Furia 4-Pole Ladder Filter + VCA

Olivella Modular Furia

Rich, sweet, and resonant signal sculpting is just a knob turn away with Furia from Olivella Modular, a 4-pole ladder filter with integrated transistor VCA that provides vintage tone with modern control. At the core of Furia is a discrete transistor filter based on the low pass filter found in the E-mu 2100, delivering this classic spectral sculpting tool in a fully discrete design that imparts vintage warmth galore. This is fed into an onboard VCA with variable CV response, providing a feature-packed voice shaping tool in a compact package—just add an oscillator, and enjoy classic subtractive synthesis par excellence.

Furia's furious force derives from its formidable range of gain available, which allows you to saturate the signal around 9 o'clock on the Input Level control. The input level and resonance settings are highly interactive, allowing for plentiful sweet spots and unique characters. Flip the VCA's x10 input switch to boost the signal into screaming acidic territory, ideal for distorted basses and leads that melts through a mix with ease. The VCA and VCF sections can also be used independently, while the normalled connection between Amp CV input and filter frequency control enables seamless LPG-style operation. You can also inject other signals post-filter and pre-VCA with the Amp In input, ideal for adding in additional high or low content to compliment your filtered tones. If you're looking for vintage flavor in a compact and convenient design, Furia from Olivella Modular is here to bring the heat.
