Yes. But that was a silly question, I was mixing up helpers and observers=

Totally unworkable, you mean. That is, that's the conclusion I quickly ca=

to after giving it more thought.

If you're cut'n pasting by whole bars, yes, but we're not (neither=20
length-wise nor pitch-wise). And that would be against our current note=20
insertion/deletion paradigm. So cutting should replace notes with rests, =
and=20
pasting should be done over a long enough series of rests.

I guess I'll have to check how this is done is Logic, though.

I'm not sure there is an immediate solution for this. You probably can do=
 it=20
by converting the QPixmap to a QImage and then fiddling with=20
QImage::setColor(), but the pixmap<->image conversion is described as bei=
ng=20
slow in the Qt docs.

Did you like the one for The City of Lost Children ? :-)
