# -*- coding: ISO-8859-1 -*- """ capellaScript -- (c) Paul Villiger >>> Notenzeilen transponieren Mit diesem Skript können einzelne Notenzeilen einer Partitur oder die ganze Partitur transponiert werden. Die aktuelle Tonart und die Notenzeile an der Cursorposition werden in den Dialog übernommen. Auch Transposition nach Instrumentenstimmung ist möglich. Neu lässt sich ein ganzer Ordner transponieren. <<< History 25.09.2004 - Erstausgabe 12.10.2004 - Transposition nach Instrumentenstimmung - registerUndo() eingebaut 06.11.2010 - ganzen Ordner transponieren 19.01.2011 - Fehler bei unterschiedlicher Zeilenanzahl pro System Bemerkung: Das Transponieren erfolgt 2-stufig. Zuerst wird von der aktuellen Tonart nach C runter transponiert und danach wieder zur Zieltonart rauf. Oktavierungen können bei Bedarf in einem zweiten Durchgang ohne Transponieren erfolgen.
