Re: [PD] No voltage-controlled lowpass filter?

Hi, Is vcf~ (which is bandpass) the only available type of signal-controlled (smoothly-changing) filter? Doesn't the voltage-controlled version of lop~ and hip~ exist? Is it for a mathematical reason? (i.e. impossibility to implement in a relatively simple way) Or is it because it is

hello, there is a lot of discussion about filter in this list. if you wish to build filter with vanilla object, you can build yours with pole~ and zero~ objects. you can also use biquad~ object. you can also use expr~ to make an equivalent of my bq~ object and use my abstraction to compute
