more EDP noise

[zurrigo <loop-zurrigo@mem.li>]

sorry for interrupting all your MRI bonk bonk klonk klonk

but apart from that thump noise on my EDP i have had a serious high- 
pitch wheeeeeeeeeeeeeeeeeee on the plex' output for a couple of weeks  
whenever a loop is recorded (most audible with an empty loop, naturally)

pitch is about a b''' - what could that be?

thanks again for your help
