Just another question:

i'd like to control the masks of each master seperately. I.e. the menu command "delete mask" seems to delete all masks of all masters. is there a way to delete only the one of the active master?

yes, mm handeling in FL is very ancient. Even if your masters are 100% compatible. MM building in FL changes often the startpoint numbering or loosing one point very close to an other point, so you have to work on and fix the genereted fonts to clean up things what could and should worked from start.

There is the masters panel, where i can switch views of different masters (this is exactly what i want), but this only works in drawing and metrics windows, not in glyph window. the masters panel goes away if i go to glyph window, and it can't be activated (greyed out) in view menu.

I think we have to agree on some FL terms before going forward. What is the Drawing Window? I do all of my drawing in the Glyph Window and I am able to switch between masters quite easily. Perhaps when you say Glyph Window you are really referring to the Font Window. You can easily change the display of the Font Window by adjusting the MM sliders in Font Info.

As to FL MM being ancient. All you have to do is be precise when you create your outlines, pay attention to number and location of points. Tell FL never to add points and Never use the Blend Function to make an MM. Mask-to-Master is a much better way to go.

thanks, this was what i was looking for: the MM slider to set default.

(yes, i was mixing up FL-terms ... I meant the font window, where i found no way to see all the glyphs in the master i wanted.)

now it works. for the moment at least :)
