Hope this is posting is to the right area as it's my first.

May I say this is such an excellent tutorial. I have learned so much in such a short time and it's greatly appreciated - thank you !  My query is as follows if anyone can shed light on this:

1.  I have been using the brush  to drop the patterns into the playlist.  How do you line them up properly to begin at the start of the bar.  The slightest movement of the brush makes them start early or late of the bar.

2.  Similarly having read your audio clips tutorial, how does one line up (synchronize?) the start of the audio clip apart from wobling around the paintbrush.   Imported audio clips probably don't begin right on the beat I guess. All help appreciated.   Thanks Beebs.
