MIDI issue on MSI K7N2
 

Like Murphy's law, it's not untill you need something that you realise that you don't have it.

My motherboard doesn't include the MIDI socket so I was wondering what sound card do you guys recommend me that, of course, has MIDI support.

How about using a external sound card, like Sound Blaster Audigy 2 NX

I have never used it before so not sure if its worth it or not.

Well I'm not comfortable using a USB device for my sound card, maybe if it's the last resort. Still, it doesn't have a MIDI port.
