Please refer to the product page of Cubasis for the up to date list of compatible hardware.


Additional information on Inter-App Audio, Audiobus and CoreMIDI routing can be found here.

Audio Units

Third party apps with Audio Unit (AU) functionality can act as instrument or effect plugins / addons that integrate directly into the Cubasis workflow. As with StudioEQ or a Microsonic instrument for instance you can find them in the instrument browser and the effects menu under the Audio Units category.

Audio Unit presets

Press the Presets button to the top left of the rack and a list of presets will open below. Tap a preset to load it and apply it to your audio unit effect. Instrument presets will be shown in the regular instrument browser.

Note: Presets are not visible in the MediaBay; deleted presets can be restored via the Files App, AirDrop or iTunes File Sharing.

Audio Unit automation

Like other instruments and effects, Audio Unit parameters can be automated. Press the green Read or red Write button in order to create or edit automation for the Audio Unit track. Find more information on automation here.

Inter-App Audio

Inter-App Audio (IAA) is a universal routing system for iOS, allowing you to route audio, MIDI and effects between Cubasis (host) and compatible node apps in realtime. There are three basic types of nodes:

To use an Effect node in Cubasis, follow these steps:

  1. Select the track you wish to add an effect to.
  2. Open the track Inspector and select the the Insert or Send effects panel.
  3. Tap one of the slots and choose Inter-App. A list of available effect apps will appear. Select one to assign it.
  4. Tapping the app icon in the effect slot will take you to the app. From here you will be able to customize the effect and control Cubasis remotely.

To use an Instrument app, follow these steps:

  1. Tap the instrument icon on your desired MIDI track.
  2. Open the instrument browser to the left and expand the category Inter-App. Select an instrument of your choice.
  3. Once the instrument app is connected to Cubasis, the icon lights up and you are able to play the instrument on your Cubasis keyboard like any other. Tapping the icon will take you to the app directly for customization of the sound. Note: Instrument node apps cannot send MIDI information to Cubasis via Inter-App. To record MIDI from another app, use CoreMIDI instead.

To use Audio input, do the following:

  1. Select an audio track.
  2. Open the Inspector and open the Routing panel.
  3. Tap Input source (Mono by default) choose Inter-App. A list of available apps will appear.
  4. After assigning an app, its icon and name will appear in the input slot. Tap the icon to switch to the app.
  5. From here you can remotely record the generator's audio into Cubasis. Some generator apps can also act as instruments; however, they may only be connected once. Note: Monitoring must be enabled on Inter-App audio tracks. Background Audio must be enabled for both apps.

Limitations of Inter-App Audio routing:


Audiobus is a signal transfer app, allowing you to route audio material as well as MIDI between Cubasis and other compatible apps in realtime.

Using Audiobus, you can

Having launched the Audiobus app, tap either the input or output port and choose Cubasis. You can add multiple apps to the input port.

When Audiobus is active, it provides an overlay interface for easy inter-app control. When Cubasis is in the background, it offers the following means of remote control:

Follow these steps to record audio from another app into Cubasis:

MIDI via Audiobus

To route MIDI signals via Audiobus, select the MIDI page after launching the Audiobus app, then follow the same instructions as above.

MIDI Hardware

Audiobus can potentially handle all MIDI routing, including MIDI hardware. Connected MIDI hardware will be listed alongside Audiobus compatible apps.

Note: While Audiobus MIDI can run parallel to CoreMIDI and Virtual MIDI, they cannot be used on the same track simultaneously.
