GATE1 is an open source envelope generator designed specifically for gate and volume control in music production. It offers a flexible multi-segment editor that allows users to create and shape dynamic envelope patterns with precision. The plugin supports up to 12 different patterns, each triggered by MIDI notes, enabling intricate rhythmic and melodic control over sound shaping.

The envelope editor includes several drawing modes such as erase, line, saw up, and saw down, making it easy to craft complex envelopes. Users can adjust point types including hold, curve, s-curve, and stairs to fine-tune the envelope’s behavior. GATE1 supports tempo synchronization as well as LFO rate settings in Hertz, providing flexible timing options that adapt to different musical contexts.

Additional features include smooth attack and release controls, waveform displays both before and after processing, and a global tension control that influences the overall envelope shape. The plugin also offers MIDI trigger modes to ensure seamless integration with MIDI controllers and sequencers. GATE1 provides a powerful and intuitive toolset for producers looking to enhance their sound design workflows with precise envelope modulation.
