A modern go at the famous Yamaha CS-80 Synthesizer.

ANALOG OSCILLATORS
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 modeled after the original.

FILTERS
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 modeled after the original; the low-pass filter, however, features a Moog-style ladder filter with the capability to self-oscillate, providing a vast range of musical harmonics.

RING MODULATOR
The Yamaha CS-80 features the most musical ring modulator ever built, and we did our best to model it as closely as possible, with its own analog-style attack and decay envelope modifying the modulation speed.

RIBBON CONTOLLER
Use the innovative on screen ribbon controller to pitch bend your sound up to an octave.

ARPEGGIATOR
UNSTABLE will feature a sophisticated 16 step arpeggiator with variable note and modulation values. The arpeggiator is functioning, however, all options are not fully implemented yet.

DRIVE
A dedicated drive circuit adds analog warmth and subtle harmonic distortion for loudness and crisp presence that cuts through your mix.

EFFECTS
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.
