Detailed Description

template<typename super_device_t, typename midi_pin_t, typename device_t = dx::test::midi::device<super_device_t>, typename driver_t = dx::proxy::driver<device_t>, typename super_driver_t = dx::test::driver<super_device_t, device_t, driver_t>>
class dx::test::midi::driver< super_device_t, midi_pin_t, device_t, driver_t, super_driver_t >

the MIDI exerciser: it sends over one port and counts what comes back on another - the round trip's losses, its slips and its latency, no audio ring involved

< the test driver it adds its command to: a bus's own (dx::test::usb::driver) keeps that bus's commands beside it

MIDI round trip test.

miditest(): test::MIDI::write: pin->write() -> coremidi::stream::transmit() -> OS MIDI -> coremidi::server::pin::receive() -> circular -> HW MIDI Ouptut port -> cable -> HW MIDI Input port -> coremidi::server::receive() -> OS MIDI -> coremidi::stream::receive() -> pin->read(): test::MIDI::read

the counter as a control change: its low 4 bits the channel, the next 7 the controller, the next 7 the value; byte holds whatever a ring's decode() hands out

< the control change's bytes: what goes out, what the ring carries of it
