Audiobus 3.1 is now available. The update adds new features for working with Audio Units and audio hardware.

The free update makes it possible to use compatible Audio Units as MIDI sources and processors. Audio Unit sequencers, arpeggiators, chord filters, quantizers, modulators and other MIDI tools can now be integrated into Audiobus workflows. And support for full-screen Audio Unit views and factory presets makes it easier to work with Audio Units on iOS.

The update also adds the ability to route the individual outputs of apps and Audio Units to multi-channel audio hardware, or send audio to the built-in headphone socket and USB audio hardware simultaneously.

The update also adds Bluetooth MIDI device support for wireless workflows.

Here’s what’s new in Audiobus 3.1:

• Audio Unit MIDI out and MIDI effects. Now Audio Units can be put in the MIDI Input and Effect positions.
• Support for full-screen Audio Unit views. Supporting Audio Units now open in full-screen. A new expand/contract view button toggles the keyboard and view mode.
• Support for Audio Unit factory presets, with a new selector above the keyboard.
• Multi-channel output support: Send different audio streams to different output channels. And with Multiroute Audio enabled in Settings, send separate audio to the headphones and a plugged-in USB audio interface.
• Bluetooth MIDI support.
• Effect reordering via drag-and-drop.
• Inter-App Audio transport synchronization.
• UI design overhaul.
• iOS 9 support.
• CPU utilization indicator.
