I am trying to implement MIDI Out for an app. The app will generate a MIDI sequence that could be directed to be played on another app (synthesizer or as an input to apps like AUM). I noticed that certain functions in the CoreMIDI framework like MIDIReceived and MIDISend have been deprecated. I couldn't find any new functions that replace these. CoreMIDI documentation is very sparse and lacking. Anybody know of new functions that replace these?

They're focusing on the new MIDIEventList frob now.

Code Block 
@available(iOS 14.0, *)
public func MIDISendEventList(_ port: MIDIPortRef, _ dest: MIDIEndpointRef, _ evtlist: UnsafePointer<MIDIEventList>) -> OSStatus
@available(iOS 14.0, *)
public func MIDIReceivedEventList(_ src: MIDIEndpointRef, _ evtlist: UnsafePointer<MIDIEventList>) -> OSStatus

I believe that you have to ignore the "deprecated" annotations and use the information in https://bradleyross.github.io/ObjectiveC-Examples/Documentation/BRossTools/FunctionalArea.html. The project is in the BRossTools folder in the BradleyRoss/ObjectiveC-Examples GitHubrepository.
