Jps Harmonic Synthesizer [win]: Reason Re

The is a specialized Rack Extension (RE) for Reason, developed by Jiggery-Pokery Sound . It is a faithful software recreation of the RMI Harmonic Synthesizer , a rare mid-1970s hardware unit famously used by Jean-Michel Jarre on the classic album Oxygène . Core Concept: Additive Synthesis with a Twist

In this synth, each "harmonic" is not a pure sine wave but is actually quite rich in its own sub-harmonics, resulting in a raw, vintage, and slightly lo-fi character. Reason RE JPS Harmonic Synthesizer [WiN]

It models the original's digital harmonic generators but routes them through a fully modeled analog audio path, including voltage-controlled envelopes and a triple-output filter. Key Features The is a specialized Rack Extension (RE) for

A built-in effects section featuring a flanger, chorus (based on the Chenille Chorus Ensemble), and reverb. It models the original's digital harmonic generators but

While it captures the original's quirks (like "Up" and "Random" sequencer modes), it adds modern necessities like polyphony, velocity sensitivity, and 4-stage ADSR envelopes.

Unlike modern additive synths that might offer hundreds of pure sine wave partials, the JPS Harmonic Synthesizer uses 16 harmonic level faders per oscillator.

Every front-panel control can be automated within the Reason sequencer or controlled via CV (Control Voltage) on the back of the rack.
