This brings the builtin, LV2, and VAMP effects inline with the
Audio Units, LADSPA, and VST effects. All effects now share
a common UI.
This gives all effects (though not implemented for all):
User and factory preset capability
Preset import/export capability
Shared or private configuration options
Builtin effects can now be migrated to RTP, depending on algorithm.
LV2 effects now support graphical interfaces if the plugin supplies one.
Nyquist prompt enhanced to provide some features of the Nyquist Workbench.
It may not look like it, but this was a LOT of work, so trust me, there
WILL be problems and everything effect related should be suspect. Keep
a sharp eye (or two) open.
Solves the problem of what the "Settings" button should say
by converting it to a bitmap button.
Adds the missing "bypass effect" button.
The Ok/Cancel buttons are now Apply/Close buttons and the
dialog stays open after the apply is done.
Record is no longer disabled when an RTP effect is open as
the RTP effect now monitors when recording starts and disables
its buttons as needed.
Added "Play", "Skip forward", and "Skip backward" buttons.
While the other stuff is required, this last one is in to
get a feel for its usefulness. We'll need to get feedback
on it pretty quickly so we can rip it out if need be.
The big thing is the common efffects UI. Right now Ladspa and VST
have been converted to use it and Audiounits will be next. It makes
everything nice and consistent while reducing the clutter in the
dialog.
Other goodies are:
Ladspa effects now show output controls when supplied by the effect
Ladspa effects now work fine as Analyze type effects
Ladspa now has user presets
VST effects dialog is now less cluttered...leaving more room for the effect
Ladspa and VST effects now share a common UI
Ladspa and VST effects are now usable in chains
Ladspa and VST effects now handle user presets the same way
Currently active effects settings automatically saved and reloaded
Can now do numeric range checking on input fields.
And, as always, plenty of critter squashing.
I've made it where you can enable and disable via experimentals:
EXPERIMENTAL_REALTIME_EFFECTS
EXPERIMENTAL_EFFECTS_RACK
You will notice that, as of now, the only effects currently set up for
realtime are VSTs. Now that this is in, I will start converting the
rest.
As I start to convert the effects, the astute of you may notice that
they no longer directly access tracks or any "internal" Audacity
objects. This isolates the effects from changes in Audacity and makes
it much easier to add new ones.
Anyway, all 3 platforms can now display VST effects in graphical mode.
Yes, that means Linux too. There are quite a few VSTs for Linux if
you search for them.
The so-called "rack" definitely needs some discussion, work, and attention
from someone much better at graphics than me. I'm not really sure it should
stay in as-is. I'd originally planned for it to be simply a utility window
where you can store your (preconfigured) favorite effects. It should probably
revert back to that idea.
You may notice that this DOES include the API work I did. The realtime effects
were too tied to it and I didn't want to redo the whole thing. As I mentioned
elsewhere, the API stuff may or may not be very future proof.
So, let the critter complaints commence. I absolute KNOW there will be some.
(I know I'll be hearing from the Linux peeps pretty darn quickly. ;-))
Fixed some weird layout issues due to ShuttleGui misuse.
Fixed some SetName cut/paste errors (e.g., it used to say "To frequency in seconds" !).
Fixed rounding direction in PitchOctave() for negative MIDI notes.
Fixed a comment in ShuttleGui.cpp.
