- clearing automation points sets control to "off" rather than touch.
- multiple touches on the same pass acts consistently (no more
fader jumps on mouse button press
- use actual value for initial point rather than some arbitrary
default. clarify new semantics of add () (with_default->with_initial).
- clean some whitespace
- add guard points as needed in stop.
- catch grab broken signal (i can't trigger it, but the docs seem
to think it is essential).
- probably fixes a lot of cases where note ids are assumed to be
unique (they weren't for copies and some others).
- wrong branch, but it needs testing.
towards fixing #6238 and #6096.

Due to the failed try-lock.. AMP::_apply_gain_automation

Fixes bug #6166 (except record).
This attempts to follow the "current" control value somewhat aggressively:
* On locate, slider is set to the value from the top region at the new
transport position.
* Playback or MIDI input is followed "live".
* Whenever the slider is moved (including automatically), that value is emitted
as an immediate event to keep external gear in sync.
General idea is that the Ardour slider should act as a mirror of an external
hardware knob, and both should be synced to whatever the control is at the
current transport position. Since we lack real playback/touch/etc modes for
these for now, we must choose one behaviour, and this seems like the most
reasonable one.
Follow is handled in the audio thread, which is probably not ideal, but since
these controls have no lists and do not record, should be fine. Probably.
This avoids stuck notes if active notes are edited, but without stopping all
active notes in the region on any edit as before.
This implementation injects note ons in places that aren't actually note
starts. Depending on how percussive the instrument is, this may not be
desired. In the future, an option for this would be an improvement, but there
are other places where "start notes in the middle" is a reasonable option. I
think that should be handled universally if we're to do it at all, so not
considering it a part of this fix for now.
Best to just do this as early as possible to avoid having to deal with this
situation all over the code.
Also fixes violation of LV2 MIDI specification, which requires no such events
are delivered to plugins.
Silly to make a junk Note just to pass to append_note_off_unlocked, which just
uses the fields that are on the MIDIEvent anyway then throws it away.
Also explicitly dispatch to append_note_off_unlocked in the caller for note ons
with velocity 0 rather than make append_note_on_unlocked deal with it.
Add a test, based on the worked example in www.korf.co.uk/spline.pdf, for
the constrained cubic spline interpolation.
The delta values for the float comparisons are rather arbitrary, I'm sorry
to say: they're basically chosen so that everything passes.
When the crossfade length is only 1 frame, I got strange
gain coefficients from get_vector (63 in my case).
The function wrongly returned the x axis value.
We're still a very long way from tolerant of weird SMF files (libsmf takes a
"crash if input is not exactly perfect" philosophy, if we're going to be polite
and elevate such a thing to "philosophy"), but at least we'll get what's there
from files truncated by old broken versions of Ardour or other situations.
This was a very clever attempt to fix a non-problem. If the platform doesn't have enough file descriptors available
then the platform is broken and we're not going to hack around trying to fix it.
For things like copying from pitch bender to a CC.
Also things like fader to pan, but that seems a bit funny. The conversion
probably needs to be a bit smarter here, perhaps taking the normal into
consideration...
