How do I use multi-out VST plug-ins?
Bitwig Studio supports multi-out VST plug-ins, and chains can be added dynamically. Add the plug-in to an instrument track and then click the double arrow icon in the top of the plug-in panel. You'll now see options to add multi-out chains.
Chains can be added manually or automatically. Once the chains are added they are accessible as individual channels in the Mixer Panel.
To access audio channels from a multichannel plug-in on a different track: either from a track's audio input chooser or from an Audio Receiver device's SOURCE menu, select the track of the multichannel plug-in, then select its Chains submenu, and finally select the desired audio source.
