About

MF

This app recreates a classic analog effects pedal, offering a voltage-controlled oscillator with variable waveshape and envelope follower. It allows for processing and modulation of various audio inputs to create unique musical sounds.

Highlights
  • Voltage-controlled oscillator (VCO)
  • Variable waveshape
  • Hard sync and frequency modulation
  • Envelope follower
  • Modulate VCO frequency with input dynamics
  • Mix VCO with audio input
  • AUv3 effects plug-in

The MF-107S Freqbox is a re-invention of Moog Music’s classic Moogerfooger MF-107S analog effects pedal. The MF-107 Freqbox, originally introduced in 2007, contained several complete modular synth functions: a voltage-controlled oscillator (VCO) with variable waveshape capable of being hard synced and frequency modulated by the audio input, and an envelope follower which allowed the dynamics of the input signal to modulate the frequency of the VCO. In addition, the amplitude of the VCO was controlled by the dynamics of the input signal, and the VCO could be mixed with the audio input. A direct descendant of the original Moog modular synthesizers, the MF-107 was adapted to process, modulate, and play with inputs ranging from guitar, voice, and synthesizer to any imaginable audio source. The MF-107 Freqbox has been meticulously recreated as the MF-107S, capturing not only the jagged, freaky sounds of the original, but also the organic way in which the parameters interact to create a musical playing experience. The MF-107S is an AUv3 effects plug-in that requires a compatible host or DAW to function.

About

QuadroSphere

This audio plugin allows musicians to sculpt immersive soundscapes by controlling stereo placement and effects across four distinct frequency bands. Create dynamic, atmospheric audio with automated movement and morphing between saved settings.

Highlights
  • 4 configurable frequency bands
  • Control stereo separation, level, and pan per band
  • Create and morph between 12 snapshots
  • Modulation control for automated sweeps
  • Per-band effects (Haas, Delay, Reverb, Chorus, Compressor)
  • Convert mono to pseudo-stereo
  • MIDI CC control

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.
