Hi,
Ive got quite a supprise when I tried to combind 4 hip~ filters in serie to get a 24dB/oct slope filter. It worked fine as long as there is a signal but when the signal fades the patch starts to consume alot of CPU power, like 50% or so, when there was a signal it did take just a few percent.
Regards Peter Lundén

Sounds like a denormal error to me. You could try to feed a tiny bit of noise~ to the filters to avoid it.
