Black key mapping is buggy

[felixxblitz]

I mapped out the entire piano, white keys work fine, but the black ones just don't work. I mapped it with a virtual piano. Pressing a midi key mapped to W will have the app register it just fine (as the midi key being mapped to W), but everything else just won't acknowledge it as such, acting as if the mapping was w. Basically it ignores the shift part of it.
