@whale-av Thank you it works!
This is my first SysEx I sent throw code.

It ain’t luck, its a choice, Red pill (;

Hello everyone!
new here...
I'm tring to send system exclusive message to my Roland (edirol) SD-80
I'm using ubuntu studio -> qjackctl set puredata midi out to the sd-80 input
pgmout works!

in the manual the message is in HEX: "F0 43 10 4C 00 00 7E 00 F7" (without(""))
this message supposed to set the sound generator mode to XGlite and the module should show that the mode is set...
I wrote this HEX code in a message box (ctrl + 2) then connected the message box to midiout object
entered play mode (ctrl + E) clicked the message box but nothing happened...

Thanks!
