Preload SynthDef into Supercollider


Question. I am trying to make Jupyter interact with SuperCollider using Foxdot. So far it works. But I am wondering if it is possible to interacting directly without starting up Foxdot.

Without starting up Foxdot it gives the following error

*** ERROR: SynthDef startSound not found
FAILURE IN SERVER /s_new SynthDef not found

When starting up Foxdot (after SuperCollider off course) and closing it directly. The interaction with Jupyter and Supercollider works as a charm.

So, is it possble to load the Synthdef settings as a script in SuperCollider?

Many thanks in advance!
