The AP20 GPIO themselves are transition triggered. At least with a direct connection between switch and AP20, you need to click repeatedly for larger volume changes. If you simply keep it pressed, only one step is changed.

If you have something inbetween with autopulsing etc., however, that could be different.

In older cinema's in our chain we have "so called" FTT Remote control box (maybe you've seen them) and in that cinemas i didn't had this kind of problem. But in this one one of the guys from integrator company made his own control box with micro-relays and some electronic for which i don't have schematics which gives me a headache (if you know what i mean)
