Do you have a ~/.mmac file? If so, remove it and try again.
.mmac file? I don't, according to Catfish.
Any of the rc file candidates might be an issue: mmarc (in current dir), /usr/etc/local/mmarc or /etc/mmarc.
I found /usr/local/etc/mmarc
I deleted it. So, big change. Look:
piteur@MATERIEL-LX:~/Documents/MIDI FILES$ mma ESSAI_00.mma

So, I've done:
sudo mma -G
And mma ESSAI_00.mma results again in a file ESSAI_00.mid !!! (correct midi file, after checking)
Next suggestion? Maybe resinstall mma after ensuring the current program code is purged.
Given what I've just reported, I suppose there's no point in doing:
sudo apt-get purge mma
Thanks a lot!
