Copperhead is an AUv3 digital subtractive synthesizer plugin which draws its influence from the vintage synthesizers of the early 80's. Only now we have multi-note polyphony, a build in arpeggiator, and a host of integrated audio effects. Copperhead features a custom String Machine, the ability to design your own custom waveforms, as well as supporting oscillator sync and various cross modulation effects. Cross modulation is a type of FM synthesis which can be used to morph simplistic waveforms into something far more aggressive and interesting. At the heart of Copperhead are its two oscillators, which support all your traditional waveforms (SINE,SQR,SAW,TRI), as well as SuperSaw, Trapezium, and other user definable types. The app features pulse width modulation and supersaw, as well as a customisable string engine and the ability to create your own oscillator types. The Voltage Controller Filter supports the usual LP, HP, BP and Notch filters in series or parallel configuration, as well as a couple of unusual ones like Formant which allows you to sweep your cutoff to create interesting vowel sounds. Copperhead also features twin LFO's with random and one shot functionality. It also supports Cross, Ring and FM modulators, in addition to low and high shelf filters. One of the great features is the integrated audio gate, which allows you to generate stuttering audio right out of the box. Combined with effects such as Chorus, Overdrive, Delay, Reverb and Auto Pan / Tremelo, and the ability to specify effect order, you have a lot of control over your sound. If that wasn't enough, we also include a 32 step sequencer, with various mono and poly modes with direct control control of various synth elements. We have a built in Preset Manager which groups presets into banks and groups, which supports drag and drop for easy import/export of presets. You can also access your favourites from a special popup menu, or via the built in quick search facility. Copperhead now ships with over 550 presets which cover just about every instrument category you would ever need. ○ AUv3 compatible. ○ Up to 16 note polyphony. ○ 7 Oscillator wave types. ○ Sub Oscillator. ○ PW/PWM on SQR and TRP waveforms. ○ Supports SuperSaw with MIX and DETUNE. ○ XMod / Ring and FM modulations. ○ Osc Sync. ○ 6 types of VCF filter. ○ Low and High shelf on output. ○ Built in compressor. ○ Chorus, Delay, Overdrive, Reverb and Auto Pan effects. ○ Built in Audio Gate. ○ Preset Manager with Bank/Group/Preset section. ○ Supports drag and drop to import/export presets, groups and banks. ○ Supports web transfer of presets. ○ 32 step arpeggiator. ○ More than 550 built-in presets. NOTE: This is an AUv3 plugin which was designed to be hosted in DAW's such as AUM, Cubasis, GarageBand, Loopy Pro etc.

• Enhances Mix Loudness and Adds Harmonic Warmth • Full-Band and Two-Band Clipper in a Single Plugin • Quick, lightweight, and designed for effortless flexibility! • Precise Visual Metering for Fast Peak Control • Knee Curve Adjustment, from Super Soft to Hard • Shape Control of the Harmonic Profile • Dry/Wet Mix for a Natural, Balanced Sound • Low Latency with Optional Oversampling • Advanced Responsive Design, portrait and landscape views • Universal Purchase: AUv3 for iOS (iPad/iPhone), macOS and Vision Pro FAC Clipper is designed to enhance your mix's loudness and add signature harmonic warmth. While it is based on a similar DSP architecture to the Clip processor in FAC Punchlab, it takes a different approach to clipping control, featuring an advanced user interface with precise metering to track and manage the peaks of the audio signal. The plugin also includes both a full-band clipper that processes the entire spectrum and a multi-band clipper, allowing you to independently clip low, high, or both frequency bands. This provides the flexibility to maintain transparent processing or experiment with creative adjustments, depending on your needs. Built with simplicity and flexibility in mind, FAC Clipper is quick, lightweight, and highly intuitive. The clean, streamlined interface lets you focus on what matters most; controlling the peak levels to maximize loudness while preserving clarity and avoiding the pumping effects often associated with heavily limited signals. Thanks to its precise waveform and level meters, using FAC Clipper is a breeze. Simply add the plugin to your track and adjust the input gain until the waveform meter reaches 0 dB. This gives you a clear view of the signal's dynamic range, making it easier to identify peaks. Next, set the ceiling just below the peaks you wish to control. You can also adjust the Knee parameter for smoother clipping and fine-tune the saturation to achieve the perfect warmth and character. Use the Mix parameter to blend the clipped signal with the original audio, allowing you to control the amount of clipping applied. This helps preserve the natural character of the sound while enhancing loudness and harmonic warmth. This is an AUv3 Effect and requires a compatible host to work The documentation is available at fredantoncorvest.com/FAC_Clipper.html
