Loop Editing, Midi And Audio Syncing Problems, questions I need help with please!! Options

[willismatt]

Howdy there!!!
Just getting excited with Logic Express and I have 2 quick questions....

1) is is possible to f@#$ with samples... ie..can I fade in/out loops??
I am wanting to fade in a synth pad and my mac won't let me.
What are my options???

2) when I am playing the complete track, I occasionally get messages such as..." an error occured with syncing audio and midi".
It doesnt seem to jam my track up but it is a little concerning.
Any help???

Thanks dudes
