Detailed Description

template<typename backend_t>
class dxd::dmus::stream< backend_t >

dmus::stream: a DirectMusic pin stream over its device's MIDI ring

Capture: a thread woken by the ring's broadcast decodes the USB MIDI packets of this pin's cable into DirectMusic events. Render: the events are encoded into the ring, the bus's tick sends them.
