So I bought a Jupiter 8 earlier this year....

A suggestion, how about comparing your real J8 with a virtual one?? Arturia have a free Jupiter-8V, how realistic it sounds is another matter but I would guess the functions are correct.

There's no way to keep the LFO lights off (the LFO is constantly cycling), but with the modulation sliders/switches turned down/off, the LFO shouldn't have any effect on the filter cutoff.

THAT'S good to know!

Thanks everyone, I've managed to get the sudden jumps to stop by using the LFO in the VCF section.

I'm sorry to say that my knowledge of how synths work is extremely basic, I bought the Jupiter because I heard it was one gigantic "sweet spot". Oh and I had a nice royalty cheque....

I'm going to have a mess around today and as a thank you I will post some pics and some clips.

Cheers guys.

I was actually comparing the jupiter 8 to Arturia's Jupiter 8V today. Running them simultaneously through the same audio interface and monitors. To my surprise the oscillators and filters sound identical. At no point could I differentiate between the two. It's the overboard effects they add in the demo patches which detract from the authenticity of the sound.

Nice! You have one of the most sought-after analog polysynths out there. Time to start learning what all those switches and sliders do.

You know, the Juno 60 you have has a lot of the same features (only simpler/fewer of them), such as that same LFO-VCF slider, so if you find the Jupiter daunting at first, familiarize yourself with basic synthesis concepts on the Juno first. With one envelope, one oscillator, and fewer options, it'll be easier to grasp the basics before you dive into the Jupe's extensive panel.

Right, and Sonic Project OPX sounds just like an OBX, but not really. Without getting into the dead horsey that is the analog vs. digital debate, I must say I did the JP8/AJP8V comparison too, and the real deal is an order of magnitude punchier, the oscillators drift a bit, the VCF is warmer,(think mid-range warmth) and is not so clean-sounding overall. I think part of it is the noise in the signal path, due to the unit's age. I just wish I could get some decent headroom out of it. It's much too dynamic to compress it to death.

Also worth mentioning is the interface, which is half the fun. I don't even use patches these days with my Jupe. It's all manual mode for me.

[justinvm]

but not really.

Yeah I totally agree, it's just an emulation.

I also compared them and I didnt find them to similar. The resonance was very diferent etc.

Jupiter-8 is nice, but its no fat b***h of an analog like an OBXa.

Diff'rent strokes for diff'rent folks. Myself, in a polysynth, I much prefer sultry, silky, sexy to fat b***h. Much better for the mix and my own personal taste. Maybe one day I'll have a change of heart and get a Korg Mono/Poly, then keep it permanently in unison mode.
