Vox FX includes 39 different preset formant filter types plus a user defined mode. Each filter in the Vox FX plugin has a sound of its own.

The basic concept is that the filters morph from one setting to another. Some of the filters, the Complex State filters, even morph between more than two settings and there are filters which morph in an alternating and quantized way. In this case a morph means that the settings are not cross-faded using volume mixing. Instead the formant regions move in the frequency domain and the volume of each formant region changes.

• 39 formant filters plus a user defined mode.
• Frequency (Freq) - sets the base frequency of the formant filter.
• Pan - controls how much the sound should move between the left and right channel as the LFO sweeps.
• LFO with Rate, Depth, Sync, Phase, Shape (Sine/Random/Pulse).
