Korg Prophecy (1995-1998) Synthesizer

A monophonic synthesizer using physical modeling and Korg's MOSS synthesis system, released in 1995.

Overview

The Korg Prophecy is a monophonic synthesizer released in 1995. Korg marketed it as a "solo synthesizer." It has a 37-note keyboard with both velocity and aftertouch sensitivity, so it is built around playing control. It was one of the earliest commercial synthesizers to use physical modeling and virtual analog synthesis, running on Korg's proprietary MOSS (Multi Oscillator Synthesis System) DSP engine. That lets it emulate acoustic and analog sounds with dynamic realism. The unit is noted for its light but sturdy construction and its oiled walnut wood end panels, which set it apart from other mid-90s synths.

Specifications

Synthesis Type	Physical modeling based on MOSS DSP

Keyboard	37 keys, velocity- and aftertouch-sensitive
Display	40 x 2 LCD
Dimensions	740 mm (w) x 280 mm (h) x 100 mm (d)
Arpeggiator	5 preset patterns, adjustable velocity and gate length, 3 directions: up, down, random

Design

The Prophecy uses Korg's Open Architecture Synthesis System (OASYS), built around the MOSS DSP platform. That allows multiple synthesis types in a single instrument. The design centers on real-time expressiveness, with extensive control over oscillator behavior and articulation. It has twelve oscillator sets - each one a pair of oscillators - so the sound can be layered even though the synth is monophonic.

Context

The Prophecy was introduced in 1995 at a price of $1595. That put it in the premium range as a solo performance synthesizer, focused on synthesis innovation rather than polyphony or workstation features. It was praised as an early leader in analog and acoustic modeling. One source said of its capability, “It's not a new synth - it's seven!” referring to its diverse sound engines.

Market

A listing on Equipboard notes a current market price from $225.79, which reflects its status as a collectible mid-90s digital synth. One unit was described as non-functional with quiet output, but that refers to a single used example and not general reliability.
