The Track itself caches the Samples after each processing step which
allows it to be queried without the need to process it every time.
This result is queried by the WaveWidget which then caches the result to
prevent unnecessary heap allocations every paint event.
This makes Piano exactly as usable as when I started the large refactor
some years ago, which *sounds* like I'm a terrible person but now it (1)
looks nicer and (2) has a flexible backend that can already deal with
aribtrary kinds of processors on any track.
This is not related to the track controls and it may move into another
separate widget in the future. The move also allows to simplify the
octave slider callback logic.
This more generic name will better reflect the purpose of the widget in
the future, as this commit begins the long process of enhancing the
widget into a container for all controls of Piano's currently selected
track.
This makes Action shortcuts work again. :^)
`note_key_action()` and `special_key_action()` now return whether they
consumed the event. We don't even call them if any modifier keys were
held down, so things like `Ctrl+T` no longer play notes.
This is not the most useful keyboard binding anyways, plus it will be
extremely hacky to implement it with the generic processor parameter
widgets. Therefore, we'll get rid of it and add back a more generic
keyboard binding system later.
Each of these strings would previously rely on StringView's char const*
constructor overload, which would call __builtin_strlen on the string.
Since we now have operator ""sv, we can replace these with much simpler
versions. This opens the door to being able to remove
StringView(char const*).
No functional changes.
The only major functional change is that the Track now needs to know
whether it's active or not, in order to listen to the keyboard (or not).
There are some bugs exposed/created by this, mainly:
* KeysWidget sometimes shows phantom notes. Those do not actually exist
as far as debugging has revealed and do not play in the synth.
* The keyboard can lock up Piano when rapidly pressing keys. This
appears to be a HashMap bug; I invested significant time in bugfixing
but got nowhere.
Adds the ability to add a track and cycle through the
tracks from player widget. Also displays the current track
being played or edited in a dropdown that allows
for quick track selection.
Almost all synthesizer code in Piano is removed in favor of the LibDSP
reimplementation.
This causes some issues that mainly have to do with the way Piano
currently handles talking to LibDSP. Additionally, the sampler is gone
for now and will be reintroduced with future work.
This is the first step in transitioning Piano to a full LibDSP backend.
For now, the delay effect is replaced with a (mostly identical)
implementation in LibDSP.
The new ProcessorParameterSlider attaches to a LibDSP::Processor's
range parameter (LibDSP::ProcessorRangeParameter) and changes it
automatically. It also has the ability to update an external GUI::Label.
This is used for the three delay parameters and it will become useful
for auto-generating UI for Processors.
This allows for typing [8] instead of [8, 8, 8, 8] to specify the same
margin on all edges, for example. The constructors follow CSS' style of
specifying margins. The added constructors are:
- Margins(int all): Sets the same margin on all edges.
- Margins(int vertical, int horizontal): Sets the first argument to top
and bottom margins, and the second argument to left and right margins.
- Margins(int top, int vertical, int bottom): Sets the first argument to
the top margin, the second argument to the left and right margins,
and the third argument to the bottom margin.
This changes (context) menus across the system to conform to titlecase
capitalization and to not underline the same character twice (for
accessing actions with Alt).
