Chapter 5 - Recreating the beep synth

Compile errors

There are a number of common errors you might see.

You haven’t started the server

WARNING: server 'localhost' not running.

If you see this, you are trying to do things in the SuperCollider REPL but haven’t started the server. You can use the menu command Server -> Boot Server to do it.

Or conventionally you can set the variable s to the server and invoke methods on it:

=Server.local;

s.boot;

s.quit;

(it’s only a convention, can use any variable here…)

Wrong file name error

If you get the error ending in:

^^ The preceding error dump is for ERROR: Primitive '_FilePutString' failed.
Failed.
RECEIVER: a File

You didn’t edit the file name in the synth def and it can’t save the compiled output

}).writeDefFile("/Users/gordonguthrie/.synthdefs"))

If you see errors like this in the ~/.sonic-pi/logs/scsynth.log

*** ERROR: SynthDef sonic-pi-mythirdsynth not found
FAILURE IN SERVER /s_new SynthDef not found

Something has either gone wrong with your synth naming, or you are not loading the synthdefs from where you have stashed them.
