HY-MBMFX Multi-Band Effect

The free version of HY-MBMFX is a 3-band FX unit with a single FX slot on each band. The plugin comes with a long list of available effects (20 in total), including a variety of filters, delay effects, bitcrushers, distortion, modulation effects, a compressor, and even a reverb. The included effects sound very good, as is expected from an HY-Plugins release. Each slot also features input and output volume controls, stereo width and pan adjustment, a brickwall limiter, and mono, solo, and bypass switches. The top part of the GUI hosts the preset manager, A/B testing and undo/redo buttons, whereas the two knobs on the bottom part of the interface allow the user to adjust the frequency band split points.
