Combine: Connect MIDI signals to SwiftUI
summary
Builds a small library that wraps Core MIDI and exposes a mini publisher for Combine so live MIDI control-change, note-on and XY/Z streams feed Swift state. Demo is a macOS SwiftUI app that maps knobs to gradients, a pad matrix, and an XY touch control, uses operators like scan, filter, zip/combineLatest, removes duplicates, and buffers 100 samples with a 60 Hz timer. All pieces are implemented and shown working in real time.
