Pitch bend doesn't work on midi keyboard

Using the pitch bend joystick on a midi keyboard doesn't make the pitch bend on beepbox.

I'd assume this stuff was tested on keyboards that don't have such detune knob/pitch bend controls or that it's just too much of a hassle to go through and detect various kinds of keyboards and etc. to see what they can do and therefore implement their recording gimmicks into the program.
