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.
Implements a ring buffer class for LMMS, which is designed to be flexible, efficient and thread-safe.
Due to flexible design, it supports various methods of operation:
- set delays/sizes in absolute frame values, ignoring samplerate
- set delays/sizes in milliseconds with samplerate-awareness
- multiple inputs -> single output
- single input -> multiple outputs
Efficiency is achieved by working in buffers and using memcpy/memset for audio operations, except when additive mixing is needed: then MixHelpers are used
Thread-safety is guaranteed with QMutex
