Hello everyone! Having a forum like this is a blessing indeed.

Being a noob in Csound, I’ve been studying ‘The Csound Book’, where some etudes are given to be played in a csound front-end(Winxound in my case).

I’ve copied and pasted a segment of .csd file and the outcome in the compiler window, for a better understanding.

The warning “WARNING: could not open library ‘C:\Program Files (x86)\Csound6\plugins64\py.dll’ (-1)” really bugs the hell out of me :frowning2:

Would be grateful if someone could save me?

Thanks in advance,
Gyu

In this case your biggest problem is the missing “sing.aif” audio file. That’s why soundin cannot open it and the ftable no. 4 never gets created. Which means loscil (probably in inst. 106) complains about an invalid ftable no. 4.00000.

Regarding py.dll, I can’t say much because I’m on Linux. I’ve had an issue with that opcode here because apparently Csound isn’t compatible with python3 yet, but that was because I’d built it myself.

How did you install Csound?
Do you have python installed?
Does ‘C:\Program Files (x86)\Csound6\plugins64\py.dll’ exist as a file?

Cheers.

What version of Cabbage did you install? And did you select to install the Python opcodes?
