Hello Johannes,
you are using a Global "stopp" button. So just use this
global in every instance (copy and paste!). Or you can create a Stop-button control at the front panel and use it with some local variables (context->create->local).
See example pic: control is in the upper left corner, several locals all over...
Best regards
Gerd
