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.
Octaves
This audio plugin offers a unique spectral sound design experience by dividing the audio spectrum into octaves. It provides a retro-scientific approach to sound manipulation, reminiscent of classic avant-garde electronic music studios.

Octaves is our latest collaboration with Berlin-based composer and YouTuber Hainbach. It is a filter plugin designed to take apart the audio spectrum in spreads of octaves, allowing for unique and enchanting spectral sound design effects. Octaves gives you a retro-scientific approach to sound that echoes the timeless productions created in the BBC Radiophonic workshop or the WDR Studio für Elektronische Musik by the Avantgarde masters, and modern places like Willem Twee, Strøm, and Hainbach’s own laboratory.
