Biquad constant changing cut-off frequency using Trill

Keyi

Hi all, is there a way to controlling the cutoff of a lp-filter using the Biquad library in Bela? I found the link https://www.earlevel.com/main/2012/11/26/biquad-c-source-code/ in a previous post, there is a "SetBiquad" function to do that. Is it achievable in Bela?

there is an example to use a potentiometers to use the cutoff of a Biquad filter here https://github.com/BelaPlatform/Bela/blob/dev/examples/Audio/variable-filter/render.cpp . It should be easy to use a Trill as a control input instead.
