This works around a bug in OnsetDetector.
It requests a buffer of 1114 samples but later FFT
bails out if the buffer size is not a power-of-two.
Also large buffersizes fail.
Work-around: use ADAPT_ALL_SAFE (no buffersize
adapter), use a reasonably small buffersize.
The current settings work, even though it produces
the following warnings (vamp-plugins/OnsetDetect.cpp)
WARNING: OnsetDetector::initialise: Possibly sub-optimal step size for this sample rate: 512 (wanted 557)
WARNING: OnsetDetector::initialise: Possibly sub-optimal block size for this sample rate: 1024 (wanted 1114)
This commit should be reverted once VAMP/QM/aubio
is updated/fixed.
Technically it doesn't make much difference but from what I can tell, the only files which #include 'gtk2_ardour/gui_thread.h' are the source files from gtk2_ardour itself. The support libraries always #include 'gtkmm2ext/gui_thread.h' directly (which seems sensible). So for consistency's sake, let's keep it the same for libcanvas.
This moves MIDI channel filtering into a reusable class and moves filtering to
the source, rather than modifying the buffer afterwards. This is necessary so
that the playlist trackers reflect the emitted notes (and thus are able to stop
them in situations like mute).
As a perk, this is also faster because events are just dropped on read, rather
than pushed into a buffer then later removed (which is very slow).
Really hammering on mute or solo still seems to produce stuck notes
occasionally (perhaps related to multiple-on warnings). I am not yet sure why,
but occasional beats always.
Add "PERFORMER" to the exported .toc & .cue files based on the value of the
"album_artist" metadata field, and also use the value of the "album" field
for the TITLE if is set, falling back to the session or range name if it is
blank.
During DnD, the region uses the 'old/current'
midi_stream_view()'s range and its position/height calculation.
Ideally DnD would decouple the midi_stream_view() for the
region(s) being dragged and set it to the target's range
(or in case of the drop-zone, FullRange).
but I don't see how this can be done without major rework.
For now, just prevent visual bleeding of events in case
the target-track is smaller.
Invalidate all source entries from the image cache when we get our
region's DropReferences signal, while ignoring any subsequent regions with
no source.
* Handle large (delta > 1) movements into the DZ
which are not due to invalid-drop positions, but
caused by laggy GUI or rapid user movements.
* ignore busses when moving out of the DZ.
Allow to drag multiple regions from different tracks
to/from the dropzone.
Busses & Automation-lanes are ignored, as are
hidden tracks.
Any region may serve as mouse drag anchor.
