Petrit and list,
The resonance filter makes a more ow sound when you play with it. I
don't have a S-760, however on my Roland jd-800 and Minimoog synthesizers,
the resonance filter adds quite a bit to the sound. you don't want to add
too much. Try opening up the resonance filter a bit and opening and closing
the overall filter, you should notice a difference in sound. Talk soon.
