Hey I have not had a chance to get the manual quite yet but I had a 
few questions. 
First:  When in grid recording I am tempted to flip back to real time 
and punch in a couple of notes, when I do this however only one beat 
makes it onto the pattern am I doing something wrong?  Of course any 
help would be nice
Second: I am new to making music of any kind so please bear with me, 
I was curious on how most hip hop songs are composed, I know this is 
a newby, "just listen to a song idiot" question but is there a basic 
modle such as 4 bar intro, 16 bar section, 8 bar chorus, or something 
to that effect so I can try to put together a full song?  
Third: If I make a beat with track 1 the kick track 2 the snare, 
track 3 the high hat and its short and I want to cut and paste this 
basic pattern through the song is there an easy way?  
Lastly:If I have a drum pattern and would like to add guitar sounds 
that are loaded in the mophatt can I get the guitar sounds or any 
sound for that matter streched out?  I:E: can I expand the sounds 
make them longer?
I know that there are probably a hundred idiots who ask these same 
questions, but I am committed to understanding this machine and 
making something that is quality.  My mother is sick of hearing the 
crap I have made so far so can anyone help her and I make something 
better?  Thanks a million.  PS if you want me to just read the manual 
please don't let me know that right now I am trying to get it printed 
as I type right now.  thanks again.
