Behringer Dual Portamento CV Utility Module 297 — dual CV portamento module for modular synths

Behringer Dual Portamento CV Utility Module 297 is a compact Eurorack-compatible module that provides two independent CV portamento channels for modular synthesizers. It is designed to introduce smooth glide between incoming control voltages, allowing gradual transitions of pitch or other modulation signals. The module is intended as a utility building block for patching legato passages, expressive CV sweeps and subtle timing offsets in a modular rig.

Advantages

This dual CV portamento module offers independent control over two channels, enabling separate glide settings for different voices or modulation sources without occupying multiple module slots. Its compact form factor conserves rack space while integrating easily with standard Eurorack power and signal levels. The design focuses on simple, predictable behavior for live and studio use, ensuring consistent glide across a variety of CV sources.

Suitable for

• Smoothing pitch CV between successive note gates for legato lead and bass patches
• Applying glide to modulation sources such as LFOs or envelope outputs
• Creating slow, expressive transitions and pitch bends in modular performances
• Utility processing in compact Eurorack systems where space and independent channels matter

Key specifications

• Two independent CV portamento channels
• Compact Eurorack-compatible module size
• Controls for adjusting glide time per channel
• Handles standard modular control voltage levels
• Panel connectors compatible with common patch cables

How to use

Patch the incoming CV signal to one of the module's inputs and route the corresponding output to the destination module (oscillator pitch CV, filter cutoff CV, etc.). Adjust the glide control for that channel to set the desired transition speed between voltage steps. Use the second channel independently to process another CV source or parallel voice. The module can be integrated into existing patches to add legato behavior without changing primary voice modules.

Usage recommendations

For predictable results, patch pitch CV at standard volt-per-octave levels and set glide times while playing or sequencing the notes so you can hear the effect in context. Use the two channels to separate melodic and modulation glide tasks, and avoid routing high-frequency audio signals through the module to prevent unintended filtering of audio content.
