Third party apps with Audio Unit (AU) functionality can act as instrument or effect plug-ins that integrate directly into the Cubasis workflow. As with StudioEQ or a Micro Sonic instrument for instance you can find them in the instrument browser and the effects menu under the Audio Units category.
- Instrument
-
Open the Instrument Browser by either tapping the instrument icon on your MIDI track or in the Inspector. Find the Audio Units category (only visible when you have at least one Audio Unit instrument installed) and select an app.
- Multi-output instrument
-
Some Audio Unit instruments feature more than one audio output. This is useful for distributing drum samples or instrument layers over multiple tracks, in order to mix them differently (volume, pan, effects…). Selecting a multi-output AU instrument routes its first output to the “main” track that holds the AU. Tracks that refer to the same AU (but to different outputs of this AU) are indicated by a double icon, a line pattern background, and they have the same color as the main track. There are three easy ways to add tracks for the other outputs, which are linked to the “main” AU track and don’t use any additional resources:
-
Open the Inspector’s Instrument panel and tap the Add x Tracks button, which displays the number of tracks that will be added in order to have one track per output. Note that the Inspector’s Instrument panel will only expand if an AU instrument that features multiple outputs is selected.
-
Or simply tap the Add MIDI Track button to add a track for the next instrument output.
-
Or manually create a new track, go to the Audio Units folder, tap the Multi-out Instances folder and select the AU instrument from the list of already loaded multi-output AU instruments in the project.

- Effect
-
Open the track Inspector. In Insert Effects or Send Effects find the Audio Units category (only visible when you have at least one Audio Unit effect installed) and select an app.
- MIDI Effect
-
Audio Unit plug-ins can function as MIDI effects, to be used for instance as arpeggiators or step sequencers. Find out how to use them in the MIDI Effects chapter.
