(I seriously can't imagine ever being willing to pay more than about 1500 USD for it, however, in its current form)
I purchased a Jupiter 80 for £1550 second hand as I couldn't afford the full price. After using it, I find that it is worth every penny. You have to spend time with one to understand this, but it is hard as most stores won't lend you one!!;-) But I can confirm that it is seriously good. For the studio or the live player.

Can Jupiter 80 owners please help with a question:

In the new Integra-7 manual, I see a parameter called Stretch Tune Depth, which is supposed to alter pitch relative to equal temperament. I searched through Jupiter-80's manual, can't find it. Is it there but named as something else? Thanks.

As the Integra-7 includes a full-blown SuperNATURAL engine AND a full-blown PCM engine à la XV-5080/FantomX/G/etc. , the parameter "Stretch Tune Depth" is only existent in the PCM Synth engine and not in the SuperNATURAL engine derived from the new Jupiter series...

Is the Jupiter 80 able to do a convincing MKS-80 or Jupiter 8 recreation?

Is the Jupiter 80 better than the integra 7 due to its fx structure and polyphony?

Steve Fortner, long time musician and member of the Keyboard Magazine staff, mentioned in a video review that the VA synth in the JP-80 sounded darn close to a Jupiter-8. I've heard this from several musicians, as many as have said that no, it doesn't. But given how hard the folk around here are on ANYTHING virtual analog, I'd say this recommends it as good sounding. And from audio samples I've heard of the JP-80 synth tones soloed compared to a Jupiter-8, I find it to come very close, in fact, I rather like the 80 a bit more which could simply be a matter of having nice effects on board. And I like the variety of filter types. I have to reiterate that I haven't come within miles of one, as they're about as rare as the OASYS in stores, but the net has enough quality examples that I'm satisfied. And yes, you CAN get a good assessment of an instrument from net sources. I have way too much experience chasing down net samples and then hearing the real thing in person, so that meme about how nothing sounds the same online is bunk.

There is a caveat on that though. There is no hard sync as of yet, a weird omission on a Jupiter synth, or cross-mod.

Compared with the Integra, the advantage of the JP-80 is the insane 256 voice polyphony, and Live Mode performability. Most people also love the JP's synth action keyboard. It does have a good range of effects per part, but being a performance oriented keyboard, it's limited to four parts: Upper, Lower, Percussion and Solo. And effects are divvied up this way:

EFFECTS: 8 multi-FX (4 Upper, 4 Lower), 3 reverbs (Upper, Lower, Solo/ Percussion), 2 compressor-EQ-delay chains (Solo and Percussion), global 4-band semiparametric EQ.

The multieffects used to be parallel only, but with the latest update, I think you can do some MFX chaining, not that I think it would matter much with four effects per multi. And I believe the delays can also be configured as chorus. Because of the crazy polyphony, a lot of the synth "patches" - the equivalent of combis or performances on some synths - there are a lot of huge evolving layers slathered in effects with tinkly arpeggios running through them, and really overwhelm what the synth is really capable of as a traditional synthesizer.

The Integra-7 has the usual 128 voice polyphony, but is more focused in the kinds of sounds you expect from a Roland synth, so the huge evolvo-pads are a little less smothering. It's 16 channel multitimbral, and each part has its own multieffects feeding into an overall EQ/compressor/ambience, which Roland states gives you six of. I'm assuming "ambience" is a reverb of some type. While the JP-80 has some 4,000 patches on board, the Integra offers an insane 6,000 of them! With a category search to help you sift through them, you can probably find something that hits you in the pleasure center, or to use as the basis of a fresh patch. It's also heavily built around the traditional PCM rompler side, and includes twelve of the SRX expansions, which to me are superb sounding. Considering that many have been built by long time Roland sound designer Eric Persing of Spectrasonics fame, this comes as no surprise. You virtually "load" these four at a time to use in sound building.

Another aspect which is integral to the Integra - ba-dum - is the surround sound capability built in. And while the JP-80 gives you a basic stereo out and two aux outs, the Integra offers you ten outputs to take advantage of whatever outboard effects you have, as well as individual processing for surround sound or multi-channel production.

One drawback for the Integra-7 is the fact that to edit it, you need to use a SONAR DAW, which a basic version is included, or an iPad to program it, while the JP-80 has a marvelous touch screen.

