HI, Amplifi 150 , setting delay time exactly is difficult : I am trying to set the delay time on the digital delay effect via the iphone app and it is really difficult to get an exact match - E.g. 467 ms : as the interface is clunky, I end up 20 -50 ms either side. How can I fine tune the delay time ? And a more general question : is there PC software that I can use instead of the iphone app, the laptop would be a better interface. Thanks
