Reply to Mapping MPD32 shift button

Just purchased an Akai MPD32 and have been mapping for two deck control in conjunction with an external mixer. I've mapped all the pads to control deck functions and now want to also set up a shift option to make the pads trigger hot cues but have run into a problem.

I have to press my shift button twice to toggle it on/off, which completely defeats the point of the LED feedback, since when it's on the LED is off half the time and vice versa.

I've followed these instructions to make my shift button.



Any ideas why this is happening?
