2013-12-29use buffer APIs instead of raw memcpy, fix plugin bypassRobin Gareus
2013-12-28centralize buffer silent-flagRobin Gareus
fixes possible x-talk 1 in, >= 2 out tracks: Previously, only the first route-buffer of the input buffers were marked as non-silent in Route::process_output_buffers(). Other buffers in the set (e.g. post-panner) would contain audio but not marked as non-silent.
2013-08-02rework MIDI [processor|plugin] chainRobin Gareus
* forward midi-data around plugins that have no MIDI-out * allow to insert plugins with no MIDI-input at a point with one MIDI-channel This works because excess ports (both plugin and route) remain unconnected and use scratch-buffers. Tested with LV2, LXVST and LADSPA. (AU plugins with variable in/out retain the old behavior, no bypass) fixes http://tracker.ardour.org/view.php?id=5630
2013-08-01use zeroed scratch buffers for "silent" plugin runsRobin Gareus
Plugins rewrite the buffer data in-place and some plugins can produce output even when fed with silence. Hence, during a PluginInsert::silence() run a plugin can inject data into the "silent" buffers which causes side-effects. Kudos to Chris 'oofus' Goddard for finding this issue.

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

2011-11-01a better fix for the silent buffer issue: whenever we run a plugin, mark all ↵Paul Davis

2011-10-21More robust plugin I/O mapping.David Robillard
This does not change the actual mapping logic, but makes the application of the mapping much more robust. If there is no valid mapping for a given port, that port is connected to silence (instead of crashing messily and/or via a failed assertion). Also tolerate mappings that nonsensically map to a buffer that is not present (this particularly happens for MIDI ports in some cases) as a temporary fix. The mapping logic needs work and/or our concept of just how much MIDI we support in a route needs simplification... git-svn-id: svn://localhost/ardour2/branches/3.0@10262 d708f5d6-7413-0410-9779-e7cbd77b26cf

2011-04-03Implement LV2 files extension.David Robillard
This extension works with the persist extension to allow plugins to save references to files in their state, but still allow the host (e.g. Ardour) to control where files are located, making it possible to do a deep export of a session with all files (e.g. loaded sampler banks) included.
