Hi Lukas,

Hi List, I am writing my own ugen.

Nice!

Are there any situations when I should NOT define something as ctrl/ cget and use mfun instead?

Good question... Currently, as you know, they are supported in exactly the same manner by the system, though it's possible that they may diverge in the future, hence the CTRL/CGET vs. MFUN distinction. In general, if you are writing UGen routines, it might be better to stick with CTRL/CGET. If one is implementing non-UGen native objects, then the more standard MFUN is preferred. Hope this helps. Best, Ge!
