03In depth

Effect control and the ribbon slider

The main controls center on an amount knob that sets how much of the effect is added to the signal. Alongside it, a ribbon slider lets you move through the preset's settings in real time.

The slider includes a tempo-based slide-back option, so the parameter can return to its starting position in sync with your project tempo. This makes it a practical tool for rhythmic movement and performance changes.

MIDI control is available, so the ribbon and other parameters can be mapped to hardware or automated from your host.

Interface and visual feedback

The interface can be scaled to 100%, 125%, 150% or 200%, which helps on high-resolution or smaller displays. The graphics respond to audio and to the effect itself, giving a live view of what the plugin is doing to the signal.

With 50 presets included, you can start from a finished sound and adjust the amount and ribbon to fit your track.
