A Synth Like No Other
UNSTABLE SYNTH takes the legendary Yamaha CS-80 and propels it into the modern era. This powerhouse instrument delivers the iconic warmth and expressiveness of the original, combined with innovative new features for limitless sonic possibilities. Whether you’re crafting lush pads, evolving textures, or cutting leads, UNSTABLE offers an unparalleled synthesis experience.
Authentic Analog Oscillators
At the heart of UNSTABLE are two synthesis layers, each loaded with noise, sawtooth, and pulse wave oscillators. With adjustable pulse width modulation (PWM) and free mixing of waveforms, you get unmatched flexibility—something even the original CS-80 couldn’t achieve. These oscillators are meticulously modeled after their analog counterpart, ensuring every note resonates with warmth and depth.
Advanced Filtering for True Subtractive Synthesis
The dual state-variable filter architecture captures the essence of the CS-80 while expanding its sonic range. UNSTABLE features: ✔ Authentic High-Pass Filter – Modeled directly from the CS-80 for pristine tonal shaping.
✔ Moog-Style Low-Pass Ladder Filter – Capable of self-oscillation, unlocking rich harmonics and deep, resonant textures.
Musical Ring Modulator
The CS-80 had one of the most expressive ring modulators ever built, and UNSTABLE brings it to life with incredible precision. Featuring its own analog-style attack and decay envelope, the modulation speed is dynamically controlled for otherworldly metallic textures, evolving drones, and rich, detuned harmonics.
Revolutionary Ribbon Controller
Take control of your sound like never before with the on-screen ribbon controller. Effortlessly pitch-bend up to an octave and add organic expressiveness to your playing, just like the original hardware.
Next-Level Arpeggiator
UNSTABLE features a 16-step arpeggiator with variable note and modulation values. Perfect for rhythmic movement, evolving textures, and dynamic performances, the arpeggiator provides infinite creative potential. Additional advanced functions are on the way!
Analog Drive for Extra Punch
Shape your tone with the built-in drive circuit, delivering subtle warmth to rich harmonic distortion. Whether you need delicate saturation or an aggressive edge, UNSTABLE ensures your sounds cut through the mix.
Studio-Grade Effects
Enhance your sound with a powerful effects suite inspired by some of the most iconic processors: ✔ DarkStar Reverb & Delay – Perfect for lush atmospheres and spatial depth.
✔ WingMen Chorus – Inspired by the JUNO-60 Chorus, adding rich stereo movement.
✔ Blackhole-Style Reverb – Cinematic, deep, and immersive.