It's a bit like comparing the JD-800 with the more potent JD-990 module. Each one has things to commend them, and it's a matter of which offers you more capacity for what you need.

using capital letters and emphatic exclamations ("yes"! Hallelujah!) is not going to disprove anytime soon the fact that the tube sucks at demoing top-notch synthesyzers.

[more about the "yes, you can" mantra in... er... 3 days and 1/2]

But please, go ahead and review an instrument you didn't event touch.

And indeed:

I just had the opposite experience concerning the Jupiter-80:

After watching and listening for about one year almost everything available on the web about the JP-80 after its release and reading the specifications and the user manual and parameter guide, I dismissed the JP-80 very much and wrote a lot of bad things about the JP-80 on other forums...

Even after having touched the JP-80 for just a few seconds for the first time in my local music store, I just didn't "get it" and left the store ignoring the JP-80.

But when I finally had the second chance to test the JP-80 in person for two whole days under perfect audio conditions, I had to realize my former ignorance and my huge failure...

So when I finally "got it", I had to realize that the Jupiter-80 is the most expressive and most organic, best sounding and most accessible synthesizer Roland has ever built to this day! It is in fact so good, that I finally even purchased TWO Jupiter-80!

Yes, but the JP-80 offers Ring Modulation and Wave Shaping instead.

Beside the virtual analog waveforms you can also choose from several hundred of sampled waveforms instead, where you find plenty of very good sync waveforms.

And don't forget that you have a THREE Oscillator subtractive synthesis with a distinct Filter, Amp and Modulation section FOR EACH single Oscillator available on the JP-80, which gives you an incredible wide array of sound design options!

Those statements of mine which you've destroyed in your quote ARE JUST PLAIN TECHNICAL FACTS. Are you a kind of Republican who denies scientific facts?

And believe what you want man, but only AFTER having tested the JP-80 for several days and after having done your own sound programming on it! I don't give a damn sh*t about your BELIEVE, but it is possible that I would care about your OPINION, based on real life experience with the real instrument!

I've just tested the JP-80 filter behavior concerning audible steps in the different available contexts, like:

-Synth edit mode
-Real time offset parameter control via the real time knobs or external controllers
-Real time control by the modulators like ENV and LFO
-Real time control via aftertouch and mod wheel

The JP-80 filters always react absolutely smooth in every situation! (BTW: This is not the case with the Integra-7.)

The following informations could be of interest as well:

Quotes from JUPITER :: Roland Synthesizer Global Official :

Authentic synth sounds — from classic vintage analog to modern digital

To faithfully recreate the unique sound of analog synths, we've meticulously analyzed the behavior of oscillators, filters, and envelopes that are unique to analog synths. In the new JUPITER series, a single synth tone comprises three OSC, FILTER, AMP, and LFO chains, which give you absolutely powerful synthesis control over a single tone. You also have access to ring modulation, WAVE shapes for creating complex tones, and the popular UNISON mode, which lets you overlay up to eight waves per OSC to create thick and fat analog synth tones.



Incredibly Smooth Analog Feel
Emulates the envelope behavior of an analog synthesizer
In an analog synth, the electric charge/discharge rate of the envelope rises and falls in a slightly curved line. The JUPITER-80 and -50 faithfully reproduce this attribute for all of its envelopes, including the oscillator, filter, and amplifier. By using this envelope to control the four LPF types, the resulting sound has an incredibly smooth analog feel.




Emulates the filter behavior of an analog synthesizer
The LPF plays an important role in shaping the tone. It can be used to cut elements from the sound, and can also be used to emphasize elements around the cutoff frequency with resonance. When you control the resonance in an analog synth, the cutoff frequency fluctuates, and signal levels below the cutoff frequency are affected as well. The entire filter changes organically as if it's alive. These changes occur due to the behavior of the analog circuits and the components used, such as resistors and condensers, which make up the unique sound of an analog synth.



Four types of LPFs with unique behavior
[JP-80, Jupiter-8, MiniMoog, Prophet-5]

The JUPITER-80 and -50 feature four types of LPFs. Each filter behaves differently, even if their cutoff and resonance parameters are the same. The LPF is personalized by its parameter settings and real-time control cutoff frequency and resonance.

