GTEX4 – Gate Signal Expander
GTEX4 – Gate Signal Expander
The GTEX4 from Esm Sound is a versatile and highly useful gate signal expander, designed to enhance the flexibility of your modular system. When more gate signals are needed, the GTEX4 steps in to multiply and extend a single gate signal into four independent outputs, providing additional control and creative possibilities for complex modular patches. Its compact and efficient design makes it an essential tool for expanding the capabilities of any modular setup.
