Hi. I looking for a extended version of the MIDI In module.
When slecting the PC keyboard as input there are only 2x12 keys that are convertet to MIDI Keys..
I need 2x16 !! Any help ?

why not connecting a external midi keyboard?

Because it is for a app that is controlled by a Arduino running as a HUI devise !!
This have a lot of plusses compare to using MIDI.
