Re: another 'wrong type argument' error

Hi all,

For sure… I guess I just never thought of Lilypond as "bleeding-edge" before!  
:)

I don't want any real development bandwidth spent on this issue: If it's a 
matter of just setting a 'minos' parameter and everything works perfectly, then 
great — if it's more than that, or if lowering the minos breaks something else, 
then the dev-pool shouldn't pursue it further.

I appreciate the offer, and will try to send you something the moment I have 
the chance. (Right now, I'm scrambling to get other scores composed, arranged, 
input, and compiled — rehearsals start on Wednesday!)

Thanks (all!) for your help.
Kieren.
