Herbs & Stones Solid Felt Desktop Stereo Multimode Filter

Solid Felt is a stereo multimode analog filter in desktop format.

Its name comes from the etymology of the words “stereo” and “filter”.
From subtle timbral variation to an all-encompassing sonic treatment, Solid Felt can be used in multiple ways to embellish or vandalize your sound bouquet:

• As two independent mono filters
• to give a stereo treatment to a mono signal
• to filter a stereo signal at the same cutoff frequency on the L and R channels
• As a mono 24dB/oct filter (placing the two filters in series)
• To synthesize sounds, via external feedback patching
• To extrapolate a CV signal from your audio input and use it to control any of its parameter or external gear
• As a stereo overdrive effect
• To bring line level signals to eurorack level

Features:

• 2x Analog multimode analog filters
• 2x 1/4″ jack high impedance inputs
• 2x 1/4″ jack low impedance outputs
• 8x 1/8″ jack eurorack compatible CV inputs
• 8x 1/8″ jack eurorack compatible CV outputs
• Input gain control to amplify incoming signals up to fuzzy territory
• mode control to select between lowpass, bandpass and highpass filter response (CV controllable)
• an envelope follower (normalled to input A) which is fed into a three stage clock divider
• a voltage controlled LFO with waveform blend control and two outputs 180° out of phase
• a voltage controlled LFO with rising and falling sawtooth outputs
