Sweep is what started it all.
What started as a Max Patch in 2018 eventually turned into this (and is Lese’s first ever plugin). Utilizing the same algorithms that sound designers use to create shephard tones / risset filters, Sweep uses a bunch of filters to make your sound feel like it’s rising (or falling) endlessly.
In Sweep’s case, the left and right channels can be split and controlled separately for a more complex, stereo aware sweeping effect.

Intuitive Control
Instead of controlling how the filters behave over the frequency spectrum with a bunch of complicated controls, Sweep keeps it simple; Drag the “factor” handles like you would with a graphical EQ, and the filterbank will follow the curve it makes.

Random is cool
Sweep has a smooth random noise generator built-in that can nudge the filters a bit higher or lower depending on how the noise is feeling at that moment. Change the Phase knob to adjust what kind of action occurs where, and increase the Complexity value to bring the random movement from slow and subtle to fast and complex.

This rather unremarkable filter was designed for manual (or automated) filter sweeps.
The cutoff covers the whole audio range (and then some). The resonance goes from none to fairly soft self-oscillation. The filter will morph from lowpass to notch to highpass.

An additional bandpass response can be cross-faded with the morph results. The final wet signal can further be cross-faded with the dry input. Additional output level trim is provided for convenience. Using a MIDI controller is highly recommended.

For random knob tweaking, the Q range can be limited to “safe” settings with maximum resonance setting mapping to 75% of the “full” range. With higher drive settings you should expect some (or all) of the resonance replaced with true-stereo distortion.

In practice, it might not be totally useless as sound-design tool and with low to moderate drive settings it can also serve most “utility filter” duties. Experiment.
