KORG 900PS Specification

The KORG 900PS is a vintage analog synthesizer renowned for its rich sound and expressive capabilities. Released in the 1970s, this monophonic synth offers a unique blend of features that cater to both seasoned musicians and vintage synth enthusiasts. At its core, the 900PS employs a single voltage-controlled oscillator (VCO) that delivers a robust range of tones, seamlessly adjustable from deep basses to piercing leads. Its sound is further shaped by a voltage-controlled filter (VCF), which provides dynamic resonance and cutoff frequency modulation, allowing for a wide array of sonic textures.

The synthesizer includes a built-in preset sound bank, which offers a selection of pre-programmed sounds that can be easily accessed and modified. Users can further personalize their sound through the 900PS's modulation capabilities, which include an envelope generator with adjustable attack, decay, sustain, and release settings. This enables nuanced control over the articulation and dynamics of each note.

Additionally, the KORG 900PS features an expressive aftertouch keyboard, which responds to the player's touch pressure, allowing for real-time modulation of sound parameters such as vibrato and filter frequency. This feature enhances the instrument's expressiveness and playability, making it a favorite among performers seeking a more tactile interaction with their instrument.

With its classic design and sturdy build, the KORG 900PS remains a sought-after piece of equipment for those seeking authentic analog sound. Its combination of user-friendly controls and expressive features makes it a timeless addition to any music studio setup, offering a distinctive sonic character that continues to inspire musicians across various genres.
