Hello All,
i'm using monitor opcode to recording a performance but
if i use -j option in command line monitor is not working
(using it with fout give me a blank audio file).
It is right or i'm wronging somethings?

Thanks,
ciao,
francesco.

Attached is a more simplified version of my csd.
Also it is at bottom.
If i comment out the -j2 option it is working.

Thanks,
ciao,
