A game could start and stop a song, but not steer one while it plays.
The battle theme could not take over on the next bar, a song could not
jump to a marker, and a track could not fall away when the player
hides. This is stage 3 of 5 in #338.
- Quantize: now, next beat, next bar (the default) or next marker. The
spot is the next one as the song is heard, and the change is planned
on the audio clock to the sample, round the loop as the ruler counts.
- Set song track turns one track in dB on top of the song's level, over
a fade, on the bus input before its FX and sends.
- Switch song plays another song, or the same one from a marker, in
place of the playing one. It keeps the playback number, so Stop song,
Set song track and On beat go on reaching it.
- A playing now has a key for its buses apart from its public number.
During a switch the old and the new song each have buses of their own.
- Play song has a "live tracks" switch. With it off a baked song plays
its bake, and Set song track on it writes a line to the log.
- A Switch song to a marker plays the notes, as a bake only plays from
its start.
Found on the way:
- A cut on a bar line faded over seconds in Chrome. cancelAndHoldAtTime
holds nothing where nothing is planned later, so the ramp ran from the
bus's last change. The turn now sets its start value on the spot. It
had been measured at 0.52 of full level 0.2 s past the bar line.
Tests:
- Unit: 23 new cases in beats, song-play, sound-library and the node
catalog. Counter-checks: 17 bends, all compile, all red.
- e2e 65 (atx): ALL PASSED, 73 checks. 65k3 is new. The switch landed
three bars after the start under the same number, and the track cut
on the next bar line with nothing in between. With the old ramp 65k3
is red (0.53 and 0.51 between).
- Gate (atx): CHECK EXIT 0, 334 files, 5144 tests.
