F8-V2 has LFO’s, which are applied to highpass, bandpass or lowpass filters. Res 8 has a choice of a driven, nonlinear, multi-stage filter or formant filters that can be independently applied to each audio stream. Mod8 has a range of modulation effects like vibrato and ring modulation. It also has echo, reverb, sub-octave, and pitch shifting. The result is up to 8 different effects running all at the same time, each with its own settings and amplitude sequences. This layering gives unlimited options to create incredibly interesting effects, from intricate and wild effects, to rich, textured reverb, echo, chorus-type effects. The Collective 8 Audio Units come with hundreds of presets. Amplitude modulation patterns can be copied and pasted within each AU or between them.
The Mod8 and Res8 upgrade is free for registered F8-V2 users.
The Collective 8 Audio Unit Bundle is $45 and is available for OS X as a Universal Binary.
