Yes, my mod reduced the overall resonance, but from oscilloscope observations I could see that the waveforms, while still being flattened out when using high resonance on the filter, aren't being longer flattened out so much
like the synth does with the factory calibration, when using the same amount of resonance (not according by the slider's position but by the spectrum analyzer). So there's a real gain in sound's body and not only a mere change in the reso's slider range. That change in filter behaviour can even be immediately seen on the oscilloscope while doing the calibration, as stated previously:

This gain in sound's body is also present when using the filter without resonance. The first sound I made when I got the Jupe was a simple brass patch (without resonance), and I was surprised how it sounded better, fuller after doing the mod without doing any change to the patch itself. This also happened on other sounds without resonance I made, including basses, which are now punchier.
Keep in mind that this mod can be done according to everyone's taste, if one still wants an "intrusive" resonance just have to turn the trimmers accordingly. And restoring the synth to its factory settings it's just a matter to recalibrate it following the service manual's instructions.
So experiments can be done to reach everyone's ideal sound.

That it's true, maybe you read it on gearslutz, on this

nebula wrote:Same thing with the clicky envelope. Adjust your attack so it just disappears and you'll have roughly the fastest attack available on many other synths.
Yes actually there's a mod that prevents this clicking (by forcing a slightly longer attack time to shut up the clicks) but I don't want to do it, as very fast attack sounds are no longer possible with this mod and to restore the original status you have to re-solder in place the original capacitors (or components with the same values).
nebula wrote:The downside to all this is that all of the sliders are WAY more responsive than most other synths. Programming the JP-6 is an exercise in subtlety - if you really move those sliders a lot you are most certain to blow right past the sound you are looking for.
True, actually if the only benefit with this simple mod would be a mere change in the resonance's slider range I'd restore the synth to the factory tunings. But I could see and hear real (for me) improvements in the sounds, so I thought that sharing this could be useful for people who would their Jupes sounding more warm.
