I want to use this filter because it sounds good and has much less CPU overhead that making filters with biquad~ / czero~ etc. But the cutoff & resonance inputs are via a [pack]ed set of floats. What's the best way to use this if I want to modulate the filter with LFOs or envelopes that are at signal rate? Just use [snapshot~] and a fast [metro] and perhaps a [line] to smooth it out? Or should I find a better filter external?
