I have been trying to use the SI-Electric Piano and generally it works great how ever the tremelo Rate and Intensity seem to be coupled together.  Is there some way to set the speed and or rate independently of each other?
 
I have been using the mouse is there a different way to control them?
 
 

I hadn't tried it out until I saw your post, but the Depth and Rate controls are working independently for me.

Thanks....wanted to know if it was just me.....
