For those who prefer SMF above arranger-playing :
In my (limited?) view, using SMF is the same as using karaoke-tracks. When you use karaoke songs they can sound like the original songs, but hey ..... I'm a musician, NOT a discjockey !!

Within a few seconds it's clear to me wether the playing is 'live' or fully sequenced (SMF)..... 'the easy way'. Please have a listen at the 'demo/songs' homepages of various members and many things become clear!

Bill is very right!
