Hello there,
My SuperCollider code (using a bunch of Trill sensors) works fine, when I execute it. Now I am trying to run it on boot, but when I launch it on boot the TrillCentroids UGen cannot be found.
Nov 03 17:17:11 bela stdbuf[242]: ERROR: Class not defined.

Nov 03 17:17:11 bela stdbuf[242]: centroids = TrillCentroids.kr(i2c_bus, i2c_address, thresh, prescaler);
I have extended the waiting time after boot, but that doesn't work.
This is the SuperCollider code that I am running:

And there's a small CPP file to add the Trill library:
/***** SC_libs.cpp *****/
#include <libraries/Trill/Trill.h>
Do I need to add the Trill UGens in some kind of special way, when launching on boot?
Kind regards,
Sjoerd
