How can one remove the empty percussion staff in Grandscore? The \RemoveEmptyStaves seems not working on percussion staff.
Sample files can be reached at http://orchestra.tw/lilypond_Q including: 00.ly bdrum.ly timp.ly v1.ly v2.ly To run lilypond 00.ly (http://orchestra.tw/lilypond_Q/00.ly), and it results in 00.pdf (http://orchestra.tw/lilypond_Q/00.pdf) Thanks very much for any advise~ neuro neu...@gmail.com
