$139
A function generator and ADSR envelope generator based on the classic Serge Slope Generator, capable of working as a slew limiter, envelope generator, LFO, or audio-rate oscillator with separate exponential/logarithmic controls for rise and fall.
$169.99
The Changeling is an envelope filter based on the classic Seamoon Funk Machine from the 1970s, keeping the original circuit while implementing refinements that dramatically improve usability across bass, guitar, and keyboards. A JFET input buffer circuit ensures clean signal handling, with optimized decay, attack, frequency response, and filter driver settings.
€19.99
A Eurorack PCB and front panel DIY kit for a voltage-controlled ADSR envelope generator based on the CEM3310/AS3310 IC, with CV inputs for each envelope stage.
$110
A voltage controlled Attack Release/Attack Sustain Release envelope generator and slew rate limiter with a gate delay function, featuring rise and fall time control, tune CV for looping envelopes, and an end-of-cycle output.
$299
The AF-9 is an optical envelope filter modeled on the vintage Mu-Tron III, offering funky, liquid, vowel-like auto-wah effects with Low Pass, Band Pass, and High Pass filter types.
$193.99
An envelope-controlled resonant filter pedal for guitar and bass whose center frequency moves based on playing dynamics, similar to an auto-wah. Features BIAS, MELLOW/BRIGHT switch, SENSITIVITY, and DECAY controls.
Envelope filter effect from a legendary vintage synth. Create truly unique sounds for guitar, bass, and keyboards with fat sounding filter effects.
Building on years of envelope filter know-how, the Spectrum Intelligent Filter marries the legendary tones of vintage envelope filter pedals with modern ingenuity.
A Eurorack envelope generator module using a 555 timer configured as a Schmitt trigger to generate an exponential ADSR-style envelope, with a range switch and hysteresis input buffering.
A single-channel attack-release envelope generator Eurorack module with a range switch, in a compact 2HP format.
A dual-channel attack-release envelope generator and slew limiter Eurorack module with independent attack and release controls per channel, useful for percussion patches or slewing sequenced voltages.
