MidiPort::cycle_end() was never called, hence after the
first cycle all midi buffers were assumed to be
“mixed down” already.
this fixes
Midi-track 1 -[midi]-> Midi-track2 synth -[audio]-> out
on export.
Ardour calls input_streams(), output_streams() to determine
if the plugin is about to be re-configured (old stream I/O count
!= new I/O count) and emit PluginIoReConfigure() if that’s true.
If the plugin has not been initialized (no format set), we can
safely assume that it will need to be reconfigured.
Forcing Audio=Midi=0 will do so.
The only time where the format is not yet set and hence the actual
channel count is still unknown) is during the first call to
PluginInsert::configure_io().
At the time of writing, this all is a NOOP anyway! The only user
of the PluginIoReConfigure() signal is the GUI to update connection
lines… and since the first PluginInsert::configure_io() happens
during insertion before the plugin is painted and subscribed to
PluginIoReConfigure(), this function could return any value.
Still 0,0 is just more appropriate than assuming mono audio in/out
and no midi.
It is less likely that these would cause issues because the
variables involved define the size of the data read, which
is almost certainly less than the 32 bit limit (i.e. they are
not positional). But to keep things clean and to keep questions
at bay, make them 64 bit values.
Best to just do this as early as possible to avoid having to deal with this
situation all over the code.
Also fixes violation of LV2 MIDI specification, which requires no such events
are delivered to plugins.
Silly to make a junk Note just to pass to append_note_off_unlocked, which just
uses the fields that are on the MIDIEvent anyway then throws it away.
Also explicitly dispatch to append_note_off_unlocked in the caller for note ons
with velocity 0 rather than make append_note_on_unlocked deal with it.
Session::unset_play_loop() needed to be a no-op if play loop was
already false, and this was exacerbated now that it potentially
schedules butler transport work.
Try to make sure that we appropriately reset and refill track
buffers whenever we enter/leave loop playback,and whenever
we locate. In addition, if we start playing somewhere other
than the loop range while loop is enabled, then the first
time we hit the loop end, set up the track buffers.

Those objects do not have a versioned API by themselves.
This fixes issues with duplicate deployment (OSX, Linux bundles: cp) and
ardour listing control-surfaces multiple times (file index plugin dir).
Add a test, based on the worked example in www.korf.co.uk/spline.pdf, for
the constrained cubic spline interpolation.
The delta values for the float comparisons are rather arbitrary, I'm sorry
to say: they're basically chosen so that everything passes.
Gtk coalesces multiple exposes into a single combined rect.
If _single_exposure is disabled, we break apart the individual expose rects for the canvas rendering.
undo (n) where n > 1
redo (m) where m < n
new transaction.
Previously the redo list was left untouched.
This would lead to utter nonsense in the redo list.
AFAICT this never worked.
clear_events() must run in realtime context, which is likely to be asynchronous
with respect to the thread that calls it. So allow caller to pass in a functor
that will be executed (also in realtime context) after the clear is done.
Additionally, allow for a cross-thread callback to the event loop/thread which
initiated/allocated the clear event request so that it can flush its own pending
loop. This part probably isn't necessary but doesn't hurt and is a useful model.
The event would be placed back in the free list at the next event allocation
by the calling thread anyway.
Expanded API splits apart some CrossThreadPool functionality, and provides
access to current pool status information (available(), total(), used(), pending_size())
The region is the un-coalesced set of rectangles that were requested for redraw. The area
is the coalesced single rectangle. In the worst cases, the coalesced rectangle could span
the entire window even though just two pixels in opposite corners were to be redrawn.
There is a problem with the verbose cursor as it is dragged across MIDI tracks. TO BE
FIXED.
The infinite loop would happen if the 2 supplied paths were on different Windows drives - for example if one was on drive C:\ and the other on drive E:\
I don't think this new test will be detrimental to the other platforms but if it is, we could easily separate it out with a '#ifdef PLATFORM_WINDOWS' directive.
This gets us around a problem when converting a session from the old (Ardour2) format - where the Session Range (start) value was getting incorrectly set if we hadn't already set the end value.
at the time the graph gets around to takes down
client threads, the jack-backend’s jack_client has been reset.
But never mind: libjack does not care about it, anyway.
