For most plugin-standards it is useless. Variable I/O is not filtered,
and many plugins also come in mono-compatible stereo-variant.
The MIDI filter never worked reliably either.
This is incomplete, pending backporting of Mixbus mixer_ui.h changes,
but this way it won't be forgotten.
And it might be handy to also include the shadow in Ardour's theme?!
When a non-existent file-path is given, GTK falls back to show the
containing folder and automatically goes up to parent folders until
the root.
This removes the explicit file/folder check and delegates the
behavior to GTK, allowing to set a folder for a non-existent file.
This fixes an issue with the session being marked as dirty without
any actual change. Also this method indirectly called during session-load
when the UI state is restored, a potential race with "Session::Loading"
being unset.
We no longer assume that Snap always uses the visible ruler lines.
If you want to snap to the grid, and ignore the users zoom scale, use SnapPref::SnapToGrid_Unscaled
This fixes 2 (known) oversights: "snap region(s) to grid" and "regions whose start are left of the canvas edge".
Some MIDNAM files use Patch-Banks that do *not* have a common midi bank
(CC0, CC32) but the Patchbank is instead just a collection of patches.
There may be more than 127 patches in a patch-bank and each of those
may be in a different midi-bank (e.g. Roland SC-88 Pro).
Midnams like these are now properly supported via dropdowns (in the
patch add/modify dialog and timeline), but ignored by the grid
(patch-widget). More work is needed.
This fixes an issue with pitch-shift using the most recently used
time-stretch algorithm, which may be "resample.." (effective NO-OP).
Also leave a ToDo note regarding rubberband crispness levels for later.
Leave the user in control while the slider is being dragged.
Previously there was a feedback loop:
User-drags slider -> value changes -> value is rounded
-> slider is updated with rounded value (while the user still drags)
