2017-06-21Implement additional ControlList interpolation methods.Robin Gareus
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.
2017-06-21Remove separate ControlList min/max/default, use ParameterDescriptor.Robin Gareus
2017-06-03add const-ness: Evaluating a curve does not change it.Robin Gareus
Note that the ControlList's lock and cache are already mutable.
2016-12-04Remove dead/annoying/unsafe codeDavid Robillard
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.
2015-10-05NOOP, remove trailing tabs/whitespace.Robin Gareus
2015-04-15Replace control list locks with RWLocks4.0-rc4Robin Gareus
towards fixing #6238 and #6096. GUI thread: #2 Glib::Threads::Mutex::Lock::Lock #3 Evoral::ControlList::eval #4 Evoral::Control::get_double #5 ARDOUR::AutomationControl::get_value #6 ProcessorEntry::Control::control_changed .. #15 PBD::Timer::timeout_handler at the same time: Audio Thread (try-lock, fails) #0 Evoral::Curve::rt_safe_get_vector #1 ARDOUR::Amp::setup_gain_automation #2 ARDOUR::Route::process_output_buffers Due to the failed try-lock.. AMP::_apply_gain_automation is false. and Amp::run() uses a different gain factor. -> click.
2015-01-19Curve::_get_vector: fix return value when veclen == 1Guido Aulisi
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.

2012-04-16Fairly major change to the way in which crossfades are handled;Carl Hetherington
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. git-svn-id: svn://localhost/ardour2/branches/3.0@11986 d708f5d6-7413-0410-9779-e7cbd77b26cf

Anything related to the storage of events/values over a range of time lives in evoral.
