The MF-102S Ring Modulator is a re-invention of Moog Music’s classic Moogerfooger MF-102 analog effects pedal. The MF-102 Ring Modulator, introduced in 1998, contained three complete modular functions: a Ring Modulator, a voltage-controlled Carrier Oscillator, and a voltage-controlled dual-waveform Low Frequency Oscillator (LFO). Designed by Bob Moog and his engineering team, the MF-102 was a direct descendant of the original Moog modular synthesizers, adapted to process, modulate, and play with inputs ranging from guitar, voice, and synthesizer to any imaginable audio source. The MF-102 Ring Modulator has been meticulously recreated as the MF-102S, capturing not only the spaced-out, retro-futuristic sound of the original, but also the organic way in which the parameters interact to create a musical playing experience. The MF-102S is an AUv3 effects plug-in that requires a compatible host or DAW to function.

QuadroSphere is a great tool for bringing an instrument to life by creating a soundscape with a constantly moving sound source. QuadroSphere splits the incoming audio signal into 4 distinct coloured frequency bands using the frequency bar. Each band has an associated coloured sphere allowing you to control the pan, stereo separation and volume level. You can use this plugin as a way to impose subtle control over stereo placement with little or no movement, or go crazy with random automation. Adding effects such as reverb or delay on a specific frequency band can help create a lush atmospheric swirling which surrounds the listener. This is great for musicians trying to create minimalistic ambient or tranquil soundscapes. You can create up to 12 snapshots of the sphere parameters and effect settings, then morph between them at a designated speed (measured in beats). You can also enable continuous randomization mode, and have full control over which spheres and control which parts are automated. You can also use QuadroSphere as a stereo splitter, using the additional outputs to add your own effects to band outputs. Key Features: ○ 4 Configurable frequency bands. ○ Control stereo separation, level and pan for each band. ○ Create up to 12 Snapshots. ○ Morph between various panning, width and frequency band levels. ○ Modulation control for automated sweeps around pan center. ○ Convert MONO signals into a pseudo-stereo image. ○ Per band Haas, Delay, Reverb, Chorus and Compressor. ○ Allows combined and individual per-band audio outputs. ○ Continuous randomized morphing of the stereo field. ○ Built in Preset Manager with drag and drop support. ○ Power and Solo for each band. ○ Controlable morph speeds. ○ Various animated transition modes. ○ Access most options using AU parameters or MIDI CC control.
