hey bill...i guess it's like someone else mentioned in an earlier post, it depends on how serious you want to get...i still recommend you(and i KNOW this takes time and is a PIA) record each instrument individually and then go and edit each one seperately and then together...this way you get total control over the entire mix, not just pre-set levels eq and panning according to the techs at yamaha.I mean i even go to the trouble of splitting the drum track (whislt still in MIDI form) into the various single intruments and then edit and effect them indivudually, but thats just me....but just editing the "whole arranger mix" in toto doesnt give you the control necessary to get a good mix all the time, albeit its a LOT LOT easier and quicker....as i said depends on how serious you are, and how much time you have...
cheers
