- Uses existing functionality in FxMixer & FxMixerView to manipulate channels
- Instruments sending to the manipulated channels get automatically updated
- In the future I hope to implement a drag/drop functionality instead of the clunky context menu but this is a good first step until then
- Also added in a little QWhatsThis help message for the FX line, also accessible from context menu
That lmms_math thing got mixed in accidentally, but it's also a good change: always include math.h in lmms_math - that way, other parts of the software can just #include lmms_math, and won't have to #include both math.h and lmms_math, also the yet unused sinc function in it seems to need it so this prevents problems down the line
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.
