You can use "amidi", from "alsa-utils": $ amidi -S 'F0 43 10 4C 00 00 7E 00 F7' sends an XG Reset to the default port; `man amidi` for details. To can use "echo", too: $ echo -ne '\xf0\x7f\x01\x06\x02\xf7' > /dev/midi01 BTW, you can try a MIDI realtime message "start" like this: $ echo -ne '\xfa' > /dev/midi The message "f0 7f f7 06 02 f7" is not a valid MMC command, because the device-id 0xf7 is also the EOX status byte. It should be a number between 00 and 0x7f. Regards, Pedro
