Yamaha AW16G effects use....

[hep17]

I recently bought a Yamaha AW16G multi-track recorder... after mixing down and recording a few songs from my Teac 2340 (without adding any effects or EQ) I began the process of final mix-down in preparation of burning it to the CD... I was able to pan the tracks and ad EQ but when it came to the effects it is stuck on Chorus and I can't seem to get out of it to change the effect to something else... I have read and re-read the manual and am no closer to a solution after 2 days of trying... of course it's the weekend and no support from Yamaha available.. If anyone out there owns one of these units, and could give me some insight I would certainly appreciate it... Thanks... and oh yeah, it seems like an awesome machine and was simple to work until this...
