Be rude. Be rough. Be bold. Be tough! Arctic Pro Synthesizer / Vocoder is a modern subtractive synthesizer. It does not aim to accurately model or re-create vintage synths of yesteryear. Instead Arctic Pro offers the contemporary synthesist a rude, rough, bold and tough palette of sound to get stuck into. Including two massively fat HyperOscillators, dual filters, and easy to re-order master effects. While the Vocoder, used in conjunction with a suitable microphone, adds an extra dimension to your musical performance. HyperOscillators =========== Combine two HyperOscillators and one Sub Oscillator for some seriously fat sounds. Layer up to 8 oscillators in unison to create very thick and powerful tones. Spread detune and Mix these separate oscillators in real-time. More than just a "SuperSaw" - it's also a Super-square and Super-triangle. Powerful Presets =========== Legendary sound designer John ‘Skippy’ Lehmkuhl has exclusively designed the factory presets. John has worked as a professional sound designer since 1988 for Korg - making patches, combinations, drum kits as well as creating the sample data for almost every synth Korg has released since the M1. If you have owned one of these historic synthesizers you have heard John's presets. Sharing ===== Arctic Pro includes everything you need to record and share your audio and MIDI with others. Live record to WAV and MIDI files. Use AudioCopy, open audio directly in apps, or share with Kymatica AudioShare. Presets and Banks can be emailed and transferred via Wi-Fi and iTunes Files Sharing. And of course we also support Audiobus.

P422 Fairuz is a four-band op-amp parametric EQ that moves past hardware — the punch and harmonic density of classic op-amp circuits, with capabilities the originals never had. Shape your sound with HIGH, HI-MID, LO-MID and LOW bands, each with three selectable curves (Bell, Contour, Contour X2) and proportional Q: wide stays wide, narrow finds itself. LO and HI shelves with complementary dip behavior, switchable HPF/LPF, and the TREMOR circuit laying a sub-bass foundation below 30 Hz. Character comes from the circuit, not just the curve: the VOICE input transformer control and HAMMER output stage add body, density and saturation — op-amp color available even with the EQ bands off. Blend it all in parallel with the MIX control, no DAW routing needed. FEATURES - Four op-amp EQ bands with Bell / Contour / Contour X2 shapes - Proportional Q — musical at any width - Stepped or continuous frequency modes - LO / HI shelves with complementary dip - TREMOR sub-bass circuit below 30 Hz - Switchable HPF / LPF with position options - VOICE input transformer and HAMMER output stage saturation - MIX parallel blend and Dual Mono L/R behavior - Real-time IN/OUT spectrum analyzer with zoom - A/B states and 275+ factory presets with favorites - Out & Trim linked gain staging - Zero latency, optional oversampling FORMATS - AUv3 plug-in for AUM, Logic Pro, GarageBand, Cubasis and other AUv3 hosts - Standalone app with mic/interface input Bring console-grade op-amp tone to your iPad and iPhone.
