I personally loved @nathan’s legendary thread on NamedControl: a better way to write SynthDef arguments… to date it’s the top thread of ALL TIME!
I’ve only used NamedControls since the day I read it.
While they certainly add a touch of mystery to the uninitiated… for them a var is far less distracting & wizardly at a glance.
If they ever need a solid primer to understand the genius of using them, @nathan’s article is the definitive source, just send them there.
However, at the same time I couldn’t agree with @jamshark70 more… early users come here for education, not to be mesmerized by the esoteric & enigmatic.
