It's an extra button required (Intro) when you load the Registration. Ketron products don't save Intro/Fill as part of the Registration setting.

The argument is you could decide to start the song differently each time and as such this grants you more flexibility. Ofcourse there are those who don't/won't support this.

Thanks,

AJ
