CombineMIDI

Swift package made for easy connection of MIDI controllers to SwiftUI (or UIKit) using Combine.

This package was created as a part of UIKonf 2020 talk Combine: Connect MIDI signals to SwiftUI. It's main goal is to read messages from all MIDI sources and to be able to present these values in the user interface.
