groove blox - started already. Need help with arrays and snap to

[Admin]

Dear All, 

I already got drag and drop sort of working - can drag
a wave file to a rectangle and it retains the name of the file - so now
I can play that file once it is dragged to the track view. 

I am not
sure how to make an array - and I assume an array is what I need to keep
track of multiple blocks (there are 4 categories of blocks - drum, arp,
bass and fxfill) 

Also, how would I implement a 'snap to' interface?
