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.

RM-1 Wave Modulator RM-1 is a multi purpose audio effect designed around various types of modulation. Featuring a built-in carrier oscillator, multimode filter, envelope follower and low frequency oscillator, RM-1 creates new sounds by combining carrier waveform and the audio input in different ways. Types of modulation: - Ring Modulation (virtual analog) - Ring Modulation (digital) - Amplitude Modulation - Phase Modulation (DX-style FM) - Frequency Modulation (linear) Overview: - Built-in carrier oscillator with variable wave-shape (sine->square) - Built-in multimode Filter (LP, HP, BP) - Built-in Envelope Follower and LFO Connectivity: - Standalone (MIC, USB audio) - IAA / Audiobus - AUv3 Plugin
