Hi, when I first got my E-synth ultra off of ebay I noticed that during loading of samples or banks from a scsi hard disk I could hear wierd noises.  This never bothered me until I recently started using EOSlink and I hear a constant tick-tick sound whenever its running.  Does anyone know why this happens and if I can do something about it?  Thanks 
 
Also, I can't get any sound out of submix 2.  I can route voices to submix 2 just like 3 or 1, but I get no sound coming out.   Does this definitely mean that submix 2 is broken?
