I am new to midi and would appreciate any help. I have been using Chordana app with the PXS3000 and it works perfectly. I decided to buy the Korg Module Pro app for the iPad and try it. I find that when I play the Casio keyboard I see the correct keys moving on the Korg app on the iPad , and I can hear some of the sound of the instrument chosen from the app , but I still hear the Casio sound as well . I’m not sure if I am doing something wrong or if I need to change a setting on the keyboard so I only hear the sounds from the Korg module pro coming through. I am using a usb2.0 cable type B to midi cable otr cable to the keyboard . Any advice appreciated .
