If you are a fan of synthesizers, chances are you have heard of the Roland Jupiter series. These iconic synths have been used by countless musicians across genres and decades, from pop and rock to techno and ambient. But how did the Jupiter series come to be, and what makes them so special? In this blog post, we will explore the history of the Roland Jupiter, from its humble beginnings to its latest incarnations, and highlight some of the technical details that make these synths stand out.
The Jupiter-4: The First Polyphonic Roland
The Jupiter series began in 1978, when Roland released the Jupiter-4, also known as the JP-4. This was Roland’s first polyphonic synthesizer, meaning it could play more than one note at a time. The JP-4 had four voices, each with a single VCO (voltage-controlled oscillator) that could produce four waveforms: sawtooth, square, pulse, and noise. The VCO was followed by a VCF (voltage-controlled filter) that could switch between low-pass and high-pass modes, and a VCA (voltage-controlled amplifier) that controlled the volume of the sound. The JP-4 also had two envelope generators, one for the filter and one for the amplifier, and an LFO (low-frequency oscillator) that could modulate the pitch, filter, or pulse width of the VCO. The JP-4 also featured a built-in arpeggiator, a pitch bend lever, and a memory section that could store up to eight patches.
The JP-4 had a solid, warm, and meaty sound that was well suited for basses, leads, and pads. It was also relatively affordable and easy to use, making it popular among musicians who wanted a polyphonic synth without breaking the bank or spending hours on programming. Some of the artists who used the JP-4 include Duran Duran, Depeche Mode, The Human League, and Gary Numan.
For devices with serial numbers up to 800800, the configuration includes four OTA (Operational Transconductance Amplifier) stages, each featuring selected BA662 chips with FET transistors serving as buffers. Devices with serial numbers higher than 800800 utilize four OTA stages integrated into a Roland IR3109 chip. The IR3109 filter chip shaped the iconic Roland sound and became a key component in their subsequent synthesizers: Jupiter-6 (configured as two 12dB State-Variable-Filters), Jupiter-8, Juno-6, Juno-60, JX3-P, MKS-30, MKS-80 (until Revision 4), MC202 and the SH-101.
The Jupiter-8: The Flagship Synth of the 80s
In 1981, Roland released the Jupiter-8, or JP-8, which was a major upgrade from the JP-4. The JP-8 had eight voices, each with two VCOs that could produce the same waveforms as the JP-4, plus a sub-oscillator for extra low-end. The JP-8 also had a more advanced filter section, with a 12 dB/octave or 24 dB/octave low-pass filter that could self-oscillate, and a non-resonant high-pass filter. The JP-8 also had two envelope generators, one for the filter and one for the amplifier, and a single LFO that could produce four waveforms: triangle, square, sawtooth, and random. The JP-8 also had a more sophisticated modulation section, with cross-modulation and sync options for the VCOs, and a bender that could control the pitch or filter frequency. The JP-8 also had a larger memory section, with 64 patches and eight patch preset pairs that could load two split or layered patches at the same time. The JP-8 also had a keyboard split function, that allowed the user to play four voices on the left half of the keyboard and four voices on the right half, and a polyphonic unison mode, that stacked all 16 VCOs on one note, but divided them if more keys were pressed. The JP-8 also had a more reliable tuning system, and a DCB (digital communication bus) interface that allowed it to connect with other Roland devices.
The JP-8 had a lush and versatile sound that could cover a wide range of sonic possibilities, from rich and smooth to bright and edgy. It was also one of the most expressive and playable synths of its time, with a responsive keyboard and a plethora of controls. The JP-8 was Roland’s flagship synth for the first half of the 80s, and was used by many influential artists, such as Michael Jackson, Prince, Toto, Journey, Queen, ABBA, Giorgio Moroder, Jean-Michel Jarre and many many more.
The Jupiter-6: The MIDI-Enabled Synth
In 1983, Roland released the Jupiter-6, or JP-6, which was a more affordable and compact version of the JP-8, with some added features. The JP-6 had six voices, each with two VCOs that could produce the same waveforms as the JP-8, plus a sub-oscillator and a noise generator. The JP-6 also had a similar filter section, with a 12 dB/octave or 24 dB/octave low-pass filter that could self-oscillate, and a non-resonant high-pass filter. The JP-6 also had two envelope generators, one for the filter and one for the amplifier, and a single LFO that could produce four waveforms: triangle, square, sawtooth, and random. The JP-6 also had a similar modulation section, with cross-modulation and sync options for the VCOs, and a bender that could control the pitch or filter frequency. The JP-6 also had a memory section, with 48 patches and eight patch preset pairs that could load two split or layered patches at the same time. The JP-6 also had a keyboard split function, that allowed the user to play three voices on the left half of the keyboard and three voices on the right half, and a polyphonic unison mode, that stacked all 12 VCOs on one note, but divided them if more keys were pressed. The JP-6 also had a more advanced arpeggiator, that could be synchronized with external equipment via a clock input.
The JP-6 had a similar sound to the JP-8, but with some differences. The JP-6 had a slightly thinner and brighter sound, due to the different filter design and the lack of sub-oscillators on the JP-8. The JP-6 also had a more metallic and aggressive sound, due to the addition of the noise generator and the cross-modulation feature. The JP-6 was also one of the first synths to have MIDI, which made it more compatible with other devices and easier to integrate with a computer. The JP-6 was a popular synth among musicians who wanted a polyphonic synth with MIDI and a distinctive sound.
The JP-8000/JP-8080: The virtual-analog Icon.
The Roland JP-8000 is an important milestone in the world of synthesizers, renowned for its rich, analog-like sounds and its role in shaping electronic music. Introduced in 1996, it was among the first synthesizers to offer virtual analog modeling, allowing musicians to recreate the warmth and presence of classic analog synths in a digital format.
One of the standout features of the JP-8000/JP-8080 is its Supersaw waveform, a unique sound that became a staple in trance music and continues to influence genres today. This waveform consists of seven detuned sawtooth waves, creating a lush, full-bodied sound that can fill a room with its harmonic richness. The synthesizer boasts a hands-on interface with 38 knobs and sliders for real-time control, making sound design both intuitive and enjoyable3. It’s equipped with two oscillators offering seven waveforms, two LFOs, a ring modulator, and various modulation options, providing a vast sonic palette for creative exploration3. The JP-8000 also features a ribbon controller and an arpeggiator with various patterns, adding to its performance capabilities.
