2012-11-17Sent precise transport information to LV2 plugins via events.David Robillard
We send the full transport state (frame position, BBT time, transport speed, meter) to the plugin: * At the start of a cycle whenever a relocate or transport speed change has occurred * On every occurrence of a meter change within a cycle This means the plugin gets a sample accurate meter/tempo map, even if the meter changes in the middle of a cycle. However, this is not quite right yet: things can get wonky if the tempo map is edited while rolling, since this code will not detect the change and fail to update the plugin at the start of the cycle. Other changes: * Factor out TempoMetric::set_metric() and simplify some tempo functions * Clean up LV2 URID stuff git-svn-id: svn://localhost/ardour2/branches/3.0@13513 d708f5d6-7413-0410-9779-e7cbd77b26cf

2012-01-02intermediate commit as all tempo/meter stuff starts to walk the precompute ↵Paul Davis
Bars|Beats list. Still have ::round_to_beat_subdivision() to fix. haven't really done any thorough testing at this point, but basic stuff seems OK git-svn-id: svn://localhost/ardour2/branches/3.0@11131 d708f5d6-7413-0410-9779-e7cbd77b26cf
2012-01-02new approach to tempo/meter: compute and store the entire map (every ↵Paul Davis
bar|beat point), thus enabling us to use the same computation to set the BBT points AND the metric markers (tempo + meter) on the audio timeline. It is known that snapping to the BBT grid doesn't work correctly right now, but this probably caused by the separate code in TempoMap::round_to_type() and i'll dig into that tomorrow. Note that the Bar|beat point list is evaluated "lazily" - we'll never store more than anyone actually needs to display or know, other than 1 minute's worth starting from frame zero git-svn-id: svn://localhost/ardour2/branches/3.0@11129 d708f5d6-7413-0410-9779-e7cbd77b26cf

2011-12-13more fun and games with meter and the tempo map: rename ↵Paul Davis
Meter::beats_per_bar() to Meter::divisions_per_bar() so that its clear(er) on what it is actually returning; use Meter::divisions_per_bar() in more (all?) places that need it; fix up dragging meter marks by removing the relevant meter section from the map while we drag; operator<< for some tempo-related objects git-svn-id: svn://localhost/ardour2/branches/3.0@10995 d708f5d6-7413-0410-9779-e7cbd77b26cf
2011-12-12fundamentally alter how we compute frames_per_beat(). this follows much ↵Paul Davis
discussion on IRC. fundamentally, tempo and ONLY tempo affects the computation of frames_per_beat(), meter has no effect at all. However, following typical DAW conventions, we continue to want the "grid" to show metric divisions, not fixed beats, so add a new method (Meter::frames_per_division()) that retains the old math which takes meter into account. This commit will alter the behaviour of MIDI notes in any session with multiple time signatures. They will likely break. Unfortunately, there is no alternative to this breakage at this time. git-svn-id: svn://localhost/ardour2/branches/3.0@10988 d708f5d6-7413-0410-9779-e7cbd77b26cf
