ARF

The ARF (Attack Release Filter) by Dwarfcraft Devices is an envelope filter effect pedal designed for creating experimental sounds on electric guitar, synthesizer, and bass. The pedal features adjustable attack and release controls, allowing for a wide range of envelope filter sounds, from far-out synthy tones to more familiar wah-type sounds. The envelope's range is determined by the knobs on the face, while the activation of the envelope and the duration of the sustained peak are controlled by a foot switch or CV gate signal. The envelope boasts an extensive range, from quick clicks to multi- measure swells and drops. The envelope is directly wired to an aggressive low pass filter with adjustable resonance, capable of self-oscillation. The filter cutoff can also be controlled via CV input. Additionally, the filter can be overdriven via the "drive" knob for a familiar stomp box sound, and there are settings that create pitch-shifting glitch effects. The pedal is powered by a 9V DC adaptor (not included) and features dimensions of 143 x 118 x 40mm. It also includes CV inputs for filter frequency and trigger gate, as well as an envelope output for passing the envelope control voltage on to external devices. The ARF is a versatile and feature-laden device suitable for a wide range of filtering and envelope following needs.
