Please I really need help here. I just finished using my M-audio axiom 61 some hours ago. Wanted to work with it again now just to discover that key F and key B isn't working on all octaves, just the two keys alone and it's really giving me concern. Pls family, how can I get this issue resolved. I guess it's not an hardware fault cos it never fell off the stand and I got it new. Pls any help will be so much appreciated.
