The Control and ControlList uses the raw value (eg. coefficient for gain,
Hz for frequencies) and those Lists are stored in existing sessions.
In the vast majority of cases interpolating automation values using exp/log
scale for dB, freq makes more sense -- it's also what the fader does.
Adding additional interpolation methods is future proof (we might at allow
to even add different methods per automation point (to the next) like other
DAWs do.
Currently it's mainly used in preparation for consistent GUI automation-
lanes. Between 2 points there's always a visual straight line.
Note the old Note::operator= was unsafe, since it made shallow copies of the on
and off events, which results in a double delete of events when the notes are
destructed.

Due to the failed try-lock.. AMP::_apply_gain_automation
is false. and Amp::run() uses a different gain factor.

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.
they are now done with region fades, rather than separate objects.
After this commit, Ardour will try to convert your session files
to the new crossfade format, but will make a backup in your
session folder first.
If you have works in progress using Ardour 3 it is
***STRONGLY RECOMMENDED*** that you back up session files before
updating to this commit.

Vimmers, try let c_space_errors = 1 in your .vimrc to highlight this kind of stuff in red. I don't know the emacs equivalent...

Anything related to the storage of events/values over a range of time lives in evoral.
This includes MidiModel (Evoral::Sequence) and automation data (AutomationList (Evoral::ControlList),
Automatable (Evoral::ControlSet), etc).
