Well, this commit got a bit out of hand, what with 26 files changed. Oh well.
Basically, we're using the buffermanager to dispense temporary buffers for playhandles and audioports to use.
This allows us to change the way playhandles work. Earlier, playhandles of the same track were waiting in line
to push their output to the audioport. This was of course inefficient, so now they just register themselves to the port,
then the port handles mixing the buffers.
Caveat: this is still a work in progress, the vol/pan knobs on instruments are temporarily non-functional - will be fixed in
the next commit, but I have to get some sleep now.
Use dynamic building of jobqueues with dependency counting:
- At the start, each channel that has no dependencies is added automatically to the queue
- Then, after each channel is processed, it increments the dep.counter of all its recipients
- When a channel's dep.counter hits the amount of its dependencies (senders), it gets automatically added to the queue
- The queue is finished when the master channel has been processed
- Muted channels are automatically processed at the start regardless dependencies, because they don't have to care about senders, being muted
Hopefully this will improve Fx Mixer performance.
LMMS now properly builds and runs with Qt5. Various deprecated functions
had to be replaced like QString::toAscii()/fromAscii(). Also occurences
of FALSE/TRUE have been replaced with false/true.
LmmsStyle now derives from QProxyStyle and sets a style instance as base
style (Plastique for Qt4, Fusion for Qt5).
MOC files are not included anymore but added as regular source files.
What's missing is support for embedding VST plugins into a subwindow
inside LMMS on Linux/X11 due to missing QX11EmbedContainer class in Qt5.
Build instructions can be found in INSTALL.Qt5
Minimum version requirement for Qt4 has been raised to 4.6.0 for best
API compatibility between Qt4 and Qt5.
- Remove the redundant hasSampleExactData() function. Instead, signal lack of s.ex.data by returning a NULL in valueBuffer()
- Cache s.ex.buffers and only update them once per period
- Make valueBuffer() in AutomatableModel threadsafe so that it can be used for NPH's sharing the same model
- Add sample-exactness to instrumenttrack's vol & pan knobs
Since addition of automation, controllers etc. the freeze functionality
has been rather broken and thus adds no value anymore. In order to not
confuse users with broken functionality, remove it at all.
Closes#345.
Use the extra information to determine whether we need to process input
at all if plugin is not running anymore.
In FX mixer we now omit starting effects if no data has been mixed to
a certain FX channel. Instead let effects running until they finished.
First of multiple fixes for #267.
We lost short peaks because the display update rate usually is much lower
than the number of audio buffers processed per second which lead to lost
peaks. We mitigate this issue by caching the maximum peak value until the
next display update where it is reset.
There once have been huge efforts to implement FX send support in the
master branch. In order to make it available on a stable base here's
a backport which is non-trivial as there have been major rewrites of
the mixer's worker thread architecture.
There still seem to be bugs which we have to fix before merging into
stable branch.
Thanks to Andrew Kelley for the original work.
We must not process the FX mixer if we notice that currently a pattern
is frozen. Furthermore renamed some state-reading messages of the
pattern class.
Closes#3316495.
Most files and most of the core classes and their methods have been
renamed to match new coding style conventions:
391 files changed, 25400 insertions(+), 25598 deletions(-)
Furthermore splitted some files where model and view classes were
declared or implemented together in the same file.
Should be tested thoroughly as I might have missed renaming some virtual
methods or SIGNAL/SLOT parameters.
