timidity++ cannot start using its systemd service

[Adel Ahmed]

The timidity service always fails whether I start it manually or automatically:
localhost ~ # systemctl status timidity
● timidity.service - TiMidity++ Daemon

I can run the exact same command in the terminal:
ExecStart=/usr/bin/timidity -iA $TIMIDITY_OPTS

and timidity starts just fine

I'm running this command temporarily to get things going but I'd like to fix my timidity++ service

thanks
