What i meant is where to find the place which makes flagged stems in forced directions longer than unflagged ones (i.e. here the first note gets a longer stem than the second note: \clef treble \voiceOne c'''8 c'''4 ). I supposed that this happens when the flag is attached to the stem, but eventually i found out that lines 346-349 of stem.cc are responsible for this :) Now i'm almost done. However i still don't know how to attach different versions of flags to the stems. For example i've created new flag u4short, and i want to tell LilyPond to use this new flag for stems shorter than 3 staff spaces (and normal flag for longer stems). How can i do this? I searched for "flags.u4" and "u4" in source files and found results only in font source files... And there is one more thing - is it a bug in font sources? When i change total_depth# = 3.5 staff_space# - blot_diameter# / 2; to total_depth# = 3 staff_space# - blot_diameter# / 2; (in definition of u4 flag, line 163 of feta-flags.mf), i get the output in attachment. I've tried other values, and: 2.95, 3, 3.1 are bugged 2,9, 3.05, 3.15 are not bugged What do you think about it? cheers, Janek
