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. Features: Hybrid synthesis engine • Wavetable spectrum synthesis • Noise spectrum synthesis • Virtual Analog synthesis • FM and Ringmodulation synthesis Synthesizer details • Twelve wavetable spectrum oscillators per voice. • Morphing between two wave/filter sets. • Waves contain up to 256 partials. • Hand drawn filter structure. • Spectral noise generator using hand drawn filter structure. • Ten major sound parameters each with independent poly LFO and envelope modulators. • Real time parameter control using two X/Y touch pads, the tilt sensors of the iPad and MIDI Controllers. • Monophonic or polyphonic with up to 16 voices. • 300 factory presets, unlimited user presets can be shared.

*** Note *** Although mKer can run as a stand-alone app, the recommended way to use it is as an AUv3 plugin from inside a suitable AU Host app that supports MIDI Processors such as AUM, Audiobus, Cubasis etc. Please also note that mKer is a MIDI app/plugin. That means that it does not produce sound itself - it needs to be connected to an audio source that can receive MIDI. mKer is a versatile, multi-output MIDI step sequencer with an extensive range of features. These include: - 8 MIDI outputs - 64 Patterns - 16 Lanes (aka tracks) per Pattern - Independent number of Steps (1-32) and Step Size (1/64-256 beats) per Lane per Pattern - Every step can play either a single note, an interval (2 notes) or a chord (3 or 4 notes) - Lane Step parameters: Play Cycles, Skip Cycles, Play Offset Cycles, Pitch, Velocity, Probability, Offset (can be used for ‘swing’ like effects), Repeat (rachet) and Gate - A flexible Editor that includes a step entry keyboard, parameter sliders and a variety of options and utilities designed for to make the workflow intuitive and fast - 32 Clips with 1-8 Steps per Clip, 1-128 repeats per step (every clip step has one pattern) - 3 Play Modes: Pattern, Clip, Sequence (all Clips) - A Performance tab with 10 fully assignable MIDI sliders, a 12-snapshot bank and morphing function between the snapshots... - MIDI step input and real-time recording - 12-track beat generator with six genres, density, intensity and GM beat mapping ... and more!
