[LAU] any mididings users here?

[Robin Paulson]

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,
