Behringer 297 Dual Portamento CV/Utilities Eurorack Module

Behringer 297 Dual Portamento CV Utilities is a Eurorack module designed for modular synthesizer systems. It enables portamento control and control voltage mixing for modular users, supporting signal routing and pitch glide workflows. This makes it ideal for Eurorack setups where CV signal shaping and voltage generation are critical.

The module combines dual CV mixers, portamento controllers, and constant voltage generators within a single Eurorack unit. It provides multiple CV inputs, attenuators, and selectable outputs to integrate with patch-based modular signal paths.

Within a modular system, it can be used to control pitch glide between notes or distribute control voltages to multiple destinations. Its mixers and voltage outputs support routing to oscillators, filters, and other modules where CV signal control is required.

Key Features

• Dual Portamento Controller: Two independent portamento circuits for controlling glide between control voltages
