Buffer.read() fails


When evaluating

~realOwl = Buffer.read(s, "/Users/_path/to/samples_/owl.wav");

I get the following error in SuperCollider 3.10:

ERROR: Message 'nextBufferNumber' not understood.

^^ The preceding error dump is for ERROR: Message 'nextBufferNumber' not understood.
RECEIVER: an EventStreamPlayer

The file path is correct. Am I doing anything wrong?


Are you working in Proxyspace? It looks ~realOwl is an EventStreamPlayer?


I don’t think so. When I reboot the server and evaluate that only line, I get the same error.


Looking at the error message, I suspect that there is an EventStreamPlayer in the variable ‘s’.
What is posted when you evaluate this:


Does it post e.g. ‘localhost’?

Does the same error occur if you run:

~realOwl = Buffer.read(Server.default, “/Users/path/to/samples/owl.wav”);



Nevermind, I was overwriting my local server variable s with a pattern. Thanks! :sweat_smile:
