The Multi Burst Envelopes is a 12HP Eurorack module designed to generate evolving bursts of repeating envelopes, turning simple modulation into complex rhythmic movement. Each burst can contain between 1 and 40 envelopes, with selectable or CV-controlled shapes that can even change step-by-step as the sequence plays.

Envelope width, timing and repetition are all voltage controllable, letting you stretch, compress or skew bursts in real time. An internal LFO or external clock sets the pace, with support for irregular clocks and polyrhythmic behaviour when both are used together. The slope control lets bursts build, fade, or stay level across a sequence, adding dynamic variation.

With one-shot and retrigger modes, manual clocking, and full CV control over every function, it's a powerful way to generate intricate modulation patterns without complex patching.

Includes original box.
