I have added a noise channel component for the FM chip of my SEGA Mega Drive MIDI Interface. The aim is to simply offer a little more variety in terms of what sounds can be achieved with the YM2612, so it's quite basic at the moment. The channel (which is actually a 'half channel' as it is split with FM channel six / the DAC channel) has the following features:

• 3 bit volume control is mapped to velocity
• 6 bit frequency control is mapped to pitch (specifically, notes 0 - 59)

A demo video is below.

Nothing I own has MIDI.  I'm probably going to end up shelling out more money than I'd like to talk about for a MIDI device once this is finished.

@ Beverage: USB to MIDI converters are relatively affordable these days, although stay away from the ultra cheap ones (let's say, sub $30 range).
