The Behringer 1033 dual envelope generator module brings the legendary 2500 series sound to Eurorack for bold sonic creativity. With two independent envelope generators, the 1033 lets you sculpt expressive contours and movement. Dial in envelope shapes from short and punchy to long evolving drones. Whether you're creating funky grooves or cinematic soundscapes, the 1033 stimulates your imagination.

Vintage 2500 Series Reborn for Eurorack

Inspired by the original 1970s System 2500 modular, the 1033 authentically recreates the highly distinctive sound. Like the originals, it uses all-discrete transistor circuitry for rich, warm tone. The 1033 puts that coveted vintage vibe into a standard Eurorack module, making modular synthesis accessible. Use it to add vintage character to modern setups or as the start of a new modular journey.

Create Iconic Acoustics With Dual Envelope Generators

With two independent envelope generators, the 1033 provides deep sound shaping. Tweak the 10 controls on each channel including Gate Delay, Attack Time, Decay Time, Sustain Level and Final Decay Time. Craft percussive transient effects or slowly evolving drones. With a range of 0-10V, you can create subtle nuances or dramatic sweeps.

Manual and External Control Options

For flexible control, each envelope generator has a Manual Gate button to trigger it. There are also Gate and Trigger inputs to connect external keyboards and modules. In Single mode, the Gate input starts the envelope cycle. In Multiple mode, the Trigger input re-triggers it when a gate is present. Use the four outputs per channel to route the envelopes to other modules in positive and negative polarity.

Easy to Integrate Into Any Setup

Designed for Eurorack, the 1033 neatly fits into standard cases. Just connect the power, mount it with the included screws and integrate into your system. Add vintage envelope shaping to modern setups or build a system around the classic sound. Either way, the 1033 makes modular synthesis easy, inspiring and fun.
