Instances without Masters?

Hey all - I draw a font, and I need to add more styles in the family (not interpolation needed) and I thought about Instances but seems I cannot set up instances without setting different Masters. How can I avoid making a new file for each style?

Thank you guys

Just add instance? Just click the plus button in the instance page.

and I access with the “Is Active” checkbox to edit??

I dont understand how to edit each one.

Master = what you draw
Instance = is what Glyphs exports

Read this about setting up instances:

Will read - thanks. Meanwhile I just generated all instances and save each as dif files :frowning:
