Trying to use my M-Audio Axiom 25 in LMMS, but whenever I open the program the default midi settings are set to dummy(no midi support)... when i select another option in set up, a message appears stating that the changes won't take effect until restarting the program.... when i hit ok and open the default preset, click on midi, enable midi... there is no piano icon with a down arrow.... whenever i close the program and restart it the settings go back to dummy(no midi support)....
