Voice bot is a real time channel vocoder. A vocoder takes the spectral information of one sound also known as a modulator and uses it to shape another sound called a carrier. The resulting sound is a bit like a singing robot. Use the microphone to play live or record your own loops for playback, with a few different trigger modes using the keyboard. Further process the sound with a bit and sample crusher, delay and flanger. Play with the built in 25 key dynamic keyboard or using core MIDI with options for MPE. Run voice bot stand alone on iPad and iPhone or as a AUv3 plugin in your favourite host. Connections to other apps are also available through Audiobus and Inter Appp Audio. +++ Microphone input +++ Vocoder with up 128 filter bands +++ Polyphonic carrier source or Mono with glide settings +++ Built in 3 Oscillator carrier source, with saw, square and noise shapes +++ Record or import carrier sample loops +++ Freeze spectrum +++ Bit and sample rate crusher +++ Pitch tracking using Yin algorithm +++ 4 tap stereo delay +++ flanger +++ Multiple sample loop trigger modes +++ 25 key dynamic keyboard +++ Core Midi, Bluetooth Midi, Inter App Audio Midi and AUv3 MIDI +++ Midi CC available for all audio parameters +++ Limited MPE Midi support +++ Modulateble parameters: bands, bit crush, sample crush, delay feedback, flanger mix, vibrator and pitch bend

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.
