Alesis HR16:B repair


Would anyone have contact information for someone who would be able to diagnose and repair an issue I’m having with a modded Alesis HR16:B. It’s a pretty typical mod, three slots for eprom chips, a pitch knob and a fine tune knob.

The issue I’m having is specific to 4 pads. Bass, Snare, Closed Hat, and Mid Hat. When these pads are triggered it sends the unit into a really bad glitched out mess. I have no idea if this is a typical issue with aging electronic or if it’s related to the modification made. Either way I’d love to have someone who is more knowledgeable take a look at it.

Thanks, and be well!
