I'm currently struggling with the following problem - I have ultra light, regular and ultra bold and want to interpolate them in Fontlab MM space, so I could create an extensive family. As it seems, Fontlab MM space does not allow for the use of intermediate design (Normal) to be place between the two masters - ultra light + ultra black. (or am I mistaken?)
So that leaves me with two choices:
1) to keep two MM files with light - normal and normal - black interpolations and constantly troubling about consistency
or 2) use two weight axis in same MM font and do mind-bending slider-switching so I could achieve tri-master interpolation in four-master space ?!?
The discussed type family is still in design stage and I have developed a habit to work/design in MM space, so what should I do... anyone wiling to share some experience, workaround or .. call it trick... how tri-master interpolation could be made possible in Fontlab?
Thank you in advance!
