A thruster you can hear, and a latch on arriving and leaving

Browse Source 
Three patches, and the last of the sounds that were asked for.

The thruster bangs when it lights and rumbles while it burns. The rumble
is this game's first HELD note: its gate goes down when a thruster lights
and does not come up until every one is out. Only the edges matter - a
rumble restruck every frame would never get past its own attack, and a
bang struck every frame is a buzz - and the condition is the flames':
a held button with a dry tank is a pilot doing nothing.

Arriving latches two notes quickly. Middle C then the C above for taking
hold of the station, the same pair reversed for letting go, and two
octaves lower for the ground - the same shape in a different register,
because setting down and taking hold are the same kind of event. The
second note is PENDING rather than played: at an undocking the pilot is
mid-burn, and stopping the world for an eighth of a second to fit a note
in would be felt as the controls sticking. Where the game is stopping
anyway, runPend simply pumps it out.

Four channels for five sounds. The bang and the latch share one, because
a lander arriving either arrives or does not, and a crash ends the run.
That leaves the thruster its two, which it needs: a held note struck on
the same channel as the ignition bang would cut the bang off at the
moment it was meant to be heard.

---- A held note outlives the loop that was holding it ----

Landing while the thruster was still down ended the flying and then
waited to be told the message had been read, so the frame that would have
noticed the button coming up never ran. The engine roared under the
verdict and went on roaring until the machine stopped. Anything that
stops to wait hushes it now, and forgets last frame with it, so a thruster
still held when the waiting ends counts as lighting again.

---- Three checks that had to be rebuilt around the new noise ----

A landing is not silent any more, so the crash is measured against the
second BEFORE it rather than against a quiet landing. The dust samples
moved eight frames later, because the latch plays first. And the warning
check lost its measure twice: counting bursts could not tell a beep from
a nag, and measuring total length stopped working the day the thruster
got a rumble. It burns, stops, and listens AFTER - warned once there is
nothing left, nagging the last beep is still fading. Nought against 5,679.
