Making CoreMIDI on iOS and macOS easier for developers and users

MidiBus is a freely available library for developers to add (or retrofit) well-behaved and robust CoreMIDI to their apps with just a modicum of effort.

Feature list

• Simple to add via Objective C class to iOS apps
• Sits on top of CoreMIDI, so compatible with CoreMIDI devices and other apps
• MIDI events are presented to apps as discrete, classified and validated messages
• Internally written in C with focus on performance
• Automatic setup of virtual ports for an app
• Automatic setup of 'well behaved' OMAC compliant MIDI app
• Ability to query the MIDI topology with interfaces being presented in matched pairs with cleaned up and unique (enumerated where necessary) names
• Large sysex (eg. bulk dump) support
• Built in support for OMAC app switching (including via MIDI command)
• Generate stable MIDI clock signal from your app
• Documented and supported down to iOS 4.3 including 32 and 64 bit architectures and for macOS down to 10.6 Snow Leopard 32 and 64 bit.
