How? I have tried to synch the MP so it sounds when I start the intro of a song without any luck...
To have a multipad start when you press a chord, use SyncStart (the button to the left of the four mp buttons). The button will be flashing, just like the style start/stop button.
You can also save this in a registration, so it will sync start automatically when you load the registration. Just make sure the button is flashing when you memorize the registration. It's the same idea as having a style variation button flashing when you memorize the registration -- ie, it will start with a fill.
Hope this helps,
Fred
