Continua is a professional synthesizer for iPad, built around a single idea: everything should move. Three oscillators with five modes each — Virtual Analog, Additive, Supersaw, Supersquare, and IXA — give you a palette that runs from warm analog warmth to aggressive digital textures to sounds that have no easy name. Stack 64 sine waves. Detune five sawtooths simultaneously. Explore phase modulation borrowed from a synthesizer most people have never heard of. The oscillators are just the beginning. Continua's filters don't switch between types — they morph between them. Low pass becomes band pass becomes high pass in a continuous sweep, with resonance and two- or four-pole slope selectable at any point. Two filters running in series or parallel, each one a moving target. Modulation is where Continua earns its name. Nearly every parameter is a destination. Every knob can receive up to five simultaneous modulation sources — envelope generators, flexible multi-point envelopes, four shapeable LFOs, sample and hold, and a random source that gives each voice its own personality. Right-click any knob to connect a source. The routing is as deep as you want it to be. New in version 1.2: the Genetics panel lets you evolve your patches through an interactive mutation tree. Start with any sound, explore branches of subtle variations, and drill down into whatever catches your ear. The arpeggiator adds eighteen patterns — from standard ascending runs to Brownian motion and probabilistic rests — all synced to your DAW tempo. Four new oscillator modes expand the raw material available from the ground up. Full MPE support means Continua responds to every dimension of expression from a Linnstrument, Osmose, Roli Seaboard, or any MPE controller. Or play it with a standard keyboard and automate everything else. Works as an AUv3 plugin in Logic Pro, AUM, Cubasis, Drambo, Garage Band, and any AUv3-compatible host. iPad only.

RingsFX is an AUv3 plugin based on the famous Mutable Instruments Rings, one of the most dedicated and fully-featured Physical Modeling Eurorack modules ever created. At its core is a resonator that needs to be 'excited' or 'strummed' by MIDI input, noise, or external audio excitation. RingsFX emulates vibrations of structures simulated by 3 different synthesis techniques that can be plucked or process external signals: Modal Synthesis, Sympathetic Strings, and Inharmonic Strings. Traditionally, Rings was only monophonic but used a unique approach to polyphony that allowed the previous note to 'ring' out and decay while a new note was played. Rings FX provides these same modes (Mono, Duo, and Quad), but expands it with a true Polyphonic mode. RingsFX also expands the capabilities of the original engine by adding support for velocity sensitivity and MIDI MPE mode. The new polyphonic mode allows RingsFX to play up to 12 notes of true polyphony, depending on the settings. Doing so requires RingsFX to use multiple Rings resonators, but the more true polyphony you use, the more processing power it requires. Running in the traditional Monophonic, Duophonic, or Quadrophonic modes may be preferred in order to keep CPU usage under control. RingsFX has 7 modes in total, by combining the 3 basic modes with additional properties such as chords or specially tuned reverbs. The original hardware also had a secret 'Easter Egg' mode, which in RingsFX is simply calling 'Synthesizer' mode, rumoured to be based on one of the early Korg synthesis methods. This mode supported a number of mutable effects which now work on in all resonator modes. RingsFX also has a Mod-Matrix which allows you to combine the built-in LFOs and FEGs to great effect by manipulating parameters and mutable effects in realtime. Finally, RingsFX can be loaded as an AUv3 effect plugin. Set the Exciter Source to 'INPUT', and you can pass any audio through RingsFX and use this audio as an external exciter. For example, it can be used to great affect on a drum beat to create some crazy rhythms. Use the Output Mix to combine the original audio with the synthesised resonator output to create some stunning effects.
