The JP-8V allows for splits and layers.

Synthesizer aficionados have long desired a software emulation of Roland’s classic eight-voice Jupiter-8, and the original developers actually took a sort of sideways stab at it when they released their hardware-dependent VariOS-8 a few years ago.

However, this wasn’t terribly convincing. Fortunately for us, Arturia’s offering is a different beast. The company have already made a name for themselves with some cracking software emulations of classic synths, though it should be said that a couple of their recent releases have been just a touch disappointing. With the Jupiter-8V, though, they’re firmly back on track. This synth is a cross-platform, 32-voice instrument that can be used standalone or as a plug-in. And all the major formats are supported.

On the surface, it looks much like the hardware on which it’s based. It sports a pair of oscillators per voice, a dual filter design and standard ADSR envelopes. There’s a pair of LFOs onboard and, as you would expect on a modern instrument, some built-in effects processors. An arpeggiator has been thrown in for good measure.

These features can actually be found in any number of synthesizers, but the Roland Jupiter-8 wasn’t just any synthesizer. Even polyphonic instruments were a rarity in 1981, but the Jupiter went further still by being multitimbral. It was also one of the first synths to offer splits and layers across the keyboard, and Arturia’s emulation shares this ability. This enables the creation of deep, complex sounds that can be nothing short of huge.

In fact, even if you don’t do any layering at all, the Jupiter-8V is capable of some seriously massive timbres. If these aren’t enough, you can always use the unison function. This takes you from massive to practically galactic – trance fans are going to eat this thing up.

Oscillators

So the basics are all here, but it’s the little things that make the Jupiter stand out. You’ll find cross-modulation between the oscillators, for example, and you can also sync the oscillators for those ever-popular 80s leads. VCO2 can also be switched between normal and low-frequency modes. Plus, those oscillators offer six different wave shapes between them, including noise and modulatable pulse waves.

Once you’ve selected your waves, you can mix them and send them through the dual filters. You get a 6dB non-resonant high-pass filter and a low-pass filter with a selectable slope (12 and 24dB) and a resonance slider. Neither filter self-resonates - but neither did those on the real thing. The filter can be modulated by the LFO, keyboard and Envelope 2, in both positive and negative directions.

Sounds

Simply, it’s superb. Arturia have outdone themselves with the filter. It sounds warm and alive and reacts smoothly to real-time tweaking. The Jupiter-8V’s modulation sources include the aforementioned pair of four-stage envelope generators and two LFOs, though you have to open up the Modulations page to get to the second one.
