Don't let me talk you out of anything - the only reason I backed off of a full Maths was I wanted room for a few other things in the limited (126HP) space that I've got, so I opted for a Function plus the WMD/SSF SPO as an attenuator/attenuverter. There's a lot of folks who swear by Maths, and for good reasons. And for what it's worth, I really wanted Clouds as I love the sound of what you can do with it so I bought it. It hasn't arrived yet...
