Folktek Alter
Seven DSP effects with CV-controlled chaos and color
16 HP Eurorack module
Folktek Alter is a stereo DSP effects processor for Eurorack featuring 7 unique, meticulously designed effects selected via capacitive touch pads. The module provides stereo inputs with independent level/gain controls, a wet/dry mix knob, a variable filter, and two independent effect parameter controls (X and Y) that map differently depending on the selected effect. A unique clock control adjusts the DSP sample rate for lo-fi degradation effects. All main parameters have CV inputs for voltage-controlled modulation. Mono input is automatically made stereo within the DSP. Available in two versions (Alter 1 and Alter 2) with entirely different effect sets. 16HP, +12V: 160mA.
