Copperhead is an AUv3 digital subtractive synthesizer plugin inspired by the vintage synthesizers of the early 80s. It offers exciting features like multi-note polyphony and a built-in arpeggiator, providing users with a range of integrated audio effects to explore. This app includes a custom String Machine and allows you to design custom waveforms, enhancing your creative options. With support for oscillator sync and various cross modulation effects, you can use FM synthesis to transform simple waveforms into something much more dynamic and engaging.

At the core of Copperhead are two oscillators. They support traditional waveforms such as sine, square, sawtooth, and triangle, as well as advanced types like SuperSaw and Trapezium. You'll also find pulse width modulation and a customizable string engine, giving you the power to create your own oscillator types.

The Voltage Controller Filter in Copperhead allows you to work with several types of filters, including LP, HP, BP, and Notch filters. You can configure these filters in series or parallel, adding to your sound design flexibility. One unique option is the Formant filter, which lets you sweep your cutoff to create interesting vowel-like sounds.

Copperhead features twin LFOs with capabilities for random modulation and one-shot functionality. In addition, it supports Cross, Ring, and FM modulators, together with low and high shelf filters for more refined sound shaping.

One standout feature is the integrated audio gate. This allows for stuttering audio generation right from the start, giving your music an extra punch. Combine this with effects like Chorus, Overdrive, Delay, Reverb, and Auto Pan/Tremolo, and you gain substantial control over your sonic landscape.

To further enhance your creative output, Copperhead includes a 32-step sequencer. You can work in both mono and poly modes, providing direct control over various synth elements, which makes crafting rhythms and melodies straightforward.

Managing your sounds is easy with the built-in Preset Manager. It groups presets into banks and categories, and it supports drag and drop for effortless import and export of presets. You can even access your favorite sounds through a special popup menu or a quick search feature. Copperhead comes loaded with over 550 built-in presets that cover nearly every instrument category you might need.

This AUv3 plugin is compatible with various digital audio workstations (DAWs), including AUM, Cubasis, GarageBand, and Loopy Pro. Copperhead offers a powerful platform for musicians and sound designers, making it an excellent choice for anyone looking to create captivating music. With its intuitive design and vast array of features, it sets you up for countless hours of musical exploration.
