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.
