Spoke too soon..fault 5 to add to the list:

5: According to the manual hitting the chorus phaser button should 1: 
slow down the phaser modulation speed. Yep it does that! 2: add the 
phaser effect to the Synth section. nope doesnt do that..works fine 
on the strings though.

So I have no phaser on the synth section..
