I just built this lovely bit o' software onto a Nintendo Famicom cartridge... its a kickarse realtime NES drum machine/synthesizer that runs on the actual console (in this case one of my Japanese Famicoms) written by Neil Baldwin, features auto echo, a 180hz refresh rate!, pitch sweeps, mad granular sample FX, 6 virtual tracks and the drum 'instruments' can use any of the NES's internal 5 voices simultaneously - more info at http://www.nes-audio.com/

Here's a few sounds - both one shot and looping to show u how it plays...

It is -great- fun :D ta very much to Neil for making the software \o_

PS - I deliberately didnt use env pitch sweep on any of the sounds because well, because it was funnier not to (the NES can produce REALLY heavy kicks this way btw :)
