HoRNet FilterSolo is a high-quality resonant filter designed for creative sound shaping and design. It combines a digital filter core with analog front-end and back-end emulation, delivering rich, warm tones and realistic distortion when driven hard. This makes it an ideal tool for adding character and depth to your audio signals while maintaining precise control over tonal qualities.

The filter features four modes: low pass, high pass, band pass, and band stop, each available with 12dB or 24dB slopes. Cutoff frequency and resonance can be independently adjusted and modulated, offering extensive sound sculpting options. Two envelope followers with customizable attack and release times allow dynamic modulation of these parameters, while two LFOs provide additional modulation sources that can be synchronized with the host tempo or run freely, creating evolving and animated effects.

FilterSolo also includes analog-style saturation and hiss, which can be toggled on or off separately, giving users control over the character of the sound. Compatible with major plugin formats on both Mac and Windows, it supports 64-bit systems and offers multiple LFO waveforms for diverse modulation possibilities. This combination of flexible modulation, rich analog emulation, and multiple filter types makes FilterSolo a powerful addition to any audio production setup.
