Quick answers
Which DAWs does it work in?
Any DAW that hosts AU or VST3 plug-ins. It is developed and tested in Ableton Live on macOS.
Is the demo the real plug-in?
The demo runs the same signal processing as the plug-in, ported to run in your browser. The plug-in itself runs natively in your DAW.
Is there a trial version?
Not yet. Try the browser demo above.
My DAW does not show the plug-in
Rescan your plug-ins and restart the DAW. On macOS, the AU is in /Library/Audio/Plug-Ins/Components and the VST3 in /Library/Audio/Plug-Ins/VST3.
