Sound & Modulation Character
At its core, Blue Cat’s Flanger delivers a traditional flanging topology with a wide expressive range.
Dial in smooth, musical movement or push it into sharper, more alien textures using feedback and phase options.
Selectable sine or triangle LFO shapes give you control over the feel of the sweep, while in-phase or out-of-phase feedforward and feedback paths let you shape the tone from soft and wide to tight and metallic.
The stereo spread control is a standout. With a single knob, you can transform mono flanging into a wide, animated stereo effect that moves around the listener and adds real spatial depth.
Workflow & Performance
Despite its simplicity, Blue Cat’s Flanger is built to professional standards. It supports full MIDI control and automation with MIDI Learn, updates parameters smoothly without zipper noise, and shuts down processing automatically when fed silence to keep CPU usage low.
The interface is skinnable, resizable, and customisable, making it easy to integrate into any setup.
