When fx is activated the ratio x/y is not on zero (means that when you push fx button on vestax spin 2 the fx is already active and you can hear it). Second idea is allow fx change by pressing buttons on the controller instead touching the ipad screen. Excuse me for my english, i’m italian. Thanks
The FX Pad cannot be controlled via a controller. You can change the FX parameters in the “Manual” FX option. The “FX Param” knob on your Spin 2 corresponds to the FX parameter slider above the Wet/Dry slider in the Manual FX section.
