The hybrid synthesis algorithm on which Addictive Pro is based provides you with efficient means for easy control of complex sounds far beyond usual sound synthesis methods: Addictive Pro provides you a with unique form of Wavetable oscillators. These Wavetables are generated from the harmonic content and the free digital filter structure entered by the user. The sound of up to 12 of this Wavetable oscillators is then further refined with a classic analog filter available in several 24dB and 12dB forms. For the optional noise part of the sound you can use the same sophisticated digital filter struct as for the wavetable oscillators allowing for a vast variety of ever changing noisescapes. The intelligent sound and rhythm randomizer can be applied to different sound aspects separately for really useful sound design and inspiration. A four part polyrhythm Arpeggiator creates complex rhythmical structures with a touch of a finger.

Popsicle is a Multi Effects Processor built around 2 independent stereo effects engines each having access to a total of 24 different effect algorithms. Effect engines can be used in series or parallel configuration or split between stereo channels where one is affecting the left channel while the other one is affecting the right channel respectively. Popsicle features a powerful XY Pad capable of controlling one or more fx parameters per axis. XY motion can be recorded and played back in sync with the host tempo allowing for highly dynamic effects. In addition, a advanced mode unlocks a fully featured mod-matrix with an additional LFO and Envelope Follower allowing for even more dynamic effect combinations and performances. Included Effects: - Lowpass Filter - Highpass Filter - Bandpass Filter - Morphing Filter - Formant Filter - Comb Filter - Echo - BPM Delay - Short Delay - Reverse Delay - Stutter - Chorus - Flanger - Phaser - Tremolo - Auto Pan - Vibrato - Bitcrush - Distortion - Fuzz - Pitch Shift - Plate Verb - Hall Verb - Mod Verb Supports: - Standalone - AUv3
