PASSIVE TOOLS 2 is a versatile collection of passive utilities in 4 HP. It consists of 4 signal processors, each designed to perform a specific operation with the input signal. TAP is a pluck/decay envelope generator expecting gate or staircase signals. LPG is a DC-coupled passive low pass gate made with a homebrew optocouple (vactrol) usable to process both CVs and audio. BEND is a quirky transistor-based wavefolder/waveshaper-like sound processor. Finally, LPF is a simple RC low pass filter with 3 preset cutoff frequencies.
