I think you are mixing things up. Midi is a digital signal without sound (basically on/off, velocity from 1 to 127 and what sound should be played) while audio that's carried by jacks is a sound signal. If the zoom has a midi in/out, it's to be connected to an expression pedal, not to hook it to a computer sound card, you need the GK2A and something that does the translation job to do so.
Midi/Usb converters are useful for midi keyboards, when you need the joystick port to be free (for games or whatever)
