ARF - Attack Release Filter (hopefully when these catch on, we can just leave it at ARF.)
A combination Attack/Release envelope generator and resonant filter. The envelope is triggered by tapping the left footswitch, rather than depending on some "pick dynamic" detecting circuit which ALMOST NEVER WORKS. (and you can't put it in the middle of a note's decay, or modulate a drone with it)
Depressing the switch engages the attack stage of the envelope. Holding your foot as long as you like is the decay stage (That's like a bonus, it's not even in the name!) sustaining the envelope at whatever DEPTH you have dialed in on the knob of the same name. Releasing the switch will engage the Release stage of the envelope, and your filter will ramp back down to it's knob-set-position.
The filter section has a familiar array of controls. Cutoff, resonance, and drive. You can use the drive knob to boost a quiet signal, tame a loud one, and often add grit to your input.
The filter can also be coaxed into a very rude self oscillation. Of course.
We have also included control voltage inputs (1/8" euro standard) for the filter cutoff, and envelope trigger. There is also a CV out from the envelope generator, so you can modulate other gear with the ARF if you so choose.
"Why don't you use 1/4" jacks for CV like Moog?""Because space is the final frontier."

Eau Claire, WI – March 30, 2015 – ARF stands for Attack, Release, Filter. This pedal comes filled with good synthy goodness! The Attack/Release envelope’s range is determined by the knobs on the face, while the activation of the envelop and the duration of the sustained peak are controlled by a foot switch or CV gate signal.
This means much greater control than typical "envelope follower" style filter pedals, which have a habit of triggering at the wrong times. The envelope boasts an absurd range, from "click-and-it's-over" to multi-measure swells and drops. It can also be sent out of the pedal for integration with other CV compatible gear.
The envelope is wired directly to the filter, an aggressive low pass filter with enough "extra" on the resonance to get some self oscillation. The filter cutoff can also be controlled via CV input. The filter can be over-driven via the "drive" knob for a familiar stomp box sound. There are even settings that create pitch shifting glitch effects! LET’S GET FUNKY.
Pedal will retail for $250 and will be ready to ship April 1, 2015.