Quote JP-80 Parameter Guide:

Analog Feel 0–127
Use this to apply “1/f fluctuation,” a type of randomness or instability that is present in many natural
systems (such as a babbling brook or whispering breeze) and is perceived as pleasant by many
people.
By applying “1/f fluctuation” you can create the natural-sounding instability that is characteristic of
an analog synthesizer.

The available processing power is shared in different ways in the Jupiter-80 and Integra-7.
The JP-80 (256 voices) has its full power available solely for the SN engine, why even the real time editing of the filters remains smooth,
which is not the case on the Integra-7 (128 voices), where filter steps are audible in SN edit mode.

The I-7 is therefore not recommendable for deep real time synth editing experiments in front of an audience, while the JP-80 is
capable to deliver in such a situation.
But those characteristics correspond to the different purpose and design of both instruments. (Performance Synth vs Sound Module)

The JP-80 has an intersection of possible sounds with the JP-8 , JP-6 (MKS-80), SH-101, Juno-60, Juno-106, D-50 and TB-303, etc.
where they are almost indistinguishable from each other.

But it is impossible to recreate every sound of the above mentioned synths on the JP-80 and of course vice versa.
And let's not forget that the JP-80 is offering not only the JP-80 Filter itself, but also a Jupiter-8, MiniMoog and Prophet-5 Filter, based on physical modeling!

I guess the new Jupiter Legacy Collection, which should be available soon, will confirm the above mentioned indistinguishability:

I've played ALL of them!

The coming Jupiter Legacy Collection offers sounds from those mentioned synths (JP-8 , JP-6, SH-101, Juno-60, Juno-106, D-50 and TB-303),
which are 1:1 recreations of some typical sounds of those classic Roland synths.

"Some people" already had access to some of those Legacy sounds and had the chance to compare them 1:1 with the original.
They are indistinguishable.
But people can decide for themselves after the release of the Legacy Collection...

What are you babbling on about? Do you actually have a JP-8, a JP-80 or an Integra?

You've written paragraphs and paragraphs of nonsense here. Surely you don't think you're qualified to comment about how an instrument sounds based on a YouTube or SoundCloud recording?

Here are some corrections to your comments about the Integra:

1) the Integra has 8 independent outputs, not 10. The XLR analog outs, the S/PDIF out, and the USB outs all reproduce the signal from the main 1/4" L/R analog outs

2) You do not need Sonar or an iPad to edit the Integra sounds. There is no editing at all that cannot be done on the Integra's own interface, which is, as Imentioned elsewhere on this forum, is extremely similar to the S-770 sampler and XV-5080 synth module

3) There is a global send-return based reverb with six different algorithms, and a global send-return based chorus/delay effect. There is no master compressor like there is in the Fantom series. Each part has its own independent insert effect. However the Integra does have multiple compressor effects available to the drum part, but these can only be applied to the drum part.

if you sample a jupiter 8 you have a sound that is indistinguishable from the same sound on a jupiter 8. big woop.

now if you take that same sound on the jupiter 8 and you move the cross-mod slider up 1 millimetre, then you have something that the jupiter 80 can never recreate.

ps i'm all for the legacy collection. who wouldn't be?

Those 1:1 rcreations of the Legacy collection are rather based on physical modeling than on sampling... But anyway in dedication to Ozy:

The Nyquist–Shannon sampling theorem

A signal or function is bandlimited if it contains no spectral density at frequencies higher than some bandlimit or bandwidth B. The sampling theorem asserts that, given such a bandlimited signal, the uniformly spaced discrete samples are a complete representation of the signal as long as the sampling rate is larger than twice the bandwidth B. To formalize these concepts, let x(t) represent a continuous-time signal and X(f) be the continuous Fourier transform of that signal:



The signal x(t) is said to be bandlimited to a one-sided baseband bandwidth, B, if

for all or, equivalently, supp(X) <= [-B, B].

Then the sufficient condition for exact reconstructability from samples at a uniform sampling rate fs (in samples per unit time) is:



The quantity 2B is called the Nyquist rate and is a property of the bandlimited signal, while fs/2 is called the Nyquist frequency and is a property of this sampling system.
The time interval between successive samples is referred to as the sampling interval:



and the samples of x(t) are denoted by x(nT) for integer values of n. The sampling theorem leads to a procedure for reconstructing the original x(t) from the samples and states sufficient conditions for such a reconstruction to be exact.
