bool CAVoice::remove ( CAMusElement elt,
bool  updateSigns = true 

Removes the given music element elt from this voice, if the element is playable or from all the voices in the staff, if non-playable and part of the staff.

If updateSigns is True, startTimes of elements after the removed one are decreased including the shared signs. Otherwise only timeStarts for playable elements are effected.

This function doesn't destroy the object, but only removes its reference in the voice.
Due to speed issues, voices are NOT synchronized for every inserted element. User should manually call CAStaff::synchronizeVoices().
Returns true, if the element was found and removed; otherwise false.
