* Compensate beat note length when stretching
We allow stretching beat notes to normal notes but the length starts
from -192 so there is a lag for one whole note before any change is
seen. Compensate by setting the oldNote value to 1 when stretching
if the note is 0 or below in length.

This PR fixes issues on systems where `QCursor::setPos()` has no effect
or is not reliable. These issues included knobs moving to fast on some
operating systems. Affected widgets are `Knob` and `LcdSpinBox`.
With this PR, on all operating systems, the `setPos` calls are removed and
the cursor is not hidden anymore, so the mouse keeps moving normally
when changing values of one of the widgets.
As now the previous pointer position keeps moving (instead of being reset
to the original position using `QCursor::setPos`), the mathematics that
translate pointer pixel distance to `Knob`/`LcdSpinBox` value increase
have to be changed:
* The `Knob` transition function is now linear and uses a new factor.
* `LcdSpinBox` now uses float values and saves the current float remainder
(this is actually a separate issue revealed by this fix), leading to a fluent,
non hanging movement.
This atomically unsets the MidiJack reference in AudioJack right before
MidiJack is destroyed. This avoids AudioJack using a destroyed MidiJack
object.
This patch
* makes `m_stopped` atomic
* initializes `m_stopped` correctly to `true`
* moves the initialization of `m_stopped` to the point where jack ports
are already connected
* Multiple effects: Calculation of `outSum` should be after D/W mixing
* CrossoverEQ.cpp: `outSum` must be divided by frames in the end
* CrossoverEQ.cpp: don't overwrite `outSum` in for loop, but increment it
When selecting a Piano Key to mark semitones in the Piano Roll we
select key from the y position of the pop-up menu and not the mouse.
Incidentally these two are most often the same as the menu builds
from the mouse y positon and down. If there is room for it. If there
is no room downward it will create the menu so the lower part of the
frame aligns with the mouse y position.
Fixed by creating a variable to hold the pressed key before creating
the menu.
Knob::friendlyUpdate() can be called after the model is deleted
due to signal-slot connections.
Adding a check for the model fixes a crash due to null pointer dereference.
