Hey, does that happen only with `superfm`? It's declared in the the same file as the rest of the synths. It should work fine. Is the server running?

Try to manually add the synth by evaluating the block in `SuperDirt/library/default-synths-extra.scd`. If it works, then SuperDirt was not loaded properly.

It might also just be an old version of SuperDirt that got installed.

Hi Loopier!  
I'm trying to use superfm but it doesn't work. This appears in SuperCollider: \*\*\* ERROR: SynthDef superfm not found  
FAILURE IN SERVER /s\_new SynthDef not found.  
I don't know how to install this feature.  
Regards.  
Martin
