Pulls out the last object from that list and attempts to establish a connection using AudioComponentInstanceNew().Refreshes a list of interapp audio compatible apps who are of type kAudioUnitType_RemoteGenerator or kAudioUnitType_RemoteInstrument (I'm not interested in effects apps).Sets up and activates an audio session with the correct session category.
I have written the code inside my HOST app that does the following sequentially: I want that sound to be routed into my host app and for my host app to be able to directly access the audio packet data as a stream of raw audio data. What I want to achieve is to establish a connection to an external node app who can generate sound. I am using the Audio Components Services and Audio Unit Component Services C frameworks to achieve this. Likewise, when loading a BeatMaker session that uses external apps, make sure you recall their previous configuration manually.I am writing an HOST app that uses Core Audio's new iOS 7 Inter App Audio technology to pull audio from a single NODE "generator" app and route it into my host app. When saving your BeatMaker session, you also need to save within external apps any configuration/preset you’ve made. However, IAA and Audiobus apps manage their configuration on their own. Important note on saving plugins and external apps presets:Īudio Units parameters and presets are automatically saved within BeatMaker sessions and banks. You can also manually configure the MIDI connection to IAA and Audiobus applications by pressing the “MIDI SETUP” located on the Plugin page and keyboard-split view.įor more information on using MIDI Audio Units plugins, please refer to this article.įor imore nformation on how to record from a plugin or external app, please follow this article. To open an IAA/Audiobus app screen from BeatMaker, tap on its icon located above the virtual keyboard.
If the plugin supports MIDI input, you can now control it using BeatMaker’s virtual keyboard or Performance view.Īudio Units plugins share their screen with BeatMaker, whereas IAA and AudioBus work as any other iOS applications. Once the plugin or app is loaded, tap anywhere in the PLUGIN view to open the Plugin Control View:Īudio and MIDI connections are now made between BeatMaker and your plugin. Tap on the “Load” button next to any plugin or app to load it.
Select which type of plugin or app you want to load: the menu is then automatically filled with compatible installed plugins and apps on your device. Tip: alternatively, you can also load a plugin from the Browser ’s “PLUGINS” page by drag & dropping it onto a pad within the Performance view. To load a plugin or an app, go to the Editor view, select a pad and press the PLUGIN tab at the top-right corner of the editor. Each pad can control an Audio Units plugin, or an external iOS app which supports Inter-App Audio or Audiobus protocols.
