Molli Looper is a realtime stereo effect for looping and filtering. Intended mainly as a live performance tool, no preparation is needed to trigger loop recording - input is constantly recorded in the background to be triggered whenever it is needed.   Loop timing is synced to host clock, and can be adjusted from multi-bar loops right down to 16th note drills.   The looped or unlooped audio is then passed though a lowpass -> neutral -> highpass resonant filter, based on a 4 pole ladder design for lush analogue style sound.   You can use Molli Looper either as iOS Standalone app or as AUv3 plugin. FEATURES: - Combination of looper and stutter/freeze - Continuous recording: instant recording/looping - Runs in sync with host clock - Jumps to meaningful places in the recording: "Snap to grid" - Grid: 1/16, 1/8, 1/4, 1/2, 1, 2, 4, 8, 16, 32 beats - Ability to scroll through the recording - Lowpass/highpass resonant filter - Long Tap XY keeps filter position - Limiter/booster effect - Momentary Mode - Tap on Molli Looper icon for basic information

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.
