Detailed Description

Bind a UI control to emit MIDI through a pulp::midi::MidiControlBus.

bind_midi_cc(knob, bus, channel, cc) makes the control send a MIDI Control Change as the user moves it; bind_midi_note(button, …) plays a note while a toggle is on. The plugin's processor drains the bus into its MIDI-out buffer each block, so the moves land in the host's MIDI lane. This complements bind_parameter (which drives plugin parameters); a control can do either, or — by binding both — both.

One-way (UI → MIDI). UI-thread only.
