Hi Jack,
Greetings from Melbourne. Yes indeed, the fx controls are enabled and appear to operate as a master for the FX/delays/mod. When at full clockwise there is only delays -BUT- the delays are not in stereo. The pingpong doesn't move from left to right, it just sits in the middle and no amount of tweeking via my ipad seems to make them move left to right. Can you try an experiment for me? Create a new patch with just an amp and place a pingpong delay in the last slot. Can you hear the delays clearly moving from side to side through the speakers? If you can, I'm doing something wrong. If you can't . . . .
Many thanks
