yaleD is a dedicated reverse delay audio effect, with full support as an Audio Unit (AUv3) plugin extension. Please note that while it works as a standalone app, it is designed to be used from other host audio apps such as GarageBand, AUM, Audiobus 3, Cubasis, etc! A reverse delay effect continuously listens then plays back reversed chunks of the audio input depending on the delay time, feedback and filtering settings. Can be used for both obvious or subtle effects depending on the setup. Since a reverse delay is sensitive to positional sync as well as delay time, the reversals are appropriately synced to the host transport timeline when playing back and using the beat-based delay time. Or the Hold Time button can be used to both sync and set the delay time manually by pressing and releasing it at the appropriate time. - Complete control over input gain, and independent wet and dry output levels. - Feedback with cross-pan and both low-pass and high-pass filtering. - Two available repeat behaviors when using feedback: one keeps all repeats reversed, while the other alternates each repeat reversed then forwards. - Delay time specified either in milliseconds, or as beats (with 1/16th note resolution) synced to host tempo. You can also specify the maximum delay time (up to 20 seconds!) in the settings to control the per-instance memory usage. - Can apply a delay time scaling offset to the second channel for interesting stereo effects. - Optional Tape effect when changing delay time. - One-Shot mode for doing triggered records and single reverse playback. Great for playing a solo in and reversing just what you want to hear. The hold/record and replay buttons can be controlled with MIDI bindings. - All parameters are exposed to the AU host so that you can apply automation or MIDI bindings from the host - Easy to use resizable plugin interface optimized for host apps on both iPhones and iPads. Made for fingers!

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.
