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.

BLEASS Multiband Compressor is the perfect tool for injecting loudness, power and punch into your mixes, stems and tracks. Whether you are creating music on-the-move on your iPad, producing your masterpiece in the studio, or doing both, BLEASS Multiband Compressor dispenses detailed precision control over your music's dynamics. One of the secret weapons of professional mix and mastering engineers, multiband dynamics processors have various advantages over conventional broadband processors. By separating your audio into three frequency bands, and processing each independently, BLEASS Multiband Compressor ensures that loud passages and transients in one frequency range do not impact on how the other bands behave. This eliminates the "volume pumping" effect often exhibited by broadband compressors, making BLEASS Multiband Compressor the perfect tool for processing drum kits, synths, pianos and – of course – full mixes and stems. The plugin works brilliantly with other sources too, from solo instruments to vocals and spoken voice. Unusually for a multiband processor, each of BLEASS Multiband Compressor's three bands features a dual stage dynamics processor. This consists of an Above stage that senses for and processes signals whose level exceeds the Above threshold, and a Below stage that senses for and processes signals that are quieter than the Below threshold. Additionally, each stage can operate as either a compressor or, by dialing in Ratio values below 1:1, an expander. Altogether this makes for phenomenally versatile control over the volume and loudness of your mixes, stems and parts. Another innovative feature of BLEASS Multiband Compressor is its flexible sidechain system. This allows you to choose which bands will key from the input signal in the normal way, and which will key from a filtered and/or external signal. This is ideal for corrective work such as controlling resonances, sibilances and other unwanted artefacts, but is also a fabulous creative tool, allowing for stylish ducking effects and ultra-deep dynamics control. Rounding things off, the plugin provides comprehensive output level and dry / wet balance control, along with a soft clipping feature that ensures overly-hot signals don't become nasty and harsh, but instead take on a classic valve-like saturation character. BLEASS Multiband Compressor stands out for its great sound, innovative features, versatile dynamics control, and exceptional efficiency. More information on https://www.bleass.com/multibandcompressor
