The Yamaha AN1x Synthesizer mailing list

Ok, my AN1x should arrive in the mail next week, so meanwhile i am 
contemplating how i am going to hook it up to my computer.  I have 
never messed with a "real" synth through a computer so i am really 
nervous about doing something wrong, so these may seem like stupid 
questions to many.  I have a soundblaster audigy platinum which has 
midi DIN interface in the front.  Should i hook the AN1x to the 
audigy with the computer shut down and then turn the computer on?  
Should i leave the AN1x turned off until the computer is turned on or 
do i turn it on before i power the computer up?  Can i use the 
AN1xedit program with my audigy or do i need a special soundcard to 
use that program?  

I am sure i will have plenty of questions once i get it all setup and 
start trying to download patches and use the anxedit program, but for 
now these are just the ones i need answered so i can get started.  
Thanks!
