AUv3Controls
SwiftUI knob and toggle controls for use with AUv3 components. Uses the excellent Composable Architecture for Swift by Point-Free.
The controls are attached to AUParameter entities, so changes in the control will affect their associated AUParameter value. This works the other way as well: external changes to the AUParameter — say from a MIDI controller or preset load — will be reflected in the control.
