2017-07-16Consistent Automation evaluation:Robin Gareus
Rule #89: The *owner* of each automation-control is responsible to evaluate automation of automated automation-controls (and emit Changed() signals to notify the GUI and slaved controls). This can happen during run(), when the Processor evaluates automation (eg. PluginInsert does that), but needs to regardless, every cycle. Emit Changed signal for GainControl This follow the same concept as PluginInsert: The Changed signal is called on demand when evaluating automation.
2017-07-04Fix session-event queue (multiple writer, single reader)Robin Gareus
The reading is done in rt-process thread, but multiple UIs (surfaces, GUI) can produce events to be queued.
2017-04-30Fix vari-speed and non-locked slave modesRobin Gareus
A transport-speed-change is no reason to skip processing. Prior to this change cannot_process() silently skipped in the process cycle of the speed-change (which may have been every process-cycle), without moving the transport or doing any processing.
2017-01-19Rework preroll-rec API:Robin Gareus
* rename: indicate that recording happens after preroll, punch-in * move API into libardour: rec+roll (no separate setup, seek, roll APIs)

2015-04-29delegate signal emission to dedicated thread.Robin Gareus
This works around abysmal performance (~.15ms) of boost::function and boost::bind (in PBD::Signal). The overall load is probably higher but the realtime thread remains unaffected.

2015-04-24send LTC during process_with_events()Robin Gareus
fixes #6277 This indicates a deeper problem though. Even removing a punch-range never clears out the events. and ession::process_with_events() does not use process_without_events() until re-start.

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)

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.
