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.
