MIDI in/out thru USB port on Mega

Hi guys, I'm building a MIDI controller for a guitar processor, the downside is the processor doesn't transmit sysex from the MIDI jacks it only does it from it's USB jack.

I ended up getting a DUE to try and use the Native USB on it but the DUE has a been a big headache so I want to switch back to the Mega since it works like a breeze.

I was wondering if its posible to send/receive MIDI with the built in usb jack on the mega without using an app for serial to MIDI

if not, are there any other alternatives to do this? I want to plug the controller into the USB jack of the processor and send and receive MIDI data.

Any help would be appreciated. Thank you in advance!
