I am really enjoying some of the filter abstractions I have found here, but they are quite CPU intensive so I am looking for good externals. So far the ones that sound good only accept message rate signals to their control inputs. Please recommend filter externals with signal rate inputs, at least for cutoff. Preferably LP/HP/BP/Notch and EQs would be nice too. Thank you all!

well, biquad~ of course, if you know how to handle it for different filter types.

but take care with fast signal rate modulation.

Thanks for the reply but I don't think biquad~ can accept signal rate inputs, only message rate. Or am I missing something?

oh pardon, it does not even have any inputs... i would have bet it is the same external as in maxmsp. :/
