Inspired by the pinnacle of analog synthesizers, the mighty Yamaha CS-80, UNSTABLE is in no way intended to be a CS-80 emulator but still probably closer to the real hardware than anything out there.
A modern go at the famous Yamaha CS-80 Synthesizer.
UNSTABLE features two synthesis layers, each offering a noise, sawtooth, and pulse wave oscillator, with adjustable pulse width and variable speed pulse width modulation. Unlike the Yamaha CS-80, the level of each oscillator is adjustable, allowing for free mixing of the waveforms, which are closely modelled after the original.
The CS-80 features two state-variable filters in series, which allow for a unique subtractive sound synthesis, unlike most common synthesizers. In UNSTABLE, the high-pass filter is modelled after the original; I put a little more beef into the low-pass filter, however, providing a vaster range of musical harmonics.
The Yamaha CS-80 features the most musical ring modulator ever built, and I did our best to model it as closely as possible, with its own analog-style attack and decay envelope modifying the modulation speed.
Use the innovative on screen ribbon controller to pitch bend your sound up to an octave.
The full version (not the beta) will feature polyphonic aftertouch, just as the original hardware did.
The full version of UNSTABLE will feature a sophisticated 16 step arpeggiator with variable note and modulation values.
A dedicated drive circuit adds analog warmth and subtle harmonic distortion for loudness and crisp presence that cuts through your mix without sacrificing dynamics.
UNSTABLE features the popular effect engines of DarkStar Reverb and Delay, as well as the luscious WingMen Chorus, to bring your sound to the next level. Imagine a CS-80 with something along the JUNO-60 Chorus and Blackhole reverb.
