Copperhead is an AUv3 digital subtractive synthesizer plugin developed by Limelight Software. Drawing inspiration from vintage synthesizers of the early 80's, Copperhead offers a modern twist with full polyphony, an integrated arpeggiator, and a range of built-in effects.

At the core of Copperhead are its two oscillators, supporting traditional waveforms like SINE, SQR, SAW, and TRI, as well as SuperSaw, Trapezium, and user-defined waveforms. The app also features pulse wave modulation and oscillator sync for added flexibility.

Copperhead's Voltage Controller Filter includes LP, HP, BP, and Notch filters, as well as the unique Formant filter for creating vowel-like sounds. The plugin also offers twin LFOs with random and one-shot functionality, as well as Cross, Ring, and FM modulators.

One standout feature is the integrated audio gate, allowing users to generate stuttering audio effects. Combined with effects like Chorus, Overdrive, Delay, Reverb, and Auto Pan/Tremelo, and the ability to specify effect order, Copperhead provides extensive sound control.

Additionally, Copperhead includes a 32-step sequencer with mono and poly modes, and a built-in Preset Manager for easy import/export of presets. AUv3 compatibility ensures seamless integration with popular DAWs like AUM, Cubasis, GarageBand, and Loopy Pro.

Copperhead is a powerful synthesizer plugin that combines vintage inspiration with modern features, making it a versatile tool for musicians and producers.
