The article, entitled "Harmonic Carousel: Unmasking the Echoes of Oberhausen, Black 3109 and Fold Processor," delves into the creative combination of select Eurorack modules to create a unique spectrum of electronic sounds, providing an overview of their features, practical uses, and groundbreaking sonic capabilities. The Erica Synths Black 3109 VCF/VCA, a combined lowpass filter and voltage-controlled amplifier classed around the AS3109 chip, overcomes distinct setbacks of previous modules—such as volume drop-off during resonance amplification—making it especially versatile in compact setups, with 1V/oct tuning for perfect keyboard tracking. The St Modular Oberhausen module, with its principal oscillators and modulation oscillators, provides a wide array of complex waveforms. With individual volume control for different waveforms and an additional blend mixer, the module showcases the potential to create diverse waveforms. Tiptop Audio's Fold Processor, a voltage-controlled wave multiplier, and sub-octave generator, aims at creating unique, artistic waveforms from more usual ones through a vintage diode design that adds odd harmonics, emphasizing the beautifully animated folding sounds. The cDVCA by Atovproject introduces groundbreaking technology inspired by class-D amplification. As the world's first VCA that tracks 1V/oct, the module's novel clipping method works exceptionally well for the generation of distinct distortions. While it can generate a simple square wave in its absence, the tone control enables the management of produced harmonics. Wrapping up the build, Big T Music's Rangoon, a reworking of Mutable Instruments' Rings, serves as the perfect 12hp companion module, highlighting the classic 'Rings into Clouds' combination in Eurorack modular with an exceptional design inspired by Blade Runner. This remarkable collection of modules guarantees a myriad of sonic explorations, whether you're after the sweetest harmonics or the grittiest glitches.
