What I meant was that with the Aux switch, you can set the different parameters e.g. mix to max and min values. So if you assigned Tip to change mix from 10% to 90%, every time you pressed that footswitch, the mix value would change from 10% to 90%. Now you can assign one footswitch to lots of parameters, so one footswitch could control mix, delay time, modulation depth, etc. My idea was to set a footswitch so that when you pressed it, the parameters are changed to phaser settings. However, these settings apply to all the different modes (Vintage, Reverse, Loop) and thus the setting for depth on vintage will not sound the same as the same setting on tape delay. That was what I was getting at.
