Did not expect this big difference as was thinking that swing and the groove of not being in perfect timing would be more important.
But even though this is in perfect timing and just adjusting how the notes would hit the strings of a guitar makes a really big difference and if I did not know or not paying a lot of attention my ears would think that it is a real guitar being strummed... and yes without even starting to mess around without the velocities either...
P.s there is many more tutorials and other stuff with downloadable files as well at this YouTube site.
