... I don't fully understand why this fixes it, but I could figure out what
was different between ESC and Cancel button which did not have the problem.
In addition, the Xcode project can now build against the 10.6
or 10.7 SDKs. All that is needed is to change the SDK version
and the other settings will change automatically.
... for functions in final classes.
override is like const -- it's not necessary, but it helps the compiler to
catch mistakes.
There may be some overriding functions not explicitly declared virtual and I did
not identify such cases, in which I might also add override.
... Should have no effect on generated code, except perhaps some slight faster
virtual function calls. Mostly useful as documentation of design intent.
Tried to mark every one of our classes that inherits from another, or is a
base for others, or has abstract virtual functions, and a few others besides.
As usual, I started out intending to do as little as possible
to this to get it working and wound up going overboard.
However, I believe it does allow easy management of the effects
and this will provide a basis for the full blown plugin manager
dialog.
Non-linear effects now process tracks before mixing.
This will be slower when multiple tracks are selected
but the preview should now match the applied effect.
SetLinearEffectFlag(true) allows linear effects to
preview more quickly when multiple tracks selected, by
pre-mixing selected tracks.
Simple generators like Tone and Noise may be marked as
'linear' so that they only preview a few seconds.
Generators that vary over time (such as Chirp) must use
the full duration that is set. As this currently
requires calculating the full duration, preview for
'non-linear' generators are not limited to the preview
length.
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.
1) Shell VSTs were completely unrecognized...that is no longer the case
2) All VSTs will now ALWAYS be initialized and cleaned up from the main
GUI thread. I found that some Waves VSTs would freeze Audacity when
initialized in the audio thread and closed in the GUI thread.
3) While realtime previewing, it was possible that the wrong slave
could be used to process new blocks of audio.
4) I found that the Waves AUs don't crash on a real Mac (instead of a
virtual machine), so I removed the "black list" I'd put in just for
them. (Something to do with needing full 3D support I think.)
Anyway, #2 and #3 were quite intrusive, so as much RTP testing as possible
would be a good thing.
It corrects several "multiple project" problems with the
meter toolbars and meters.
In addition, there was a "multiple project" issue where
the transport buttons didn't disable properly in the
non-active project.
This bit the textual mode plain old text based buttons
and retains the bitmap buttons for graphical mode.
It also allowed me to remove the manual accelerator table
building (no access keys in GUI mode) which was a good
thing as I really didn't know if the was gonna work for
non-English keyboards anyway.
If you can believe it, this whole big mess is
just to get localized effect labels back into
the menus.
I sure wish I'd had a little bit more time to
finish up all of the effects. It sure would
be a lot cleaner (code wise).
All:
Export/Import now disabled if the Effect (family) doesn't support it
Options disabled if the Effect (family) doesn't support it
Standarized on "Latency compensation" instead of "Buffer delay compensation"
Correct loading/saving of factory default settings
Fixed "Mannage" to be "Manage"
Removed conditional code since we're keeping the transport buttons
Play bases state on actual playback status
Play no longer monkeys with selection
Play will now start from where it left off IF:
The user stops the playback via the Effect Stop button
If the user wants to restart from the beginning of the selection
then the user can click Rewind while stopped.
Rewind will not go past start of selection (sorry Steve ;-))
If Rewind is clicked while not playing, playback will next
start at beginning of selection.
Fast Forward will stop at end of selection
However, if FFwd is clicked while not playing, it will
put playback at the end of selection and the next time
the user clicks the Effect play button, playback will
continue from the end of selection to the end of track.
Deleting a preset now prompts user to confirm
Button faces should now look a little better
Bypass (should we rename that???) button now grays when disabled
Audio Units:
Corrected all user visible "AudioUnit" strings to be "Audio Unit"
Removed unneeded "Buffer Size" in settings dialog
Only uses latency if user said it was okay
Ladspa:
Added settings dialog to allow control of latency usage
Removed unused "user selectable" buffer size
Only use latency if user wants it
Refresh controls when presets are loaded
VST:
Removed unused "Rescan at startup" setting
Propogate parameter loads to slave effects
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.
Needed to redo a bit of code so that effects would work
without the rack in the middle. I wanted to disconnect
it completely as I'm not sure it something that will be
kept around.
During realtime preview, effects will be applied in the
order their dialogs were opened...hmmm...what happens
if they don't have a dialog??? I look into that.
Fixed the focus target for windows when cycling among
active windows as suggested by David B.
Fixed plugin registration if the plugins were located
in the "Plug-ins" folder. I believe this problem may
have played a role in the duplicate menu items.
