How would you configure and use [bob~] to demonstrate what the ladder filter fuss is all about? For some reason (inexperience? poor taste?) I keep returning to [vcf~].
Edit: after an hour or two of monkeys at the typewriter, I'd say that the 2 main differences from [vcf~] are the roll-off slope ([bob~] never completely mutes signal even when the cutoff freq is 8 hz) and the resonance sounds brighter and grittier (bob at resonance 3 sounds like vcf at q 22 to me). There's got to be more to it than that, right?
