to the pitch with a low depth setting. For more experimental sounds, use a square wave LFO at a high speed to create robotic, modulated textures.
Tips for Better Performance
To keep your Stylophone S2 in top condition and improve your playing experience, consider the following practical tips:
- Keep the Keys Clean: Because the keyboard relies on electrical contact between the stylus and the metal surface, oils from your fingers can occasionally cause “dead spots.” Wipe the keyboard down with a dry, lint-free cloth regularly.
- Calibrate the Pitch: Like all analogue gear, the S2 may drift in pitch due to temperature changes. Use the fine-tune knob on the back or side to align the instrument with other gear before you start recording.
- Practice Your Glide: The stylus allows for effortless glissando (sliding between notes). Practice moving the stylus smoothly across the keys to create fluid transitions that are difficult to achieve on a standard MIDI keyboard.
- Use External Effects: While the built-in delay is excellent, the S2 sounds incredible when paired with external reverb or distortion pedals. Experiment with your signal chain to find unique textures.
Troubleshooting Common Issues
If you encounter issues with your S2, most can be resolved with simple maintenance. If the sound is intermittent, check the stylus tip for debris or oxidation. Gently cleaning the tip with a very fine abrasive or a contact cleaner can restore connectivity. If the pitch seems unstable, ensure your batteries are fresh, as low power can cause the oscillators to behave unpredictably.
Finding Manuals and Resources
Because the Stylophone S2 was produced in limited quantities compared to the mass-market models, finding physical manuals can be difficult. Most users recommend searching for digital PDF versions of the original manual, which provide detailed diagrams of the internal signal flow. Online synthesizer communities and forums are also excellent places to find “patch sheets”—diagrams that show you how to set the knobs to achieve specific classic sounds.
Conclusion
The Stylophone S2 is a professional-grade instrument that offers a tactile and rewarding synthesis experience. By understanding its analogue architecture and mastering the stylus interface, you can create a wide range of sounds from vintage leads to modern bass lines. Its durable build and portable nature make it a versatile tool for any musician’s collection.
