Find and Replace Rhythms

Added 01 Aug 2005

For use with Sibelius 2.x, Sibelius 3.x and Sibelius 4

This plug-in replaces each occurrence of a rhythm with an alternative. The notes of the replacement rhythm can be mapped to any note of the original rhythm.

To use this plug-in, select a passage and choose the plug-in from the menu. Choose whether you want to use British or American English to describe the notes in your rhythms. Choose the start position for the rhythm (Beginning of bar, Offset from beginning of bar, On each beat according to meter, eg, 4/4 would mean the rhythm could start at any quarter note position, 3/8 would mean at any eighth note position, etc.).

If offset from beginning of bar is chosen, then choose a combination of notes one at a time, (clicking OK after each selection) to indicate how far into the bar the rhythm should start. (Less common note lengths are found in the drop-down menu.) When selecting the note that completes the duration, make sure the This is the last note to be added box is chosen before clicking OK.

The next dialog allows you to define the rhythm that you want to change. Choose the duration of the first element of the rhythm. Also, choose whether itís a note or a rest and click OK. The top of the dialog is updated with your previous choices. If you make a mistake click Undo last note, then click OK. When youíve chosen the last note of the rhythm, select This is the last note and click OK.

The next dialog shows a summary of the rhythm youíve entered. If itís correct, then choose OK, otherwise select Re-enter rhythm and click OK.

The next dialog allows you to enter your replacement rhythm. This is similar to the dialog used to enter the rhythm you want to change, except there are two further options. The Tied to next option allows you to define whether the note youíre entering will be tied to the next note. The pitch option allows you to define which note of the original rhythm is to be used for the note youíre defining in the replacement rhythm. In general, this box is pre-filled with the note number of the original rhythm that has the same rhythmic position as the note youíre currently defining. However, you can use the drop-down list to select any other note number from the original rhythm. If you are defining a rest, then the plug-in ignores this value.

When the duration of the replacement rhythm is exactly the same length as the original rhythm, a summary of the replacement rhythm is given. You can choose to either continue or re-enter the rhythm. If you choose to continue, then you have the choice of selecting the voices that should be searched for the original rhythm. Once this choice has been made, press OK and any occurrence of the chosen rhythm will be re-written.

Articulation is not transferred from the original to the replacement rhythm. Lyrics will remain unaffected.

If you have a selection in 4/4 but the rhythm you want to search for could start on any quaver beat, then change the timesig to 8/8 without re-writing the following bars. Then run the plug-in choosing On each beat according to time signature for its start position, then change the time signature back to 4/4.
