Dj Dab seems to have lots of things with knobs and switches around his studio. However what caught my attention was the Mod gallery detailing some of the EEPROM swapping and programming for the Drumulator, HR-16, and other drum machines. I guess the guy sells his programmed chips for very reasonable and I guess has glitch ones as well. The website does have a backdoor to the directory listing with some cooler stuff that is not on the webpage. Look around for yourself. http://www.djdab.com/dabframes/DIY/
