Hi Yvan,

There will always be a part marker on bar 1, that's normal. Every style has A parts and B parts, if there was no part marker there, nothing would play. You'll just have to decide whether you want the A part playing, or B.

Regarding muting the Drums track, right-click in bar 1, select Bar Settings, choose "Mute" beside the Drums track, and click OK.

Then right-click in bar 9, select Bar Settings, choose Back To Normal beside Drums, and click OK.

Now if you click the Generate and Play button, you won't hear drums until bar 9. This will definitely work as long as the track isn't frozen.

Thanks
