I am with Spalding on this topic..I have always been comfortable with my G1000 on board sequencer and now the G70 sequencer...

For the same reasons as Spalding...Immediate access to anything I want to sequence or edit...correcting sequence problems..eliminating system exclusive problems..all can be quickly done right on board...anywhere..

Maybe an elaborate start to finish project in the studio..the PC has merit, but for everyday..spur of the moment..give me the on board sequencer..
Now I am use to Roland..maybe other brands may or may not fair as well...
