Other people have asked for the ability to apply LFOs (including S&H) to parameters in other blocks. In your case, you are asking for an LFO or S&H to be applied to the cutoff frequency in a filter. But why stop there? Phaser and flanger sweeps, delay time and feedback, distortion pedal gain, etc., could all benefit from a universal approach to LFOs. This assignable/programmable ability is one of my favorite features of the Empress Zoia, which I still keep on my pedalboard next to my QC. Give these requests a look. I would also like to see this kind of functionality built into CorOS: > [@LFO,GATE,ENV assignable on module parameters](https://unity.neuraldsp.com/t/lfo-gate-env-assignable-on-module-parameters/5310): > > Hi to everyone, i’m ask to the Neural guys if we can wait for us on the next patchs, somethings like LFO,ENVELOPE,GATE assegnable on a module parameters,like the pedal expression. It would be a great implementation, it would allow to create very elaborate effects, without creating new modules. Thanks a lot. > [@ZOIA/Modular Like Utility Blocks (LFOS, Envelopes/Followers, Sequencers, CV...)](https://unity.neuraldsp.com/t/zoia-modular-like-utility-blocks-lfos-envelopes-followers-sequencers-cv/4134/3): > > This would be absolutely HUGE! As a Zoia user myself the modular nature of that thing makes it incredibly flexible. Would make this thing very tough to beat and you’re right, the UI would lend itself very nicely to it. > [@Feature request: Random/sample/hold on LFO parameters](https://unity.neuraldsp.com/t/feature-request-random-sample-hold-on-lfo-parameters/5236/2): > > A vinylizer type effect that adds warbling and a dusty, dark feel would also be welcomed! --- _[View the full topic](https://unity.neuraldsp.com/t/sample-hold-filter/9206)._
