Description
The 4ms Company Spectral Multiband Resonant Filter is an indispensable tool for musicians and sound designers looking to explore the vast possibilities of modular synthesis. This tunable 6-channel bandpass filter and resonator is designed to split your audio into a rich tapestry of frequencies, each channel offering dedicated controls to sculpt and refine your sound. The integration of quantizable frequency settings across 11 tone scales and pitch CV following ensures that your creative vision is seamlessly realized with precision.
Each channel is equipped with a level fader, CV input, and a lock button, giving you hands-on control over your sonic landscape. The included envelope follower outputs per channel and dual pitch inputs (1V/oct.) provide further modulation possibilities, allowing you to shape and animate your music dynamically. With a rotate encoder capable of transposing all bands within the defined tone scale, the 4ms Spectral Multiband Resonant Filter invites you to dive into experimental territories with ease.
The morph and spread controls, alongside stereo input and output capabilities, ensure your sound is as expansive or as focused as you desire. Whether you're crafting intricate soundscapes or pushing the boundaries of your sonic experiments, this resonant filter offers a comprehensive suite of features to elevate your modular setup.
