hi all, bit of a niche question here, i can't get the mididings 'System' function call to work as i understand it. i'm sure i'm doing something wrong, i wondered if one of you could help? i wrote a python patch, but couldn't get it to work. so, i made it simpler and simpler, to try and understand it. in the end i got down to this, which i named 'mididings_test.py': ========================= from mididings import * run( System('aplay /home/robin/autest.wav') ) ========================= now, please note that this is trivially simple, it's not the command i actually want to run, it is purely a way for me to understand how 'System' works. yes, the autest.wav file exists, and it is in that location. and yes, aplay is installed (part of alsa_base) when i run the script ($ python mididings_test.py), it does nothing so, what am i doing wrong here? once i figure that out, i can write the real patch i require cheers, -- robin http://fu.ac.nz - Auckland's Free University
