Check, in order, if the io is connected to another Ardour route, then a
user bundle, then some physical ports with simple configuration, and
lastly another client.
Before, Routes were considered connected as long as every io port
connected to that route, even if the channel order was mixed or worse if
all ports were connected to the same channel. Now Routes and Bundles are
considered connected if they are exclusively connected, in the right
order, to all their ports with matching datatype.
If a bundle was already connected, a click on the corresponding entry
disconnected it, essentially giving toggle semantics to the io menus.
This behavior has three problems:
— When clicking on a not yet connected bundle, the new bundle replaces
any already connected one. This is not consistent with a toggle mode.
— It is a less discoverable and less easy way to disconnect a bundle
than the already present "Disconnect" menu entry.
— Bundles that match the I/O channels only partially (recently added to cater
for e.g. MIDI+STEREO tracks connecting to Master) are never
considered "connected" because the channels are not connected 1:1.
Those will thus never toggle, making the behavior inconsistent.
Change the semantics to ensure a bundle is connected on click instead.
Ensure the master bus is the first proposed bundle if it is present.
Also propose internal route inputs before physical outs or other
software via JACK.
Last, but not least, add to the menu not only exactly matching bundles,
but also bundles that have the same number of channels than the route
output when considering only the DataType we think the user wants to
use. This covers both the case of a MIDI+STEREO instrument track
connecting to master, and the case of a STEREO track connecting to a
MIDI+STEREO vocoder track.
Avoid proposing the monitor section in the list if the current route is
not the master bus. Also allow the caller to pass a DataType as argument
to allow partial bundle match on that datatype only.
The heuristic currently used to display port connections in a
compact user-friendly way only considers Audio and MIDI data types.
Replace it by a better heuristic that does essentially the same thing
with all DataTypes, assuming they are ordered by likeliness of usage.
Currently the result is the same since there are only two DataTypes.
Trim automation is planned via SlavableAC as normal AutomationMode.
Some of this code have a revival (a special "Trim+Preview" state
before merging Automation but that has to be more general than Pan & Gain.
The numeric formatting is equivalent. Even though this string is being used in
the UI as a label I think this is another case where we don't want a localized
numeric string, which would only be relevant with a track count >=1000.
This reverts commit b3722f7063.
In some cases ardour shows context-menu on right-mouse-button
release. In this case selecting a menu-entry should happen
with the left-mouse button (or any button?!)
Using ev->button is only correct if the menu is temporary and only
visible while the button is held, button release then activates the
menu-item.
This needs further work, in some cases allowing any button (0) to work
makes sense and overall consistency needs to be improved.
Different places use different strategies for context-menus which
don't always match the button used in the event-handler.
This is a hotfix (to make TAV context menus work again with left-click)
The trim knob has been designed to operate only on audio channels. If
the bus has none, hide the knob that would otherwise have no effect at
all.
Factor the trim control show/hide code out of MixerStrip::set_route(),
and also call that code in response to I/O changes in the route.
In order to choose which port name to display (if any) in the button,
MixerStrip::update_io_button() first chose a primary type for the input
or output. It was AUDIO in all cases, except if the route was a
MidiTrack where the primary type was MIDI.
In the latter case, it enabled the following code of update_io_button()
to show the MIDI sources feeding the MidiTrack rather than showing an
unhelpful dash.
But this simple heuristic has several shortcommings:
- Going further, tracks and busses will probably loose strong types so
the approach is not future-proof;
- It doesn't take midi busses into account, yet there is no reason for
them to be handled differently than midi tracks;
- It falls short when the midi track contains a synthesiser and is
meant to output audio.
Improve the heuristics by choosing the data type as follows:
A) If there are connected audio ports, consider audio as primary type.
B) Else, if there are connected midi ports, consider midi as primary type.
C) If there are audio ports, consider audio as primary type.
D) Else, if there are midi ports, consider midi as primary type.
These new heuristics give the same results for audio tracks and busses
(whose audio inputs have not been removed), and the same result for the
input of midi tracks (again, provided the inputs have not been tampered
with). It improves the situation for inputs of midi busses, and output
of midi tracks and busses, especially when synthesisers are in use.
