2014-11-14add abort() to non-reached codeRobin Gareus
This cleans up a lot of false-positives in static analysis and also helps compilers to optimize code paths in general. (tagging the fatal stingstream operator as ‘noreturn’ is far less trivial)

user pressed stopped (2) captured regions should end where the playhead ends

2014-04-17new transport option, "loop-is-mode" which optionally changes the role of ↵Paul Davis
the "play loop" button. If enabled, then the button simply changes the behaviour of the "play" button rather than actually starting playback. If disabled transport behaviour should be unchanged from before.
2014-01-16allow auditioning via the monitor section to work.Paul Davis
Ideally, we would feed the monitor section via an internal (aux) send/return, but this is an improvement over what we had before
2014-01-03don't split process cycle at endRobin Gareus
Keep in mind: While this is the correct thing to do, it hides another another bug under the hood, related to _global_port_buffer_offset in MidiPort::flush_buffers. For debugging the latter issue, revert this.
2013-12-02don't run MIDI clock "tick" if session is silent (e.g. due to a locate)Paul Davis
2013-08-13fixes to get MTC (and probably MIDI clock) slaving working againPaul Davis
incoming MIDI data has to be parsed EVERY process cycle, not just when Slave::speed_and_position() is called. The private MIDI::Parser owned by the MTC and MClck slaves was irrelevant, since the port has its own. See comments in midi_port.h on the strangled inheritance heirarchy.

commit fdbae82077db53add90df7448a06869dac89acc6 Author: Paul Davis <paul@linuxaudiosystems.com> Date: Wed Mar 27 21:45:28 2013 -0400 mammoth changes in basic signal flow, total redesign of MIDI channel filtering and more. commit 59343a8283698e02bc0f622313b29e98f449e4c8 Author: Paul Davis <paul@linuxaudiosystems.com> Date: Wed Mar 27 01:58:53 2013 -0400 initial working version after changes to MIDI channel filtering. may affect metering input too. testing not yet finished this commit merges many deep changes in ardour's internal architecture, combined with a total redesign of how MIDI channel filtering works. data in a track used to flow from JACK port buffers to diskstream's ringbuffers and was then copied from the ringbuffers into a BufferSet for use during Route::process_output_buffers(). The butler thread would handle the movement of data between the ringbuffers and disk. with this commit, data now flows from JACK port buffers into the BufferSet used for Route processing, and is copied from the BufferSet into the diskstream's ringbuffers (the butler thread continues to handle interactions with disk as usual). this change allowed a dramatic consolidation of code and simplification of most aspects of Track/Route::roll() and Track/Route::no_roll(). in particular, see Route::fill_buffers_with_input() which now concisely describes how we move data from JACK port buffers into the BufferSet for all Route types (including Tracks). this work was initially motivated by changing MIDI channel filtering so that we can process capture and playback independently. there is now a very clean pathway for this - see MidiTrack::roll() (NOTE: This needs implementing in the no-roll case too - a TODO item). the channel selector for MIDI tracks has been moved out of the track header and is now accessible via the context menu. more work is likely here, to make it (more) obvious to the user when filtering is going on.

2012-06-22introduce the idea of a "default transport speed", used whenever ↵Paul Davis
Session::start_transport() is called. Only the shuttle controller alters it, and even that only alters it in wheel mode, which means that stopping the transport does not rever the default speed back to zero. To get back to zero either switch the shuttle controller back to sprung mode, or change the speed back to zero (fixes #451 ... yes, really, a 3 digit bug fixed!) git-svn-id: svn://localhost/ardour2/branches/3.0@12819 d708f5d6-7413-0410-9779-e7cbd77b26cf

2012-05-24Remove over 500 unnecessary includes (including 54 of session.h).David Robillard
It's slightly possible that this causes trivial build failures on different configurations, but otherwise shouldn't cause any problems (i.e. no actual changes other than include/naming/namespace stuff). I deliberately avoided removing libardour-config.h since this can mysteriously break things, though a few of those do seem to be unnecessary. This commit only targets includes of ardour/*.h. There is also a very large number of unnecessary includes of stuff in gtk2_ardour; tackling that should also give a big improvement in build time when things are modified. git-svn-id: svn://localhost/ardour2/branches/3.0@12420 d708f5d6-7413-0410-9779-e7cbd77b26cf

they are now done with region fades, rather than separate objects.
