This prolific Mac Audio Units developer has two entries in our list, the first, Flow, being a sequenced flanger that sounds superb and is immense fun to use.
Each step in the sequence (you can have up to 32 of them) hosts controls for setting the Flanger Gate (bypass), Flanger Time, Modulation Intensity and Modulation Envelope shape for that step, with a range of global adjustables establishing the base flanger and envelope settings within which the per-step parameters operate.
As is the Sinevibes way, although the interface enables a good amount of user control, the calibration of uneditable under-the-hood parameters is also a major factor, and the net result is the most rhythmically agile, creative flanger we’ve ever had the pleasure of working with.
