Keyboard / Mouse Using pad controller as a second keyboard

Hi there,

I am not sure how to ask this properly but basically I have a laptop pad controller (AKAI LPD8), normally used for controlling midi. I would like to use this device to control my shortcuts in foobar2000. The problem is that the program does not really like my controller. When I check the device manager, I saw that my controller is seen as "audio device". Is there any way to make computer see the device as another input device like a keyboard? If I can manage to make controller act like a keyboard I think I can handle the rest, is this possible?

Thanks for your helps in advance!
