Dual Sergesian slope generator with logical crossfade - Used

• Used Befaco Rampage Eurorack module
• Dual slope generator inspired by Serge/Buchla circuits
• Two voltage-controlled integrators that can be used as function processors
• Ideal for ramps, envelopes, slew limiters, portamento, and glide
• Analog logic functions, slope detectors, and advanced outputs

Befaco Rampage (Used) is a used Eurorack module designed to offer a flexible and powerful approach to generating and processing ramps, envelopes, and control signals. Inspired by classic Serge/Buchla function generators, Rampage integrates two independent sections into a single module, expanding its creative possibilities with analog logic functions, slope detectors, and advanced outputs.

Befaco Rampage: Dual Slope Generator for Modular Synthesis

Built around two voltage-controlled integrators, Rampage can be used as a function generator, slew processor, ramp source, or tool for transforming square waves into ramp waveforms. This architecture makes it extremely versatile within a Eurorack system, whether for rhythmic applications or complex modulations.

Portamento, glide, and CV processing with the Befaco Rampage

When applied to pitch CV signals, Rampage allows you to achieve portamento or glide effects, making transitions between notes smoother. It can also be used for basic low-pass filtering and to shape control signals in a dynamic and musical way.

Analog logic functions and advanced outputs for creative patches

Befaco Rampage’s “patch-programmable” approach allows you to combine the two sections in various ways, paving the way for complex modulations, intricate envelopes, cyclic behaviors, and logical interactions between signals. This module is particularly well-suited for those seeking a flexible, high-performance function processor for their modular system.
