Basically, cutoff is the treble control, resonance adds harmonics and emphasis to the filter envelope as it is triggered.
If you use basic waveforms (saw triangle square), this is how you shape the sound in the frequency spectrum. For instance you can't do a gong sound without the resonance. If you back off the cutoff (fewer high freqs) and increase the resonance, you should start to get overtones. As you increase the resonance the overtones will start to dominate the sound and the fundamental will disappear. It will start to sound like it's underwater.
If you apply this to a complex sound such as a voice or instrument sample, you will either remove the high freqs (with loss of loudness) or make it sound like it's coming over a telephone (or worse). Perhaps a useful application is to apply a slow LFO to the filter cutoff (try this with drums) with the resonace set so that the sound doesn't start to oscillate (and ruin your mix) as more high freqs are added.
The thing about the 760 filter is that is will self-oscillate, meaning the annoying whistling sound you get when you crank the resonance full. Back off the cutoff to make the sound more manageable. Also keep the velocity sensitivity of the filter down a bit till you get a handle on it.

Use the resonant Filter in combination with the ADSR envelope or LFOs.
You are able to morph a "thudd" into a "foomp"
or bring life to synth-pads with a moving Filter.
You have to bring Dynamics into play, not just adding resonance to a fixed Filter.
What makes a Jupiter's Filter powerful is it's envelope.

Some of the S-50 images that I've gotten online are not being read by my
sampler. So far I've only found a few, but I have not gone through all of them. 2
that I have found so far is 501.7 and 507.5. Do I need to do something else
beside floppy image them? Does anyone have a copy that they've been able to use
on their S-50?
Sorry for the newbie question but, what¹s all that fuss with resonant
filters ? Why do people are so much after them ? To my ears when I¹m
tweaking my S-760, all it makes is a weird sound in the treble (I even tried
on an E-Mu), so I can¹t see at all how it could make a bass sound sounds
³better² for when i¹m playing some bass patch in Sxx format and playing with
the filter resonance, it¹s doesn¹t sound any better or phatter...or maybe i
dunno how to do it.
Thanks
