Now you can connect for midi out over wifi or use an usb to midi cable if you like . Play your synthesizers with no need for a PC to play your sounds with 7Pad. Plug a standard USB to Midi interface ( can be a cable ) into the Andoid device using a normal USB OTG cable adapter. Select cable in usb midi out settings of 7Pad and click midi connexion button, play and have fun !
