* reserve "probe" to actually probe for devices
* use separate probe for libusb and MIDI port devices
* use "available" to check if surface can be used
* allow both methods to be NULL
* remove unused ControlProtocolDescriptor* argument
Most surface just return `true` for available.
This is better provided by Plugin::print_parameter, which
is called by PluginControl::get_user_string(). This removes
special cases for the mode enums.
This is mostly a simple lexical search+replace but the absence of operator< for
std::weak_ptr<T> leads to some complications, particularly with Evoral::Sequence
and ExportPortChannel.
This test seems to be compiling and passing just fine (when run in
isolation), so turning it back on seems like a good idea. To make it
pass when run as part of the full ardour test suite, this does remove
the WebSockets control surface from the control surfaces test though, as
that control surface messes up the event loop of the main thread, which
would otherwise cause use-after-free crashes in the session test.
This disables the feature added in 057fd9259e.
The idea was to use double-click to reset the fader (like
Harrison consoles). Simply re-select can lead to accidents.
Keep file-system paths and PBD::Searchpath mostly separate.
This amends 58c2b0a848 libs/fst directly includes relevant
ardour C++ code, so lib/fst must not link against libardour.
The problem was that 58c2b0a848 introduced additional
dependencies on other libardour functions.
libardourcp and now libardour_midisurface are not control
surfaces, but helper libraries for those.
They need to be deployed to the library folder (shared between
ctrl surfaces) and not scanned as ctrl surfaces at runtime.
DeviceInfo (bindings file) can include explicit motorized
and threshold settings. These values, when specified, are
used during load_bindings() during set_state and overwrote
any user customization.
Furthermore showing the GUI invalidated any prior setting
by explicitly calling binding_changed, which re-applies.
