MIDIManagerSharp
A Swift MIDI manager.
Orginal by Gene de Lisa, give him some love for doing the original world. https://github.com/genedelisa/SwiftMIDI
I just set this up as a Swift Package, with some tweeks by me Stan Rosenbaum
The major change was that it adopted a true Delegate Pattern.
To use it in your own project, adopt and implement the MIDIManagerDelegate Protocol.
