( THIS IS AN AUDIOUNIT. AudioUnits are app extensions, requiring any audio host application to perform. ) Use the same AudioUnits across all modern Apple devices, including the iPhone and the Mac (Apple Silicon). Native MacOS apps like GarageBand, MainStage 3 and Logic Pro X are fully supported. Any 3rd-party AUv3 supporting host should be able to host the plugin too. The JAX ESSENTIAL SERIES Phaser is a multi stage phaser modulation effect that uses multiple allpass filters, to produce all kinds of the famous phaser effect. A low frequency oscillator modulates depth and speed of the filter modulation on both stereo channels for various living and moving sound nuances. Make static sounding voices more interesting or create sweaping special effects. You may share the presets for this effect across all your supported devices. Around 200 factory presets are included, you can make and export/import your own. The complete manual is included and can be previewed on our support website: https://audio.digitster.com For advanced usage (i.e. mastering and exciting), we recommend to select the phaser from our SELECTIVE RANGE SERIES, which allows to limit the frequency range for processing. This build is truly 'universal', meaning, the audio unit is available for: - iOS (all actual iPhones) - iPadOS (all actual iPads) - macOS (Apple Silicon) - visionOS (Apple Vision Pro) Requirements: MacOS 11.0++ iOS 14.0++ Behaviour on all devices is identical. The parametric interface is resizeble and adopts to any screen size and orientation. This especially applies to Logic Pro X and all hosts with adjustable window sizes on all platforms. Display contrast can be adjusted freely and is now saved with each preset.

Introducing ChaosArp, the next-level MIDI arpeggiator/step sequencer designed to transform your musical ideas into intricate, dynamic patterns with a unique twist. ChaosArp is not just any arpeggiator; it's a powerhouse tool that uses the same advanced algorithms as LoAdKer to modulate pitch, rhythm, velocity, and duration, creating evolving, complex but high musical patterns that breathe life into your music. Dive into the heart of your creativity with ChaosArp's innovative ‘rhythm event’ feature, which allows you to explore a variety of rhythmic modifications. From repeaters to stretchers and rests for extra space and emphasis—ChaosArp has it all. Each one of these rhythm events can be assigned to any of the 6 available slots, offering limitless possibilities. Fine-tune your sonic exploration with the innovative ‘variance’ control - which goes one step beyond the simple ‘probability’ control that most arpeggiators have. Adjusting this setting for either pitch or rhythm (or both) will vary the character of the generated sequences, from fairly minimalistic to completely chaotic, thus opening up a world of endless variations. Elevate your music production today with ChaosArp and unleash patterns that inspire! Features: - Two modes: arpeggiator and stepper - 1-16 steps - Scale quantizer, never miss a note again! - Variable rate, from 1/128 to 4 beats - 3 arpeggiator modes (up, down, up/down) - 3 stepper modes (forward, backward, ping-pong) - 1 to 4 octaves range - Latch mode - Pitch randomizer with probability and variance control and random octave - Rhythm event selector with probability and variance control - 6 assignable rhythm event slots - 13 rhythm event algorithms, including repeaters, stretchers, and rests - Repeat, stretch, and repeat rest probability controls for further customization of the rhythm event algorithms - Randomizable velocity and duration with variable range - 4 performance buttons that temporarily override the probabilities of pitch, rhythm, velocity, and duration - Automatable parameters
