Have you tried the so-called 'stop pad'? In a registration you turn it on (all 4 buttons). Then save it in the relevant registration. As soon as you tap this, the Multipad stops, because it has the shortest possible voice. To run a Multipad again, simply click on the next registration. You can do this if necessary. to repeat. Of course you can also just press the Stop button of the Multipad ... If you search on 'stop pad' you will see more information. I hope this helps you, have fun ...
