could be. ive cwrtainly used it in the past when i notate for real
instruments. but as i mentioned last week, i can only look at the cm/cmn
interface once my semester's obligations are over, i cant do anything until
then.  there is a (staff ) macro in cm that lets you specify the clef(s)
for channel-based layout.
