I was fiddling around with an analog synth that went into a peavey km50 keyboard amp and i made this soundit has loads of pitch editing giving it the house-ey feel to it and i think it was an fmaj5/9 chord with extra 6ths and 4ths.
One of my friends had a door that sounded really nice. They were incredible and sent me a very nice small recording of the door opening and closing to upload here.
