Fixing regression in Music keyboard widget block with alignment of blocks

[ksraj123]

When hertz or pitch blocks are added to the music keyboard widget through the widget window then ideally the newly generated blocks should connect and align properly with the existing blocks in the clamp of the widget block but this it shows regression.

There seem to be to more "regressions":
(1) the + pie menu is not closed when the widget is closed;
(2) see the attached (after adding a few notes and reopening the widget, an extra octave (to the left) is added for some reason.

Came across another regression, the location of the pie menu which appears on clicking the add button is wrong (fixed).

Thanks for fixing the problem with the piemenu.
I think I understand why the extra keys are added when you add a hertz block -- the block that is added, 291, is rounded down from C4, so it is one octave lower than any of the keys on the default keyboard. Rounding up fixes the problem.
