In fact, you want a blank music score with 8 staves.

OK, you can get what you wish :

1- In the mixer, right-click on Melody channel
Select : No MIDI patch

2 - In the PRINT menu :
Select Template : Custom
Enable only :
- staff lines
- Treble clef
- Staves per pages : 9 (to get 8 lines in final).

Done.

Reach for excellence
