FX Expression Generator

The Cooper FX Expression Generator is a multi-output expression controller designed to provide dynamic modulation control for effects pedals, modular synthesizers, and electronic music gear. This device features four independent and assignable expression outputs, each with selectable operation modes. Output modes include Auto, for continuous cycling modulation; Tap, which sets modulation rate via a tap tempo footswitch; Trigger, for a manual sweep where modulation amount is determined by the footswitch hold duration; and Latch, which maintains the last modulation value upon footswitch release. All outputs can be set to run different modes simultaneously, enabling complex, evolving signal control across multiple compatible devices. **Features:** - Multi-output expression controller with four assignable expression outputs - Supports Auto, Tap Tempo, Trigger, and Latch modulation modes per output - Tap tempo footswitch for setting modulation rates - Compatible with effects pedals, modular synthesizers, and other gear featuring expression or CV input - Enables independent or simultaneous mode operation for versatile control - Compact interface with soft-touch main footswitch
