If you want to emulate a SH-5 filter configuration (which is pretty
impressive
IMO), that would be 420 in HP mode without resonance into 440, and parallel
to this chain, a SEM-style filter (does it have a number yet?) in BPF mode.
420 and 440's CVs linked together, and SEM BPF manual only (;->)
(Not a 100% emulation, of course, similar.)
